Value Collection ZMSCH70360 O-ring Dash 360 Nbr 70 Duro 5pk

Product Description

The VALUE COLLECTION ZMSCH70360 is a Dash 360 Nitrile Butadiene Rubber (NBR/Buna-N) O-ring with a 5.875-inch inside diameter, 6.25-inch outside diameter, and a 0.1875-inch round cross section. Rated at 70 durometer (Hard), this O-ring delivers excellent resistance to petroleum-based fluids, strong compression set performance, and solid tear and abrasion resistance. The part is sold in a pack of 5 and is suited for plumbing, hydraulic, pneumatic, and industrial sealing applications where contact with petroleum products is expected. HVAC, plumbing, and industrial maintenance technicians commonly install this ring as a static or dynamic face seal.

This O-ring is appropriate for residential and commercial sealing applications involving petroleum-based media, oils, fuels, and hydraulic fluids. Its temperature range of -40 degrees F to 250 degrees F makes it viable across a broad range of service conditions. Buna-N is the most widely used O-ring elastomer in trade work and serves well in valve bodies, pump housings, pipe unions, and fluid-system fittings. This ring should not be stored in direct sunlight or near motors or other electrical equipment that may generate ozone, as ozone degrades NBR compounds over time.

Key Features

• 70 durometer hardness rating provides a firm seal with reliable compression set performance
• Round cross section at 0.1875 inches fits standard Dash 360 O-ring grooves
• Operating range of -40 degrees F to 250 degrees F covers most HVAC and plumbing service conditions
• Meets SAE and MIL-Spec standards
• Pack of 5 units per order

Compatibility

Designed as a standard Dash 360 O-ring replacement compatible with petroleum-based fluid systems including hydraulic, pneumatic, and general plumbing assemblies that accept a 5.875-inch ID round-cross-section seal.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance mechanics. Always depressurize and de-energize the system before removing or installing any O-ring seal. Lubricate the O-ring lightly with a compatible petroleum-based or system-appropriate lubricant before seating to prevent tearing during assembly. Inspect the groove for burrs or damage before installation to ensure a proper seal.
