A short acetylene hose can make a compact torch setup easier to manage, but only when the hose length and fittings match your equipment. The Uniweld H11 Acetylene Single Hose is a 6-foot, 3/16-inch I.D. Grade R fuel-gas hose with an “A” connection, built for acetylene service. Its short reach, red color coding, left-hand fuel-gas fitting, and 200 PSI maximum working-pressure rating make it a focused choice rather than a universal hose. This review helps you decide if the H11 fits your regulator, torch setup, workspace, and safety needs.
Quick Verdict
Rating: Recommended with caveats
Best For: Compact acetylene torch setups that use a 3/8″-24 “A” fuel-gas connection and do not need more than 6 feet of hose.
Bottom Line: The H11 gives you a purpose-built Grade R acetylene hose with clear red identification, an “A” connection, and a compact 6-foot length. Its main tradeoff is that the short reach and specific fitting size will not suit every torch or regulator setup.

Key Takeaways
- The H11 is a 6-foot, 3/16-inch I.D. single hose intended for acetylene service.
- Its “A” fitting is 3/8″-24 and uses the left-hand thread convention for fuel-gas connections.
- The red hose color helps you distinguish the acetylene side from green oxygen hose in an oxyfuel setup.
- Uniweld uses 8-sided crimp ferrules on its oxyfuel hoses, adding reinforcement at the hose ends.
- The 6-foot length is convenient for compact benches and portable work, but it can restrict movement on larger jobs.
- Grade R is an acetylene-focused hose choice, so you should not assume it is suitable for propane or other alternative fuel gases.
What Is the Uniweld H11 Acetylene Hose?
The Uniweld H11 is a short single fuel-gas hose for acetylene equipment. Unlike a twin oxyacetylene hose, it supplies only the fuel-gas side, so you would use it where your setup specifically calls for a separate acetylene hose rather than a joined oxygen-and-fuel pair.
Its 6-foot length keeps excess hose off a small workbench or service cart. The 3/16-inch inside diameter and “A” connection also make compatibility more specific than simply buying any red welding hose. Before ordering, you should confirm both the hose length you need and the thread size on the equipment you plan to connect.
Who Should Buy It?
Best For
- You need a short replacement acetylene hose for a compact oxyfuel setup.
- Your regulator, torch, check valve, or flashback arrestor uses the matching 3/8″-24 “A” fuel-gas connection.
- You prefer a separate single acetylene hose instead of replacing an entire twin-hose assembly.
Skip If
- You need more than 6 feet of reach around a vehicle, fabrication table, or shop floor.
- Your equipment uses a 9/16″-18 “B” connection instead of the smaller “A” fitting.
- You plan to run propane or another alternative fuel gas that calls for a different hose grade.
Before You Buy: Confirm the fitting size before ordering. H11 uses an “A” connection, while H11B uses a larger “B” connection. A hose that looks right but has the wrong fitting should not be forced, adapted casually, or used with damaged threads.
Design, Build, and Hose Construction
The H11 uses Uniweld’s flexible oxyfuel-hose construction with red color coding for the fuel-gas side. That color distinction matters in a two-gas torch system because it gives you an immediate visual cue between the acetylene line and the oxygen line.
Uniweld also specifies 8-sided crimp ferrules on its oxyfuel hoses. Those ferrules reinforce the termination points where repeated bending and handling can put extra stress on a hose. You should still inspect the hose near both fittings before every use because a strong crimp does not make a worn, cut, cracked, or leaking hose safe.
Fit, Compatibility, and Left-Hand Thread Safety
The H11 uses Uniweld’s “A” connection, identified as 3/8″-24. The fuel-gas side uses a left-hand thread, a standard safety convention that helps distinguish fuel-gas connections from oxygen connections. This design reduces the chance of accidentally connecting the red fuel hose to the wrong side of compatible equipment.
The key buying issue is not just “acetylene hose” compatibility. You also need the correct connection size. If your torch or regulator side uses a “B” fitting, the H11B is the corresponding 6-foot Uniweld model with that larger connection. Check the equipment manual and fitting markings rather than guessing from hose color or appearance.
