OVERVIEW

Industrial Grade Sealing Solution

The ESAB 86W75 O-Ring is a critical maintenance component designed for precision sealing in industrial welding environments. Manufactured from high-quality Buna-N (Nitrile) rubber, this O-ring is engineered to resist the degrading effects of petroleum-based oils, hydraulic fluids, and water, making it an industry standard for general-purpose sealing applications. With a 70 Durometer (Shore A) hardness rating, it offers the ideal balance between flexibility for easy installation and rigidity to resist extrusion under pressure.

Maintenance professionals understand that the integrity of gas regulation and fluid control systems relies heavily on the quality of their seals. This specific O-ring features an Inner Diameter (ID) of 0.114 inches and a Cross Section (CS) of 0.070 inches, corresponding to the standard AS568-006 size. These precise dimensions are crucial for maintaining system pressure and preventing hazardous leaks in regulators, torches, and other welding apparatus. The Buna-N material ensures a long service life within a temperature range typically spanning from -40°F to +250°F, covering most standard shop environments.

Stocking genuine replacement parts like the 86W75 ensures that your equipment remains compliant with manufacturer specifications. Whether performing routine preventative maintenance or addressing an unexpected failure, using the correct material and size specification is non-negotiable for safety and performance. This component is suitable for use in various ESAB and Victor equipment assemblies where a reliable static or dynamic seal is required.

FAQ

This O-ring is made from Buna-N (Nitrile) rubber, which is standard for general-purpose sealing due to its oil and fuel resistance.

The O-ring has an Inner Diameter (ID) of 0.114 inches and a Cross Section (width) of 0.070 inches.

It has a hardness of 70 Durometer (Shore A), which is the standard hardness for most static and dynamic sealing applications.

While Buna-N is compatible with many gases, always check your equipment's specific service manual for oxygen compatibility requirements, as some high-pressure oxygen applications require specific materials like Viton or EPDM.

Yes, this is a genuine ESAB/Victor replacement part, ensuring correct fitment and material specifications.

If you notice gas leaks, visible cracking, flattening of the O-ring (compression set), or if the rubber feels brittle, it should be replaced immediately.

Buna-N O-rings typically operate effectively between -40°F and +250°F (-40°C to +120°C).

Yes, this part number (86W75) is commonly used in Victor and ESAB gas equipment. Check your parts diagram to confirm.
