Product Description

The VALUE COLLECTION ZMSCH70146 is a Dash 146 O-ring made from Nitrile Butadiene Rubber (Buna-N), the most widely used elastomer in sealing applications. It measures 2.625 inches inside diameter, 2.813 inches outside diameter, and 0.0937 inches thick with a round cross section. Hardness is rated at 70 Shore A, placing it in the hard range for reliable compression set performance. This O-ring delivers excellent resistance to petroleum-based fluids, strong tear and abrasion resistance, and dependable sealing across a wide service temperature range of -40 to 250 degrees F. Sold in a package of 50 units.

This O-ring is used across HVAC, plumbing, hydraulic, and pneumatic systems where sealing against petroleum-based oils, fuels, and lubricants is required. It is appropriate for static and dynamic sealing applications in residential and commercial equipment. Technicians and maintenance professionals across multiple trades install Dash 146 Buna-N O-rings in fittings, valves, pumps, and fluid-handling assemblies.

Installation Notes

Depressurize and drain the system before removing or installing O-rings. Inspect the gland and sealing surfaces for nicks, scoring, or contamination that could compromise the seal. Apply a light coat of compatible lubricant to ease installation and prevent nicking during assembly. Store unused O-rings away from direct sunlight, ozone sources, and electrical equipment that may generate ozone, as these conditions accelerate elastomer degradation.
