187W01 - ESAB 187W01 Replacement O-Ring .301 ID x .070 (5-Pack)

Stop Leaks Before They Ruin Your Weld

There is nothing more frustrating than chasing a gas leak in your welding setup. You can hear the hiss, or worse, you see the porosity in your weld puddle despite having your flowmeter set correctly. Often, the culprit is a tiny, worn-out O-ring that costs pennies but saves you dollars in wasted gas and rework. The ESAB 187W01 O-Ring kit is the simple fix you need to keep your equipment running tight and your welds clean.

These O-rings are sized perfectly (.301" ID x .070") to replace the worn seals in your ESAB gear. Whether it's on the back end of your MIG gun, inside a TIG torch back cap, or part of a gas connection, a fresh O-ring restores the seal instantly. Over time, rubber seals dry out, crack, or get compressed flat, losing their ability to hold pressure. Swapping them out is one of the easiest maintenance tasks you can do to improve your weld quality.

We know how easily these small parts get lost in a busy shop, which is why this SKU comes as a convenient pack of five. Throw a bag in your toolbox or consumables drawer, and the next time you spot a leak or perform maintenance, you'll be ready. Don't let a fifty-cent part hold up a thousand-dollar job. Trust genuine ESAB parts to fit right the first time and hold up to the rigors of the welding environment.
