Value Collection ZMSCH70282 O-ring Dash 282 Nitrile 16in Id

Product Description

The VALUE COLLECTION ZMSCH70282 is a Dash 282 O-ring manufactured from Buna-N (nitrile butadiene rubber), the most widely used elastomer in sealing applications. It measures 16 inches inside diameter, 16.25 inches outside diameter, and 0.125 inches thick with a round cross section. Rated at 70 Shore A hardness, this O-ring delivers reliable sealing across a working temperature range of -40 degrees F to 250 degrees F. It is suited for use in hydraulic, pneumatic, and fluid-transfer systems where contact with petroleum-based media is expected. Plumbers, pipefitters, and industrial maintenance technicians commonly install this size in large-bore assemblies and flanged connections.

This O-ring is appropriate for residential and commercial applications involving petroleum-product-compatible sealing. Typical install scenarios include pipe flanges, pump housings, valve bodies, and large-diameter fittings where a standard Dash 282 cross-section profile is required. It meets SAE and MIL-Spec standards, making it suitable for demanding mechanical and fluid-system environments. Compatible materials include petroleum products and petroleum-based hydraulic fluids. Each package contains 2 O-rings, and the minimum order quantity is 1 package.

Key Features

• Buna-N (nitrile butadiene rubber) construction offers excellent resistance to petroleum products
• 70 Shore A hardness rating provides reliable compression set and dimensional stability under load
• Round cross section conforms to Dash 282 standard sizing for consistent groove fitment
• Operating range of -40 degrees F to 250 degrees F suits a wide range of service conditions
• Meets SAE and MIL-Spec standards
• Good tear and abrasion resistance for long service life in dynamic and static sealing applications

Compatibility

Designed as a standard Dash 282 O-ring replacement compatible with petroleum-product service environments; verify groove dimensions against the 16-inch ID, 16.25-inch OD, and 0.125-inch cross-section specification before installation. Not FDA approved. Store away from direct sunlight, motors, and ozone-generating electrical equipment.

Installation Notes

Plumbers, pipefitters, or industrial mechanics typically install large-bore O-rings of this size. Shut down and depressurize the system completely before disassembly and seal replacement. Inspect the mating groove for burrs, corrosion, or deformation prior to seating the new O-ring. Lightly lubricate the O-ring with a compatible petroleum-based or system-fluid lubricant during installation to prevent rolling or tearing during assembly.
