Value Collection ZMSCS70147 Silicone O-ring Dash 147 10pk

Product Description

The VALUE COLLECTION ZMSCS70147 is a Dash 147 silicone O-ring designed for sealing applications that demand wide temperature tolerance and reliable performance across a range of service conditions. With a 2.688-inch inside diameter, 2.875-inch outside diameter, and 0.0937-inch (3/32 inch) cross-section thickness, this round-profile ring seals static and dynamic joints in plumbing, HVAC, pool, and industrial equipment. 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 environments with dry heat cycling, wide seasonal swings, or ozone exposure. Each order ships as a package of 10 rings.

This O-ring is used in residential and commercial applications wherever a standard Dash 147 silicone seal is required. Typical install scenarios include pump housings, valve bodies, heat exchanger ports, filter canisters, and equipment access covers in HVAC, plumbing, and pool systems. The silicone material offers good weather and ozone resistance and handles moderate chemical and solvent exposure. It is not recommended as a primary seal in high-pressure oil service. Installers often keep a stock of Dash 147 rings on hand for service calls involving common pump and valve assemblies.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or pool service professionals depending on the application. Shut off and depressurize the system completely before removing the old ring or seating the new one. Clean the groove and mating surface of debris and old sealant before installation. Do not stretch or roll the O-ring over sharp edges, and avoid using petroleum-based lubricants with silicone compounds unless confirmed compatible with the system fluid.
