Value Collection ZMSCQH70210 O-ring Dash 210 Nbr X-profile

Product Description

The VALUE COLLECTION ZMSCQH70210 is a Dash 210 O-ring with a quattro cross-section (X-profile) construction, manufactured from Nitrile Butadiene Rubber (NBR). It measures 0.75 inches inside diameter, 1.00 inch outside diameter, and 0.125 inches thick. The X-profile cross section provides four sealing lips instead of the standard round cross section, improving stability in the groove and reducing seal roll-out during dynamic applications. NBR material offers solid resistance to petroleum-based oils, fuels, and hydraulic fluids, making this O-ring a practical choice for fluid sealing in HVAC, plumbing, and general mechanical assemblies. Sold in packages of 100 units per order.

This O-ring is suited for static and dynamic sealing applications in residential and commercial systems where petroleum-based fluid compatibility is required. Typical uses include refrigerant line fittings, hydraulic connections, water supply components, and pump assemblies. The Dash 210 designation follows standard AS568 sizing, allowing direct substitution wherever a Dash 210 O-ring is specified. Plumbers, HVAC technicians, and mechanical contractors commonly stock this size for service and maintenance work.

Compatibility

Designed as a standard Dash 210 O-ring replacement suitable for static and dynamic sealing applications in HVAC, plumbing, hydraulic, and general mechanical systems requiring an NBR X-profile seal.

Installation Notes

Installation should be performed by a qualified technician following applicable codes such as the IPC or IFGC depending on the system served. De-pressurize and isolate the line or fitting before removing the old O-ring and installing the replacement. Lubricate the O-ring with a compatible fluid or assembly lubricant before seating it in the groove to prevent tearing during installation. Inspect the groove for damage or debris before installing the new seal.
