Value Collection ZMSCQH70123 O-ring Dash 123 Nbr X-profile

Product Description

The VALUE COLLECTION ZMSCQH70123 is a Dash 123 O-ring with an X-profile (quattro) cross section, manufactured from Nitrile Butadiene Rubber (NBR). Unlike standard round-section O-rings, the X-profile cross section provides four sealing lobes, which reduces rolling and twisting in dynamic groove applications and improves seal stability under pressure cycling. With an inside diameter of 1.188 inches and an outside diameter of 1.375 inches, this ring fits standard Dash 123 groove geometry. Wall thickness is 0.0937 inches. NBR compound offers reliable resistance to petroleum-based oils, hydraulic fluids, and fuels, making it a common choice for plumbing, HVAC, and fluid-handling assemblies.

This O-ring is suited for static face-seal and dynamic reciprocating applications in residential and light commercial systems. Typical installation scenarios include pump housings, valve bodies, manifold fittings, and refrigerant or hydraulic line connections where the Dash 123 cross-sectional size is specified. NBR material is appropriate for service with water, air, petroleum oils, and many common refrigerants. Licensed plumbers, HVAC technicians, and fluid-system mechanics routinely stock Dash 123 rings for maintenance and repair work.

Compatibility

Designed to fit any application specifying a Dash 123 O-ring groove with an X-profile cross section, including pump assemblies, valve bodies, and fluid-line fittings that require an NBR seal material.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or fluid-system mechanics depending on the application. Always depressurize and isolate the system before removing or replacing any seal. Lubricate the O-ring with a compatible grease or fluid prior to seating to prevent tearing during assembly. Inspect the groove for burrs, corrosion, or damage that could compromise the seal before installing a new ring.
