488157 - ESAB Replacement Neoprene O-Ring .801 ID x .070

Keep Your Welder Leak-Free and Efficient

Don't let a worn-out seal disrupt your welding workflow. The ESAB 488157 O-Ring is the exact replacement part you need to fix leaks and maintain the pressure integrity of your welding setup. Whether you are dealing with a gas leak in a torch connection or a fluid leak in a cooling system, a compromised O-ring is often the culprit. This genuine ESAB part is designed to fit perfectly, eliminating the guesswork of sizing generic seals at the hardware store.

Built from tough Neoprene, this O-ring stands up to the harsh conditions of the welding shop. Neoprene is the material of choice for many welding applications because it resists the oil and grime that inevitably end up on equipment. Unlike cheaper rubber seals that might dry out and crack quickly, this Neoprene ring stays flexible and keeps its shape, ensuring a tight seal that lasts. This means less downtime fixing your machine and more time laying beads.

The dimensions of this ring—.801" ID by .070" thickness—are specific to certain ESAB assemblies. Trying to force a "close enough" O-ring into place can result in pinched seals or continued leaking, which can waste expensive shielding gas or cause coolant messes. By choosing the correct part number, you ensure that your equipment operates exactly as the manufacturer intended.

Installation is typically straightforward. Simply remove the old, worn O-ring, clean the groove of any debris, and seat the new 488157 O-ring in place. A small amount of O-ring lubricant can help it slide into position without tearing. Keep a few of these in your spare parts kit so you are never stuck waiting on a small part to get a big job done. Trust in genuine ESAB parts to keep your shop running smoothly.
