Value Collection ZMSCQH70127 O-ring Dash 127 Nbr 70A

Product Description

The VALUE COLLECTION ZMSCQH70127 is a Dash 127 O-ring with an X-profile cross section, manufactured from Nitrile Butadiene Rubber (NBR) with a 70 Shore A durometer hardness rating. It measures 1.438 inches inside diameter, 1.625 inches outside diameter, and 0.094 inches thick. The X-shaped cross section provides four-lobed sealing contact, which improves stability in dynamic and static applications compared to a standard round cross section. This O-ring is suited for use in fluid and pneumatic systems across HVAC, plumbing, and general mechanical assemblies where moderate pressure and broad temperature range sealing is required.

This O-ring is appropriate for static and low-speed dynamic sealing in residential and commercial systems. Typical applications include pump housings, valve bodies, manifolds, and pipe fittings that operate within a temperature range of -30 degrees F to 250 degrees F. NBR material provides reliable resistance to petroleum-based oils, hydraulic fluids, and water, making it a practical choice for plumbing, HVAC refrigerant-adjacent assemblies, and light industrial fluid handling. Sold in a package quantity of 25 units.

Compatibility

Designed as an OEM-style replacement or service O-ring for Dash 127 groove specifications in static and dynamic sealing applications across HVAC, plumbing, and general mechanical equipment.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or mechanical service professionals. Depressurize and isolate the system completely before removing the existing O-ring. Inspect the groove and mating surfaces for nicks, scoring, or debris before installing the new O-ring. Apply a compatible lubricant to the O-ring surface to ease installation and reduce the risk of tearing during assembly.
