Product Description

The VALUE COLLECTION ZMSCH70FDA008 is a Dash 008 O-ring sold in a package of 25, manufactured from Buna-N (Nitrile Butadiene Rubber) with a white FDA-approved compound. It measures 0.188 inches inside diameter, 0.312 inches outside diameter, and 0.0625 inches thick with a round cross section. Hardness is rated at 70 Shore A. This O-ring is used across HVAC, plumbing, and fluid-handling applications where resistance to petroleum-based media is required. Installation is performed by HVAC technicians, plumbers, and equipment service professionals as a standard sealing component in fittings, valves, and mechanical assemblies.

This O-ring is suited for use with petroleum products and petroleum-based fluids. The Buna-N elastomer is the most widely used O-ring material in trade applications due to its broad chemical compatibility and reliable compression set. The white FDA-approved formulation makes it appropriate for systems where food-grade compliance is required. Operating temperature range spans -40 degrees F to 250 degrees F, covering most residential and light commercial HVAC and plumbing service conditions. Each package contains 25 O-rings, supporting both single-repair jobs and recurring service work.
