Value Collection ZMSCH70MD013 O-ring Dash 013 Nbr 25-pack

Product Description

The VALUE COLLECTION ZMSCH70MD013 is a Dash 013 O-ring manufactured from Buna-N (Nitrile Butadiene Rubber), one of the most widely used elastomers in fluid-sealing applications. It measures 0.438 inches inside diameter, 0.563 inches outside diameter, and 0.0625 inches thick, with a round cross section. Shore hardness is rated at 70, placing it in the hard category for positive compression set and resistance to extrusion under system pressure. This O-ring is sold in a package of 25 and is installed by HVAC technicians, plumbers, and hydraulic system mechanics wherever petroleum-based fluid or gas connections require a reliable face or radial seal.

This O-ring is suited for use with petroleum products, hydraulic oils, fuels, and similar media in residential and commercial service environments. Common applications include valve stems, fittings, pump housings, refrigerant-side connections using compatible media, and general plumbing assemblies. Its temperature range of -40 degrees F to 250 degrees F covers most mechanical room and field-service conditions. Each package contains 25 O-rings, making it appropriate for service stock or multi-unit repair calls.

Key Features

• Buna-N (Nitrile Butadiene Rubber) construction with excellent resistance to petroleum products and hydraulic fluids
• Shore hardness of 70 for strong compression set and abrasion resistance
• Operating temperature range of -40 degrees F to 250 degrees F
• Round cross section, Dash 013 designation for standard groove fitment
• Tear and abrasion resistant — suitable for dynamic and static sealing applications
• Packaged in quantities of 25 for efficient service stock management

Compatibility

Designed for use with petroleum products and compatible media in standard Dash 013 O-ring grooves across HVAC, plumbing, and hydraulic applications.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or hydraulic system mechanics. Always depressurize and shut off the fluid or gas supply before removing or replacing an O-ring. Inspect the mating groove for burrs or debris before seating the new ring. Do not store unused O-rings in direct sunlight or near motors and other electrical equipment that may generate ozone, as this degrades Buna-N material over time.
