The Uniweld Type17-0 weld/braze tip is a small, size 0 torch tip for light welding, brazing, soldering and heating. It is worth considering if you already own a compatible Uniweld-style handle and work on thin steel or small copper joints. Skip it if you need to weld heavy plate or are not sure what your torch handle accepts. This review is based on the Amazon listing and manufacturer and retailer specifications, not hands-on testing.

What the Type17-0 Is and Who It Suits
A size 0 tip delivers a small flame. That makes it a fit for thin sheet metal, small brass or copper fittings, light heating and soldering-style jobs. It is not a cutting tip, and it is not meant for thick structural steel.
Key design points from the product description:
- Copper elbow: copper moves heat well and is common on small brazing tips.
- Brass mixer and nut: brass threads tend to hold up better than soft aluminum under repeated tightening.
- Two O-rings: they let you seal the tip nut by firm hand tightening instead of a wrench. Do not over-tighten with tools unless the maker says so.
- Light weight: a small tip reduces fatigue when you hold a torch overhead or in tight spaces.
It suits hobbyists doing light repairs, HVAC and plumbing hobby brazing on small copper, and anyone who wants a spare small tip for a Uniweld-style handle.
How to Check the Type17-0 Fits Your Setup
- Identify your handle. Look for the maker and model on the torch body. Tips are usually not universal between brands, so a Victor, Harris or generic handle may not accept this tip.
- Match the fuel. The tip is sold for several fuel gases, but your regulator, hoses and handle must also be rated for the fuel you use. Oxygen-acetylene and oxygen-propane setups use different tips and pressures.
- Check the size for the job. Size 0 is small. For thicker work, look at the maker’s tip chart for the next size up.
- Inspect the seat and O-rings. Dirt, nicks or a flat O-ring will leak. Replace damaged seals.
- Confirm the pressures. Use the maker’s chart. Acetylene working pressure must never exceed 15 psi (1 bar).

Pros and Limitations
Pros
- Small, light tip for fine work.
- Copper elbow and brass hardware are sensible materials for a torch tip.
- Hand-tightened nut with O-ring sealing is quick to change.
- Listed for multiple fuel gases by retailers.
Limitations
- Only suited to thin steel and small copper work; not for cutting.
- Handle fit is specific. Buying without checking is the main risk.
- Multi-gas listings do not mean every gas is right for every job. Heat output differs between acetylene and propane.
- Warranty terms are not clearly stated in the listing, so ask the seller or manufacturer before relying on one.
Safety and Use Tips
- Leak test every connection with soapy water, never with a flame.
- Keep oil and grease away from oxygen fittings.
- Use flashback arrestors and check valves on both gas lines.
- Wear shade-appropriate eye protection. Brazing and gas welding commonly use a lower shade than arc welding, so check the filter’s chart.
- Ventilate. Brazing fluxes and cadmium or zinc coatings release harmful fumes. Clean coated metal and use proper respiratory protection.
- Clean the orifice with the correct tip cleaner. Do not use drill bits or wire that could enlarge the hole.

Frequently Asked Questions
What can the Uniweld Type17-0 tip weld and braze?
Uniweld lists the Type17 size 0 for welding steel up to about 5/64 inch and brazing copper up to about 1/2 inch. It is a small tip, so it suits thin sheet, light repairs and small plumbing joints, not thick plate or large heating jobs.
Does the Type17-0 tip fit my torch handle?
Retailer listings say it fits Uniweld 71 and WH550 style handles, but the Amazon listing may differ. Check your handle model and the tip seat before ordering, and test every connection with soapy water once it is installed.
Can I use the Type17-0 with propane or MAP-Pro?
Retailer descriptions say it is a multi-gas tip that works with acetylene, propane, propylene (MAP-Pro style) and natural gas. For fuels other than acetylene, Uniweld notes a larger tip size and different pressures may be needed, so follow the chart for your fuel.
Is the Type17-0 good for beginners?
Its small size and hand-tightened nut are friendly, but oxy-fuel welding and brazing still need training. Learn flame setting, leak checks and shutdown order from your torch maker, a class or an experienced welder before working on real parts.
Verdict
The Type17-0 is a sensible small tip if it matches your handle and your fuel. Confirm the fit first, use it within its thin-metal range and follow standard oxy-fuel safety practice.
