2115137 - ESAB Replacement O-Ring Seal 4.237 ID x 0.103

Keep Your ESAB Machine Running Smoothly

Don't let a worn-out seal stop your production. The ESAB 2115137 O-Ring is the exact replacement part you need to fix leaks and ensure your welding machine is sealed up tight. Measuring 4.237 inches on the inside with a thickness of 0.103 inches, this O-ring is designed to fit perfectly into your ESAB equipment without the hassle of guessing sizes at the hardware store. When you're in the middle of a job, you need parts that fit right the first time, and sticking with genuine ESAB components is the best way to guarantee that.

O-rings might look simple, but they do a heavy-duty job. They keep dust out of sensitive electronics, keep coolant where it belongs, and ensure that gas pressures remain stable. Over time, rubber seals can dry out, crack, or flatten, leading to pesky leaks that can cause bigger problems down the road. Swapping out your old O-rings during routine maintenance is a cheap and easy way to prevent unexpected downtime. This part is built tough to handle the heat and grit of the shop, so you can install it and forget about it.

Whether you are rebuilding a unit or just fixing a specific issue, having the right seal on hand is key. This O-ring is made from durable material that resists taking a "set," meaning it keeps its springiness longer to maintain a tight seal. It's a small part, but it plays a big role in keeping your welder operating at peak performance.

Installation Tip: Make sure the groove where the O-ring sits is clean and free of old grease or grit. A little bit of O-ring lube goes a long way in helping it slide into place without pinching. Get your machine back to factory specs with this genuine ESAB replacement.
