85W10 - ESAB 85W10 Replacement O-Ring Kit - .239 ID x .070 (10-Pack)

Reliable Sealing for Precision Welding

The ESAB 85W10 O-Ring is a critical maintenance component designed to ensure the integrity of your welding or cutting torch's gas distribution system. In the high-stakes environment of industrial welding and plasma cutting, even the smallest leak can lead to significant performance issues, ranging from erratic arcs to contaminated welds. This O-ring is engineered to precise specifications, featuring an Inner Diameter (ID) of 0.239 inches and a Cross Section of 0.070 inches, ensuring a perfect fit for compatible ESAB equipment.

Gas leaks in a torch assembly are not just a safety hazard; they are a primary cause of porosity in welds and poor cut quality in plasma operations. By maintaining a tight seal, the 85W10 O-ring ensures that shielding gas or plasma gas flows exactly where it is needed—at the arc zone—without turbulence or pressure loss. This kit comes as a bag of 10, providing maintenance teams and operators with the necessary spares to perform routine service or emergency repairs without downtime.

Genuine ESAB Quality

Using genuine ESAB parts like the 85W10 guarantees material compatibility and dimensional accuracy. Generic O-rings may not withstand the thermal cycling and chemical exposure found in welding environments, leading to premature failure. These O-rings are manufactured from high-quality elastomers designed to resist hardening and cracking over time.

Maintenance Best Practices

Regular inspection of torch O-rings is recommended during consumable changes. If an O-ring appears flattened, cracked, or dry, it should be replaced immediately. A small amount of silicone lubricant (if specified by the torch manual) can help seat the O-ring properly and extend its lifespan. Keeping a 10-pack of 85W10 O-rings on hand is a proactive measure that supports continuous, high-quality production.
