Value Collection ZMSCQH70217 O-ring Dash 217 Nbr

Product Description

The VALUE COLLECTION ZMSCQH70217 is a Dash 217 O-ring with an X-profile (quattro) cross section, manufactured from Nitrile Butadiene Rubber (NBR). NBR compound provides reliable resistance to petroleum-based oils, fuels, and hydraulic fluids, making this O-ring a practical choice for sealing applications across HVAC, plumbing, and fluid-handling systems. The inside diameter measures 1.188 inches, outside diameter measures 1.438 inches, and cross-section thickness is 0.125 inches. The X-profile cross section reduces spiral twist during installation and improves sealing contact compared to a standard round cross section.

This O-ring suits residential and light commercial applications where a Dash 217 standard size is required. Typical use cases include pump shaft seals, valve stems, refrigerant service ports, hydraulic fittings, and fluid connectors in HVAC and plumbing assemblies. The NBR material handles moderate temperature ranges and is compatible with water, mineral oil, and many common refrigeration oils. Each package contains 50 pieces, making it practical for service vans and shop stock.

Installation Notes

O-rings of this type are installed by licensed plumbers, HVAC technicians, and hydraulic system technicians. Always depressurize and isolate the system before removing or installing sealing components. Lightly lubricate the O-ring with a compatible lubricant prior to installation to prevent tearing and to seat it evenly. Inspect the mating groove for burrs or damage before installation, as surface defects are a leading cause of seal failure.