Pro Tip: Before replacing a hose, compare the old fitting to the equipment specification and confirm whether your system uses “A” or “B” connections. That simple check can prevent an unusable purchase and avoids the temptation to force mismatched threads.
Understanding the 200 PSI Hose Rating
Uniweld rates the H11 at a maximum working pressure of 200 PSI. That figure describes the hose’s pressure capability. It does not mean you should set an acetylene regulator anywhere near 200 PSI.
Uniweld’s operating guidance states that acetylene delivery pressure should not exceed 15 PSIG under flow conditions. Actual torch operating pressure depends on the tip, process, equipment, and manufacturer instructions. Use the pressure specified for your torch and tip, and never exceed either the equipment recommendation or the hose working-pressure limit.
This distinction is one of the most important points in the review. Treat the 200 PSI number as a hose specification, not as a target setting for acetylene use.
How It Performs in Real Use
Compact Bench and Brazing Work
At 6 feet, the H11 keeps a small torch station tidy and limits the amount of loose hose around a bench. That can be useful for brazing, heating, repair, or light fabrication work where the regulator and work area remain close together.
Automotive and Equipment Repair
The short hose can work well when the cylinder cart stays close to the repair area. The limitation appears when you need to move around a full vehicle, reach across a larger bay, or work on several sides of a project without moving the cart.
Fabrication and Cutting
The 3/16-inch I.D. and acetylene-specific design make the H11 suitable for compatible oxyfuel work, but hose choice is only one part of a safe cutting setup. Your torch, tip, regulator, oxygen line, check valves or flashback arrestors, and operating pressures must all match the job and manufacturer guidance.
Portable Service Setups
A 6-foot single hose is easier to store than a long shop hose when space is limited. For service carts and compact kits, that can be an advantage. For jobs where the cylinders must stay farther from the work, a longer compatible hose is the better choice.
Ideal Applications for the Uniweld H11 Hose
| Application | Where It Fits Best | Main Limitation |
|---|---|---|
| Metal fabrication | Small work areas with the gas setup close to the table | Limited reach on large assemblies |
| Automotive repair | Localized heating or cutting with the cart nearby | May require moving the cart around the vehicle |
| Brazing and heating | Bench or service work using compatible acetylene equipment | Not intended as a universal fuel-gas hose |
| Portable setups | Compact storage where a long hose would add clutter | Six feet can be too short for open shop work |
Setup and Usage Tips
- Inspect before use: Look for cuts, nicks, abrasions, pinholes, cracks, damaged fittings, or worn areas near the hose ends.
- Match the connections: Connect the red fuel-gas hose only to the correct fuel-gas side of compatible equipment.
- Tighten correctly: Follow Uniweld’s equipment instructions for wrench-tight hose connections and do not force mismatched threads.
- Check for leaks: Use a proper leak-testing solution on connections as directed by the equipment manufacturer. Do not use an open flame to look for leaks.
- Purge as instructed: Uniweld directs users to purge oxygen and fuel-gas passages separately before lighting and to vent gases safely.
- Use the correct operating pressure: Set regulators according to the torch and tip instructions, not according to the hose’s 200 PSI maximum rating.
Compatibility and Safety
The H11 is listed as a Grade R acetylene single hose. You should not treat it as a universal hose for propane, propylene, natural gas, or other fuels. If your setup uses an alternative fuel gas, choose a hose grade and model specifically approved for that service.
Uniweld also advises checking used hoses for damage, especially where they bend near the fittings, and replacing doubtful hose rather than continuing to use it. In an oxyfuel system, check valves protect against reverse gas flow, while flashback arrestors provide additional protection against flame flashback. Follow the requirements of your torch, regulator, local safety rules, and the manufacturer’s instructions for your complete system.
No verified operating-temperature range was found for the H11 in the sources reviewed, so you should not assume that it is designed for unspecified extreme heat or cold. Keep the hose away from hot metal, sharp edges, oil contamination, vehicle traffic, and other conditions that can damage it.
Cleaning, Maintenance, and Storage
Routine hose care is mostly about inspection and protection rather than aggressive cleaning. Keep the exterior free of damaging contamination, avoid tight kinks, and do not drag the hose across sharp edges. If a hose shows cracking, cuts, pinholes, damaged fittings, or suspected leaks, remove it from service and follow the manufacturer’s replacement guidance.
