Value Collection ZMSCH90036 O-ring Dash 036 Nbr 90D 50-pack

Product Description

The VALUE COLLECTION ZMSCH90036 is a Dash 036 nitrile butadiene rubber (Buna-N) O-ring sold in a pack of 50. It measures 2.375 inches inside diameter, 2.5 inches outside diameter, and 0.0625 inches (1/16 inch) thick with a round cross-section. Rated at 90 durometer, this is an extra-hard compound that delivers excellent compression set resistance along with strong tear and abrasion resistance. The temperature range spans -40 to 250 degrees F, making it a reliable choice across a wide range of fluid-sealing applications. Meets SAE and MIL-Spec standards.

Buna-N is the most widely used O-ring elastomer in trade and industrial work. This ring is suited for sealing against petroleum-based fluids including hydraulic oils, fuels, and lubricants. Typical applications include hydraulic cylinders, pneumatic fittings, pump housings, and valve bodies in HVAC, plumbing, and fluid-power systems. The 50-piece pack is well suited for service technicians who stock consumables for repetitive seal replacement. Note: this compound should not be stored in direct sunlight or near motors and other electrical equipment that may generate ozone.

Compatibility

Compatible with petroleum-based products including hydraulic oils, fuels, and lubricants. Designed as a standard Dash 036 O-ring replacement for use in hydraulic, pneumatic, and fluid-sealing assemblies where a 90-durometer Buna-N compound is specified.

Installation Notes

O-ring replacement is performed by plumbers, HVAC technicians, and fluid-power mechanics. Always depressurize and drain the system before removing any fitting or valve containing an O-ring. Inspect the groove and mating surfaces for nicks or corrosion before seating the new ring. Lightly lubricate the O-ring with a compatible petroleum-based grease prior to installation to ease seating and reduce the risk of tearing.
