Ever-tite 320GSKBUX O-ring 2 Inch Id Nitrile Square

Product Description

The EVER-TITE COUPLING PRODUCTS 320GSKBUX is a Dash 320 square-cross-section O-ring designed for sealing applications in fluid and pneumatic systems. Made from Nitrile Butadiene Rubber (Buna-N), this ring measures 2 inches inside diameter, 2.656 inches outside diameter, and 5/16 inches thick. Its square cross-section provides increased sealing surface contact compared to round-profile rings, making it well-suited for static face-seal and groove applications. Rated for service between -40 degrees F and 212 degrees F, it is compatible with petroleum-based fluids. Licensed plumbers, HVAC techs, and industrial maintenance technicians commonly specify this ring for pump, valve, and fitting assemblies.

This O-ring fits residential and commercial applications wherever a Dash 320 square-profile seal is called for. Typical use cases include pump housings, pipe unions, valve bodies, and hydraulic or pneumatic fittings that handle petroleum products or similar media. The Buna-N compound resists oil, fuel, and many hydraulic fluids, making it a standard choice in plumbing, HVAC refrigerant-adjacent assemblies, and light industrial fluid handling. Each package contains one ring, allowing single-unit stocking or replacement.

Compatibility

Compatible with petroleum products and similar media. Designed as an OEM-style replacement or maintenance seal for any application requiring a Dash 320 square-cross-section Buna-N O-ring in pump, valve, or fitting assemblies.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance technicians. Always depressurize and de-energize the system and relieve all fluid pressure before removing old seals or installing new ones. Inspect the sealing groove for burrs, corrosion, or debris and clean thoroughly before seating the ring. Avoid using petroleum-based lubricants not compatible with Buna-N compounds when installing; use only approved O-ring lubricants.
