85W11 - ESAB 85W11 Replacement O-Ring for TIG Torches (.114 ID x .070) - 10 Pack

Technical Overview of the ESAB 85W11 O-Ring

The ESAB 85W11 is a specialized sealing component designed for precision fitment in TIG welding torches, specifically within the Heliarc product line. This O-ring features an Inner Diameter (ID) of 0.114 inches and a cross-sectional width of 0.070 inches. These dimensions are critical for establishing a hermetic seal within the torch assembly, typically at the back cap or gas lens interface, ensuring that shielding gas is directed efficiently through the nozzle without leakage.

Manufactured from high-grade elastomeric materials, these O-rings are engineered to withstand the thermal cycling and environmental conditions present in industrial welding operations. The material composition resists hardening and cracking over time, which are common failure modes for inferior seals exposed to residual heat and ozone. Maintaining the integrity of these seals is paramount for process stability; even minor degradation can introduce atmospheric contamination into the weld pool.

This product is supplied as a bulk pack containing 10 units. For MRO (Maintenance, Repair, and Operations) managers, this packaging configuration supports efficient inventory control and ensures that technicians have immediate access to replacement parts during routine maintenance intervals. The 85W11 is a direct replacement part, ensuring full compatibility with OEM specifications for ESAB equipment requiring this specific geometry.

Specifications and Compatibility

Correct identification of O-ring size is essential for proper installation. The 0.114" x 0.070" geometry is a standard size for specific internal torch connections. Users should verify the part number against their equipment's exploded view diagram to ensure correct fitment. This component plays a vital role in the gas delivery system, directly influencing the flow rate and laminar characteristics of the shielding gas.
