Value Collection ZMSCH70MD213 O-ring Dash 213 Nbr 10-pack

Product Description

The VALUE COLLECTION ZMSCH70MD213 is a Dash 213 nitrile butadiene rubber (NBR) O-ring with a 15/16-inch inside diameter, 1-3/16-inch outside diameter, and 1/8-inch cross-section thickness. NBR is the most widely used O-ring elastomer in trade applications, offering excellent resistance to petroleum-based fluids, strong compression set performance, and solid tear and abrasion resistance. Hardness is rated at 70 Shore A, placing it in the hard range for reliable sealing under pressure. Each package contains 10 O-rings. This part is installed by licensed plumbers, HVAC technicians, and mechanical contractors working on fluid and gas systems.

The ZMSCH70MD213 is suited for static and dynamic sealing applications involving petroleum products, hydraulic fluids, and similar media. Its operating temperature range of -40 degrees F to 250 degrees F makes it appropriate for a broad range of residential and light commercial mechanical systems. Common install scenarios include pump housings, valve bodies, fittings, and equipment flanges where a standard Dash 213 cross-section O-ring is specified. This O-ring should not be stored in direct sunlight or near motors and other electrical equipment that generate ozone, as ozone degrades NBR compounds over time.

Key Features

• Strong compression set, tear resistance, and abrasion resistance
• Sold in a 10-piece package; minimum order quantity of 1 package

Compatibility

Designed as a standard Dash 213 O-ring replacement compatible with petroleum-based fluid systems and hydraulic applications where NBR elastomer is the specified material.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system mechanics. Before replacing an O-ring, shut off fluid supply and depressurize the system completely. Clean the groove and mating surfaces before seating the new O-ring to ensure a leak-free seal. Do not store unused O-rings near motors, ozone-generating equipment, or in direct sunlight, as this degrades NBR material.
