Value Collection ZMSCH90030 O-ring Dash 030 Nbr 90 Duro

Product Description

The VALUE COLLECTION ZMSCH90030 is a Dash 030 Buna-N (Nitrile Butadiene Rubber) O-ring rated at 90 durometer, designed for static and dynamic sealing applications across HVAC, plumbing, hydraulic, and pneumatic systems. It measures 1.625 inches inside diameter, 1.750 inches outside diameter, and 0.0625 inches thick with a round cross section. The extra-hard 90 durometer rating provides strong resistance to extrusion under pressure. The temperature range spans -40 to 250 degrees F, making it suitable for a wide range of fluid and gas sealing environments. Licensed tradespeople and maintenance technicians use this O-ring as a standard replacement seal in valves, fittings, pumps, and fluid-handling components.

This O-ring is well suited for use with petroleum-based fluids, hydraulic oils, fuels, and lubricants. It is commonly installed in HVAC refrigeration system components, plumbing valve packing assemblies, pump seals, and compressed air fittings. The Buna-N material offers excellent compression set resistance and tear and abrasion resistance, which makes it a dependable choice in high-cycle or high-vibration service environments. This item is packaged in a quantity of 100, making it appropriate for shop stock, fleet maintenance kits, and repeat service calls where multiple seals may be needed at once.

Installation Notes

Installation of O-rings should be performed by qualified tradespeople following applicable system service procedures. Always depressurize and de-energize the system before removing existing seals or fittings. Inspect the groove and mating surfaces for burrs or corrosion prior to installation. Lubricate the O-ring with a compatible fluid before seating to prevent tearing during assembly.
