Value Collection ZMSCS70154 Silicone O-ring Dash 154

Product Description

The VALUE COLLECTION ZMSCS70154 is a Dash 154 silicone O-ring with a round cross section, sold in a pack of 10. It measures 3.75 inches inside diameter and 3.938 inches outside diameter, with a thickness of 0.094 inches. The 70-durometer silicone compound delivers a working temperature range of -80 degrees F to 450 degrees F, making it well suited for sealing applications that demand wide thermal tolerance and dry heat resistance. HVAC technicians, plumbers, and mechanical service professionals use this O-ring where a reliable, heat-stable seal is required.

This O-ring is appropriate for use in HVAC systems, plumbing assemblies, pool and spa equipment, and general mechanical applications where exposure to wide temperature swings, weathering, or ozone is a concern. The silicone material offers good weather and ozone resistance and limited oil resistance. It is suitable for contact with certain oils, chemicals, and solvents in appropriate concentrations. Each package contains 10 O-rings, and the minimum order quantity is 1 package.

Installation Notes

Installation is typically performed by a licensed HVAC technician, plumber, or qualified mechanical technician. Always de-energize or shut off the system and relieve all pressure before replacing an O-ring. Inspect the groove and mating surfaces for nicks or contamination before seating the new O-ring, and apply a compatible lubricant to ease installation without damaging the sealing surface. Confirm that silicone is appropriate for the specific fluid and pressure conditions in the application before installation.
