Value Collection ZMSCQH70119 O-ring Dash 119 Nbr 70A

Product Description

The VALUE COLLECTION ZMSCQH70119 is a Dash 119 O-ring with an X-profile cross section manufactured from Nitrile Butadiene Rubber (NBR). It measures 15/16 inches (0.9380 inches) inside diameter, 1-1/8 inches (1.1250 inches) outside diameter, and 3/32 inches (0.0937 inches) thick. The 70 Shore A durometer rating places it in the hard range, making it well suited for dynamic and static sealing applications where resistance to petroleum-based fluids, hydraulic oils, and fuels is required. NBR compounds provide reliable performance in a working temperature range of -30 degrees F to 250 degrees F. Sold in a package of 50 pieces.

This O-ring is used across plumbing, HVAC, hydraulic, pneumatic, and general industrial sealing applications. The X-profile (quattro) cross section provides four sealing contact points rather than two, which reduces spiral twist in dynamic applications and improves stability in grooves compared to a standard round cross section. It is commonly installed by plumbers, pipefitters, HVAC technicians, and maintenance mechanics in fluid-handling systems, valve assemblies, pump housings, and manifold connections where an inch-series Dash 119 seal is specified.

Key Features

• X-profile cross section reduces spiral twist and improves groove stability in dynamic service
• Nitrile Butadiene Rubber construction resists petroleum oils, hydraulic fluids, and fuels
• 70 Shore A hardness rated Hard for positive sealing under pressure
• Wide temperature range: -30 degrees F to 250 degrees F
• Inch-series Dash 119 sizing for straightforward cross-reference and replacement
• Package of 50 pieces minimizes per-unit cost for service stock or batch installations

Compatibility

Designed as a standard inch-series Dash 119 O-ring replacement suitable for any groove or port machined to accept a Dash 119 cross-section seal per standard O-ring sizing conventions.

Installation Notes

Power down or depressurize the system completely before removing any seals or fittings. Clean the groove and mating surfaces thoroughly before seating the O-ring to prevent debris-caused leaks. Apply a compatible lubricant to the O-ring during assembly to ease installation and reduce the risk of cutting or rolling the seal. Verify the groove dimensions match Dash 119 specifications before installation to ensure proper compression and sealing.
