18559 - ESAB Cutting Oxygen Valve Stem Replacement

Fix Your Leaky Cutting Torch

There is nothing more frustrating than a cutting torch that won't shut off completely or hisses when you aren't pressing the lever. If your cutting oxygen lever feels sticky, gritty, or if you hear gas escaping even when the lever is up, it is likely time to replace the valve stem. The ESAB 18559 Cutting Oxygen Valve Stem is the direct replacement part you need to get your torch acting like new again.

This isn't just a generic piece of brass; it's the genuine article for your ESAB or Purox style torch. When the rubber seal on your old stem gets chewed up or hardens from age, you lose that crisp "on/off" action. This replacement drops right in to fix those issues. Installing a new stem stops the waste of expensive oxygen and prevents that annoying popping sound that happens when a leaky valve lets oxygen bleed into the preheat flame.

Installation is generally straightforward for anyone familiar with torch repair. Once installed, you will notice the difference immediately: the lever will have a smooth resistance, and the cutting stream will engage and disengage instantly. Don't struggle with a torch that fights you; swapping out the valve stem is one of the cheapest and most effective repairs you can do to improve your cutting quality.

Why Replace It?

• Stop Leaks: Save money on oxygen and work safer.
• Better Cuts: Crisp start and stop action prevents gouging at the end of a cut.
• Smooth Action: Eliminates the sticky or jerky feel in the cutting lever.
