Value Collection ZMSCH70216 Dash 216 Nbr O-ring 100-pack

Product Description

The VALUE COLLECTION ZMSCH70216 is a Dash 216 Nitrile Butadiene Rubber (NBR) O-ring with a 1.125-inch inside diameter, 1.375-inch outside diameter, and a 0.125-inch cross-section thickness. Also known as Buna-N, NBR is the most widely used elastomer in sealing applications. It delivers excellent resistance to petroleum-based fluids and hydraulic oils, along with strong compression set performance and notable tear and abrasion resistance. This O-ring carries a 70 Shore A hardness rating and a round cross-section profile. It is sold in a package of 100. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this type of seal routinely in fluid and gas systems.

This Dash 216 O-ring is suited for static and dynamic sealing applications involving petroleum products, hydraulic fluids, and similar media. Typical install scenarios include pipe fittings, valve stems, pump housings, compressor service, and general fluid system maintenance across residential and commercial settings. The rated temperature range of -40 degrees F to 250 degrees F makes it appropriate for a wide range of service environments. This O-ring meets SAE and MIL-Spec standards. It should not be stored in direct sunlight or near motors and other electrical equipment that may generate ozone, which can degrade the elastomer over time.

Compatibility

Designed as a standard Dash 216 O-ring replacement compatible with petroleum products and similar media in hydraulic, pneumatic, and general fluid sealing applications.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance technicians. Always depressurize and drain the system before removing the existing seal, and inspect the mating groove for damage or contamination before fitting the new O-ring. Lightly lubricate the O-ring with a compatible fluid or grease prior to installation to prevent tearing during seating. Do not install this O-ring in applications involving ozone-generating equipment or environments where the elastomer will be exposed to direct UV for extended periods.
