Value Collection ZMSCH70920 O-ring Dash 920 Nbr Pack 100

Product Description

The VALUE COLLECTION ZMSCH70920 is a Dash 920 O-ring made from Nitrile Butadiene Rubber (Buna-N), the most widely used elastomer in fluid sealing applications. It measures 1.475 inches inside diameter, 1.711 inches outside diameter, and 0.118 inches thick with a round cross section. Rated at 70 Shore A hardness, this O-ring delivers reliable compression set resistance along with strong tear and abrasion resistance. It is designed for use as an O-ring boss gasket on straight-thread tube fittings and performs across a working temperature range of -40 degrees F to 250 degrees F. Each package contains 100 pieces.

This O-ring is suited for hydraulic, pneumatic, and fluid-handling systems where exposure to petroleum-based fluids is expected. Common install scenarios include tube fitting assemblies, valve bodies, and hydraulic manifolds found in industrial, HVAC, plumbing, and mobile equipment applications. The Buna-N compound provides excellent resistance to petroleum products, lubricating oils, and fuels, making it a standard choice for both OEM assembly and maintenance repair work. Licensed plumbers, pipefitters, and industrial maintenance technicians regularly use Dash 920 O-rings in straight-thread boss port applications.

Compatibility

Designed as an O-ring boss gasket for straight-thread tube fittings. Compatible with petroleum products including lubricating oils, hydraulic fluids, and fuels. Meets SAE and MIL-Spec standards. Not FDA approved. Not recommended for use with ozone-generating environments or direct sunlight exposure during storage.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or hydraulic system technicians. Shut off and depressurize the system completely before removing or installing any O-ring. Lightly lubricate the O-ring with a compatible fluid prior to installation to prevent nicking or twisting during assembly. Do not store Buna-N O-rings near motors, electrical equipment, or in direct sunlight, as ozone and UV exposure degrade the elastomer over time.
