Value Collection ZMSCQH70332 O-ring Dash 332 Nbr

Product Description

The VALUE COLLECTION ZMSCQH70332 is a Dash 332 O-ring with an X-profile (quattro) cross section, manufactured from Nitrile Butadiene Rubber (NBR). The inside diameter measures 2.375 inches, the outside diameter measures 2.750 inches, and the cross-section thickness is 0.1875 inches. The X-shaped cross section provides four sealing lobes instead of the standard round profile, improving sealing performance under dynamic conditions and reducing the risk of spiral failure in reciprocating applications. NBR construction offers resistance to petroleum-based fluids, hydraulic oil, and many common refrigerants, making this O-ring a practical choice for HVAC, plumbing, and fluid-handling assemblies where rubber seals are required.

This O-ring is suited for use in residential and commercial HVAC systems, refrigeration equipment, hydraulic assemblies, plumbing connections, and general industrial fluid-handling applications. The Dash 332 size designation follows AS568 standard sizing, making it a widely recognized replacement size for static and dynamic seal grooves requiring a 2.375-inch ID. Plumbers, HVAC technicians, and mechanical contractors typically stock Dash 332 seals for valve bodies, pump housings, manifold connections, and threaded pipe fittings where a reliable fluid seal is needed.

Compatibility

Designed as an OEM-style replacement or service seal for static and dynamic groove applications requiring an AS568 Dash 332 O-ring with an X-cross section profile.

Installation Notes

This O-ring is installed by qualified HVAC technicians, plumbers, and mechanical contractors. Before replacing any O-ring, shut off system pressure, depressurize the line, and isolate the fluid source. Inspect the seal groove for burrs, corrosion, or debris before seating the new O-ring, and apply a compatible lubricant to ease installation and prevent pinching. Do not use petroleum-based lubricants in systems where fluid compatibility with NBR has not been confirmed.
