Value Collection ZMSCS70022 Silicone O-ring Dash 022

Product Description

The VALUE COLLECTION ZMSCS70022 is a Dash 022 silicone O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial service work. It measures 1 inch inside diameter, 1.125 inches outside diameter, and 0.0625 inches thick with a round cross section. The silicone compound carries a Shore A hardness of 70 and is rated for service from -80 degrees F to 450 degrees F, making it well suited for systems that cycle through wide temperature ranges. Licensed technicians and tradespeople install these rings as replacement seals wherever the Dash 022 standard size is called out. Each order includes 50 pieces.

This O-ring is appropriate for residential and light commercial HVAC equipment, plumbing connections, pool and spa equipment, and general mechanical assemblies that require a flexible, heat-resistant seal. The silicone material provides good resistance to dry heat, weathering, and ozone exposure. It shows limited resistance to oils and should be confirmed compatible before use in heavy petroleum or fuel service. Typical applications include valve stems, pump housings, sensor ports, and fitting connections where a Dash 022 profile is specified.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or qualified service professionals. Always depressurize and isolate the system before removing or installing O-rings to prevent injury or fluid release. Inspect the seating groove for damage, burrs, or contamination before installing a new ring. Do not stretch the O-ring beyond the groove dimension during installation, and confirm chemical compatibility with system fluids before committing to silicone material in oil-heavy or fuel service environments.
