Value Collection ZMSCH90215 O-ring Dash 215 Nbr 90 Duro 50pk

Product Description

The VALUE COLLECTION ZMSCH90215 is a Dash 215 nitrile butadiene rubber (NBR) O-ring designed for static and dynamic sealing applications across plumbing, HVAC, hydraulic, and general industrial systems. It measures 1.63 inches inside diameter with a 0.125 inch cross-section thickness and carries a 90 durometer hardness rating, placing it in the extra-hard category. The NBR compound delivers excellent resistance to petroleum-based fluids, fuels, and lubricants, making it a go-to choice for technicians who need a reliable, widely stocked elastomer seal. Each package contains 50 O-rings.

This O-ring is suited for residential and commercial applications wherever a Dash 215 seal is called for, including valve stems, pump housings, hydraulic fittings, and refrigeration service ports. The NBR material performs across a wide temperature range of -40 to 250 degrees F, supporting use in both low-temperature refrigeration environments and moderate-heat hydraulic or fuel systems. HVAC techs, plumbers, and industrial maintenance professionals routinely stock this dash size for field repairs and preventive maintenance work.

• Meets SAE and MIL-Spec standards
• Round cross section; black color; sold in a 50-piece package
• Store away from direct sunlight, ozone sources, and electrical motors to preserve elastomer integrity

Compatibility

Compatible with petroleum products and petroleum-based fluids. Designed as a standard Dash 215 replacement O-ring for any application specifying NBR material at this dash size. Not FDA approved; not recommended for use with strong acids, ketones, or ozone-generating environments.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system mechanics. Always depressurize and isolate the system before removing or replacing O-rings. Lightly lubricate the O-ring with a compatible fluid — such as a petroleum-based lubricant — before seating to prevent tearing during assembly. Do not store unused O-rings near motors, electrical equipment, or direct sunlight, as ozone and UV exposure degrade NBR elastomers over time.
