Value Collection ZMSCS70008 Silicone O-ring Dash 008 100pk

Product Description

The VALUE COLLECTION ZMSCS70008 is a silicone O-ring with a round cross section, sized at 0.188 inches inside diameter, 0.313 inches outside diameter, and 0.0625 inches thick. It carries a Dash 008 designation and a durometer hardness of 70. Silicone construction gives this O-ring a working temperature range of -80 degrees F to 450 degrees F, making it well suited for high-heat and wide-temperature-swing applications. It also provides good resistance to weathering and ozone. Plumbers, HVAC technicians, and mechanical tradespeople use this O-ring in fluid and gas sealing applications where dry heat resistance and broad thermal tolerance are required.

This O-ring is appropriate for residential and light commercial mechanical systems where a small-diameter seal is needed. It is used in plumbing connections, HVAC equipment, pool and spa fittings, and general mechanical assemblies exposed to temperature extremes. The silicone material offers limited oil resistance but performs well against many chemicals and solvents. Sold in a package of 100, this O-ring is a practical stock item for service vans, maintenance facilities, and wholesale distribution counters serving trade professionals.

Installation Notes

O-ring installation should be performed by a qualified plumber, HVAC technician, or mechanical tradesperson. Always depressurize and drain the system, or de-energize electrical components, before replacing a seal. Inspect the O-ring groove and mating surface for damage or debris before seating the new ring. Note that this silicone compound offers limited oil resistance; verify chemical compatibility with the process fluid before installation.
