Value Collection ZMSCV70208 Viton O-ring Dash 208 25-pack

Product Description

The VALUE COLLECTION ZMSCV70208 is a Dash 208 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications in systems that handle petroleum products, fuels, and high-temperature fluids. Measuring 0.625 inches inside diameter, 0.875 inches outside diameter, and 0.125 inches thick, this O-ring features a round cross section and a Shore A hardness of 70. The fluoroelastomer compound delivers strong resistance to petroleum-based media, low compression set, and reliable performance across a wide temperature range from -15 degrees F to 400 degrees F. Each package contains 25 pieces.

This O-ring is suited for plumbing, HVAC, hydraulic, and fuel-system applications where exposure to petroleum products, oils, or elevated operating temperatures is expected. The Dash 208 designation is a standard AS568 size, making it a common replacement seal in pumps, valves, fittings, and manifold assemblies found in both residential and commercial mechanical systems. It is also rated for vacuum service and exhibits low gas permeability, making it appropriate for sealed pneumatic and vacuum circuit connections.