For storage, relieve and shut down the oxyfuel system according to the equipment instructions, then keep the hose in a dry area away from heat, direct flame, sharp objects, and heavy items that could crush it. Coil it loosely rather than folding it into tight bends that stress the hose near the ferrules.
Pros and Cons
Pros
- Purpose-built Grade R single hose for acetylene service.
- Compact 6-foot length works well in small, close-range setups.
- 3/16-inch I.D. and “A” connection are clearly specified for compatibility checking.
- Red color coding and left-hand fuel-gas threading support correct line identification.
- Uniweld’s 8-sided crimp ferrules reinforce the hose ends.
Cons
- Six feet may be too short for larger vehicles, fabrication tables, or shop bays.
- The “A” connection will not fit equipment that requires a “B” connection.
- Grade R acetylene service is not the right choice when your fuel gas requires a different hose grade.
Is It Worth the Price?
Because Amazon pricing can change, the H11 is better judged by fit and use than by a fixed dollar amount. It offers strong value when you specifically need a short Uniweld acetylene hose with a 3/8″-24 “A” connection and you do not want the extra bulk of a longer hose.
It is less attractive if you need more mobility or a different fitting. Paying for the correct hose the first time matters more than choosing the shortest or cheapest option, especially when fuel-gas compatibility and connection type are involved.
How It Compares to Alternatives
If the 6-foot length is right but your equipment uses a larger connection, Uniweld’s H11B is the 6-foot “B” connection version. If you need more reach while keeping an “A” connection, the H12 extends the same basic acetylene single-hose format to 12 feet, while the H13 provides 25 feet.
The H11 makes the most sense when compact size is the priority. For alternative fuel gases, compare a hose specifically listed for that fuel and service rather than assuming a Grade R acetylene hose is interchangeable.
Frequently Asked Questions
What size is the Uniweld H11 hose?
The H11 is 6 feet long with a 3/16-inch inside diameter. It uses Uniweld’s “A” connection, identified as a 3/8″-24 fitting.
Is the H11 compatible with propane or other fuel gases?
The H11 is listed as a Grade R acetylene single hose. Do not assume it is suitable for propane or another fuel gas. Use a hose that is specifically approved for the fuel in your system.
Does the 200 PSI rating mean I can run acetylene at 200 PSI?
No. The 200 PSI figure is the hose’s maximum working-pressure rating. Uniweld states that acetylene delivery pressure should not exceed 15 PSIG under flow conditions, and your actual regulator setting must follow the torch and tip instructions.
Is 6 feet long enough for shop work?
It can be enough for a compact bench, service cart, or close-range repair setup. For larger vehicles or fabrication areas, a 12-foot or 25-foot compatible hose may reduce how often you need to move the gas setup.
How should I inspect the hose before use?
Check for cuts, nicks, abrasions, pinholes, cracks, damaged fittings, and worn areas near the connections. Uniweld advises leak-testing connections with a proper leak-testing solution and replacing doubtful hose.
Does the H11 connect directly to an acetylene cylinder?
In a normal oxyfuel setup, the hose connects to the regulated fuel-gas side of the system, not directly to the cylinder valve. Follow the regulator, torch, check-valve, and flashback-arrestor instructions for the exact connection order in your equipment.
How should I store the Uniweld H11?
After shutting down the system according to the equipment instructions, store the hose loosely coiled in a dry location. Keep it away from flame, hot metal, sharp objects, crushing loads, and other conditions that could damage the hose or fittings.
Should I use check valves or flashback arrestors with this hose?
Follow the requirements for your complete torch and regulator system. Uniweld explains that check valves protect against reverse gas flow, while flashback arrestors add protection against flame flashback. Install and test them only as directed for your equipment.
The Bottom Line
The Uniweld H11 is a sensible choice when you need a compact 6-foot Grade R acetylene hose with a 3/16-inch I.D. and 3/8″-24 “A” connection. Its clear fuel-gas identification and defined specifications make it easy to evaluate, but buyers who need a longer reach, a “B” connection, or a hose for another fuel gas should choose a different model.
