Value Collection ZMSCH90130 O-ring Dash 130 Nbr 90 Duro

Product Description

The VALUE COLLECTION ZMSCH90130 is a Dash 130 nitrile butadiene rubber (NBR) O-ring designed for fluid sealing applications in plumbing, HVAC, and hydraulic systems. It measures 1.625 inches inside diameter, 1.813 inches outside diameter, and 0.094 inches thick with a round cross section. Rated at 90 durometer (extra hard), this O-ring handles a working temperature range of -40 degrees F to 250 degrees F. NBR is the most widely used elastomer for O-ring applications, offering excellent resistance to petroleum-based fluids, strong compression set performance, and good tear and abrasion resistance. Licensed plumbers, HVAC technicians, and hydraulic system technicians commonly specify this grade.

This O-ring is suited for use wherever petroleum-based fluids, oils, fuels, or hydraulic fluids are present. Typical applications include pump seals, valve stems, fittings, and fluid connectors in residential and light commercial mechanical systems. The extra-hard 90 durometer rating makes it appropriate for higher-pressure sealing environments where a softer compound would extrude or deform under load. Sold in packages of 50, it is a practical stocking item for shops and service vehicles. Note: this compound is not intended for use with ozone-generating environments, direct sunlight exposure, or near electric motors without proper shielding.

Key Features

• NBR compound provides excellent resistance to petroleum products, oils, and fuels

• Operating range of -40 degrees F to 250 degrees F suits a wide range of mechanical systems
• Round cross section, Dash 130 standard sizing for drop-in replacement use
• Meets SAE and MIL-Spec standards
• Sold in quantities of 50 per package, minimum order quantity of 1

Compatibility

Compatible with petroleum products and petroleum-based hydraulic fluids. Conforms to Dash 130 O-ring sizing per SAE and MIL-Spec standards. Should not be used with ozone-generating equipment or stored in direct sunlight.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system mechanics. Always depressurize and isolate the fluid circuit before removing or installing any O-ring. Inspect the groove and mating surfaces for burrs or corrosion before seating the new O-ring. Lightly lubricate with a compatible petroleum-based lubricant during installation to prevent rolling or tearing.
