Value Collection ZMSCQH70114 O-ring Dash 114 Nbr 70A

Product Description

The VALUE COLLECTION ZMSCQH70114 is a Dash 114 X-profile (quattro cross section) O-ring manufactured from Nitrile Butadiene Rubber (NBR). It measures 0.625 inches inside diameter, 0.813 inches outside diameter, and 0.0937 inches thick. The X-profile cross section provides four sealing contact points rather than two, reducing spiral twist and improving seal retention in dynamic and static applications. With a Shore A durometer of 70 and a working temperature range of -30 degrees F to 250 degrees F, this ring is suited for fluid and pneumatic sealing in HVAC, plumbing, and refrigeration service work. Licensed trade professionals and experienced service techs are the primary installers.

This O-ring is commonly used in static face-seal and low-speed dynamic groove applications involving oils, fuels, water, and common refrigerants within its rated temperature range. Typical installations include valve bodies, flare fittings, pump housings, and hydraulic connectors found in residential and light commercial HVAC systems, plumbing assemblies, and pool equipment. The Dash 114 sizing is a standard AS568 designation, making this a direct dimensional replacement for any Dash 114 groove spec. Sold in a package quantity of 100 units.

Compatibility

Dimensionally compatible with any standard AS568 Dash 114 O-ring groove calling for a 0.625 inch ID, 0.813 inch OD, and 0.0937 inch cross-section thickness in an X-profile or standard round-profile seat.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or qualified service professionals. Shut off all fluid supply, depressurize the system, and relieve any stored energy before removing the existing seal. Lightly lubricate the O-ring with a fluid compatible with NBR and the system media before seating to prevent tearing during assembly. Do not use petroleum-based lubricants in systems where compatibility with NBR has not been confirmed.
