18K02 - ESAB 18K02 Oxygen Connection for W-201 Torch

Keep Your W-201 Torch Running Safely

If you are running a classic Purox W-201 welding torch, you know it's a workhorse that doesn't quit easily. However, even the toughest torches need maintenance, especially when it comes to the gas connections. The ESAB 18K02 Oxygen Connection is the genuine replacement part you need if your oxygen inlet threads are worn, stripped, or if you are detecting leaks at the connection point. Don't risk your safety or your weld quality with a loose or faulty connection; swapping out the old fitting for a brand new 18K02 restores the tight seal your torch had when it was new.

This part is made from solid brass, just like the original, ensuring it stands up to the daily grind of the shop. It is designed specifically for the oxygen side of the W-201 handle. Remember, in oxy-fuel welding, oxygen fittings almost always use right-hand threads (unlike the notched left-hand threads for fuel), and this part follows that standard to prevent dangerous cross-connections. A secure oxygen connection is critical not just for safety, but for flame stability. If air is leaking in or oxygen is leaking out, you'll struggle to maintain that neutral flame, leading to oxidation in your puddle or popping at the tip.

Replacing the connection is straightforward for anyone familiar with torch repair. It allows you to extend the life of your trusty W-201 rather than buying a whole new handle. Whether you are working in HVAC, automotive repair, or general metal fabrication, keeping your oxy-fuel kit in top shape is part of the job. The W-201 is a legendary torch for a reason, and using genuine ESAB/Purox parts like the 18K02 ensures it stays that way.

Before installing, always double-check that your hands and tools are free of oil and grease, as oxygen under pressure reacts violently with hydrocarbons. Once installed, perform a quick leak test with a soapy water solution to verify the seal. With the ESAB 18K02, you can get back to brazing, welding, and heating with confidence, knowing your equipment is sealed, safe, and ready to work.
