Value Collection ZMSCH90142 O-ring Dash 142 Nbr 90 Duro 50pk

Product Description

The VALUE COLLECTION ZMSCH90142 is a Dash 142 O-ring manufactured from Nitrile Butadiene Rubber (Buna-N), the most widely used elastomer in fluid sealing applications. It measures 2.375 inches inside diameter, 2.563 inches outside diameter, and 0.094 inches thick with a round cross section. The 90 durometer hardness rating places this in the extra-hard category, providing excellent compression set resistance along with strong tear and abrasion resistance. The temperature range spans -40 to 250 degrees F, making it suitable for a broad range of service conditions. Sold in a package quantity of 50 units, this O-ring is a standard choice for plumbers, pipefitters, and maintenance technicians working on fluid handling systems.

This O-ring is designed for use in petroleum-based fluid environments, including hydraulic systems, fuel lines, and general industrial plumbing assemblies. Its Buna-N construction delivers reliable resistance to petroleum products, oils, and fuels. It is commonly installed in valve bodies, pump housings, fittings, and cylinder assemblies where a firm, durable seal is required. The Dash 142 designation follows SAE and MIL-Spec standards, making it a recognizable, interchangeable size across a wide range of trade and industrial applications.

Compatibility

Compatible with petroleum products, oils, and fuels. Meets SAE and MIL-Spec standards for Dash 142 O-rings. Not recommended for exposure to direct sunlight, ozone, or environments generated by motors and electrical equipment during storage.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or hydraulic system technicians. Shut down and depressurize the system fully before removing or installing any O-ring seals. Lubricate the O-ring with a compatible fluid before seating to prevent nicking or tearing during assembly. Do not store unused O-rings in direct sunlight or near motors and other equipment that may generate ozone, as this degrades Buna-N material over time.
