Value Collection ZMSCQH70024 X-profile O-ring Nbr Dash 024

Product Description

The VALUE COLLECTION ZMSCQH70024 is an X-profile (quattro cross-section) O-ring used to create static or dynamic fluid and gas seals in plumbing, HVAC, and general mechanical assemblies. It measures 1.125 inches inside diameter and 1.25 inches outside diameter with a 0.0625-inch thickness. The nitrile butadiene rubber (NBR) compound carries a Shore A durometer rating of 70, placing it in the hard hardness range. The X-profile cross section provides four sealing lips instead of the standard round profile, reducing spiral twist in dynamic groove applications. Licensed plumbers, pipefitters, and HVAC technicians commonly install this type of seal during valve rebuilds, pump service, and connection fitting repairs.

This O-ring is suited for residential and light commercial plumbing and HVAC applications where a reliable NBR seal is required. The dash 024 designation identifies its standard size within the AS568 O-ring sizing system, making it straightforward to cross-reference against other suppliers and OEM part lists. Its rated temperature window of -30 degrees F to 250 degrees F supports most hydronic, refrigeration accessory, and general fluid-handling service environments. The NBR compound offers solid resistance to petroleum-based oils, water, and common refrigeration lubricants encountered in trade service work.

Compatibility

Designed as an OEM-style replacement or service seal for valves, fittings, pumps, and mechanical assemblies requiring a dash 024 X-profile NBR O-ring with 1.125-inch inside diameter and 1.25-inch outside diameter.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. De-energize and depressurize the system fully before removing any component containing this seal. Lightly lubricate the O-ring with a compatible fluid or grease before seating it in the groove to prevent nicking or rolling during assembly. Inspect the groove for burrs or corrosion before installing the replacement seal.
