The SÜA propane and oxygen adaptors are small brass fittings for connecting regulators to small disposable cylinders. They are worth considering if you run a portable setup on 1 lb propane bottles and small oxygen bottles, and they are the wrong choice for large refillable tanks. This SÜA propane and oxygen adaptors review is based on the Amazon listing and CGA fitting standards, not hands-on testing.
SÜA propane and oxygen adaptors at a glance
| Item | What the listing says |
|---|---|
| Material | Brass |
| Propane side | CGA-600 (disposable cylinder thread) |
| Oxygen side | CGA-601 (disposable oxygen cylinder) |
| Regulator-side connections | Listed as CGA-200 and CGA-540; verify on the page |
| Size and weight (listed) | About 2.5 x 2 x 1 in, 9.1 oz |
The listing’s thread information should be checked closely, because adapters only work when both ends match your hardware.

What these adaptors do and who they suit
An adapter changes one connection standard to another. The CGA-600 thread is used on disposable propane cylinders, while CGA-200 is the connection on small acetylene-style regulators. A fitting that links those two lets a compact regulator run from a disposable bottle.
This suits hobbyists building a portable, lightweight brazing or heating rig, and people who already own a compatible regulator. It does not suit anyone who wants a certified, fully matched oxy-fuel kit. For that, see the Hobart 770502 oxy-acetylene kit.
How to check the adaptors fit your setup
- Identify your cylinders. Read the valve thread type printed on or specified for your cylinder. A 1 lb propane bottle is not the same as a refillable tank.
- Identify your regulator inlet. Look for CGA-200 or CGA-540 marked on the regulator, or in its manual, and compare it with the adapter’s listed outlet.
- Confirm the fuel. Fuel-gas regulators and oxygen regulators are not interchangeable, and propane tips differ from acetylene tips.
- Check pressure ratings. Disposable cylinders work at their own pressures. Use only equipment rated for the gas and pressure.
- Look for instructions. If none are provided, get guidance from the regulator maker before connecting anything.
Pros and limitations
Pros
- Brass is the standard material for gas fittings and resists corrosion.
- Small and light, so it suits a portable kit.
- Allows small regulators to use cheap disposable cylinders.
Limitations
- Works only with the specific cylinder and regulator types listed.
- Small disposable cylinders run out quickly and offer limited flow.
- An adapter adds a leak point that needs testing each time.
- It is not a substitute for flashback arrestors, check valves or matched tips.
Safe use tips
- Work outdoors or in a well-ventilated space, away from sparks and open flame.
- Keep oxygen fittings free of oil and grease, because oxygen can ignite them.
- Do not force a thread that does not fit, and never use adapters stacked together to cross-connect unrelated gases.
- Leak test each connection with soapy water before every session.
- Fit approved check valves or flashback arrestors on both gas lines.
- Store cylinders upright and away from heat, and replace any fitting with damaged threads.

Frequently Asked Questions
What do CGA-600 and CGA-601 mean?
CGA numbers are Compressed Gas Association connection standards. CGA-600 is the thread commonly used on disposable fuel cylinders such as 1 lb propane bottles, and the listing pairs CGA-601 with disposable oxygen cylinders. Confirm the numbers on the live listing and on your cylinders, not just their names.
Can these adapters connect a regulator to a large propane tank?
No. According to the listing they are meant for small disposable cylinders, such as 1 lb or 14.1 oz propane bottles. Larger refillable propane tanks use different valves, so you need a regulator and hose designed for that tank.
Do these adapters turn a propane torch into an oxy-propane welder?
No. They only change a thread. Oxy-propane cutting and heating needs matching oxy-propane tips, correctly rated regulators, hoses and flashback protection. Adapters alone do not make a setup safe or suitable for welding.
How should I leak test an adapter?
Connect the adapter, open the cylinder valve slowly and brush soapy water over each joint. Bubbles mean a leak, so close the valve, release pressure and fix the connection. Do not use oil or grease on oxygen fittings, and never use a flame to look for a leak.
Conclusion
The SÜA adaptors are a niche but useful fitting for small disposable-cylinder setups. Verify every thread on both sides, leak test each time, and use proper regulators and safety devices.
