54A82 - ESAB 54A82 Oxygen Throttle Valve Assembly for W-17/W-500 Torches

Fix Your Leaky W-17 Torch

There is nothing more frustrating than trying to set a perfect neutral flame when your oxygen valve is fighting you. If your Oxweld W-17 or W-500 torch handle is leaking oxygen around the knob, or if the adjustment feels gritty and jumps from low to high without that smooth middle ground, it’s time to swap out the valve. The ESAB 54A82 Oxygen Throttle Valve Assembly is the exact part you need to get that torch running like new again.

This isn't a generic knock-off that might strip your threads; it's the real-deal OEM part designed for your specific handle. We know that the W-17 is a workhorse—some of these torches have been in the field for decades. The best way to keep them going for another decade is to replace the wear parts with genuine components. This assembly comes ready to drop in, replacing the old, worn-out stem and packing that are causing your headaches.

Why replace the whole assembly?
Often, just trying to tighten the packing nut isn't enough, especially if the valve seat itself is scored. By replacing the 54A82 assembly, you eliminate the guesswork. You get a fresh seal and a fresh thread engagement, meaning your flame adjustments will be buttery smooth again. This allows for the precise control you need when you're puddle welding aluminum or doing fine heating work.

Installation is straightforward: ensure your system is depressurized, unscrew the old valve assembly, check the torch body threads for debris, and thread in the new one. In five minutes, you'll go from a leaking safety hazard to a tight, responsive tool ready for the day's work.
