84W85 - ESAB 84W85 Replacement O-Ring for PT-31 Plasma Torch (Pack of 25)

Reliable Sealing for Plasma Systems

The ESAB 84W85 O-Ring is a critical replacement component designed specifically for the maintenance of plasma cutting torches, most notably the widely used PT-31 and PT-31XL series. In precision plasma cutting, the integrity of the gas seal is paramount. Even a microscopic leak or a slightly degraded seal can lead to a drop in gas pressure, irregular arc initiation, or poor cut quality. This O-ring features a precise 3/8-inch inner diameter, engineered to fit snugly within the torch head assembly to maintain the necessary airtight seal required for optimal plasma gas flow.

Supplied in a convenient bag of 25, this product is tailored for industrial environments, repair shops, and high-volume fabrication centers where equipment downtime must be minimized. Having a bulk supply of these essential seals ensures that maintenance personnel can perform routine service or emergency repairs immediately without waiting for individual parts to be shipped. The material composition is selected to withstand the thermal cycling and environmental conditions typical of plasma cutting operations, providing durability and resistance to drying or cracking over time.

Regular inspection and replacement of O-rings are standard preventive maintenance procedures recommended by equipment manufacturers. The 84W85 serves as a direct replacement for the OEM part, ensuring compatibility and performance standards are met. Whether you are refurbishing older L-Tec systems or maintaining a fleet of modern ESAB cutters using the PT-31 style torch, these O-rings provide the assurance of a secure fit and reliable operation.

By investing in the 25-pack configuration, procurement managers can reduce the administrative overhead of frequent small orders while ensuring that the welding and cutting floor remains operational. This product represents a small but vital link in the chain of quality production, safeguarding the efficiency of your plasma cutting equipment.
