Value Collection ZMSCS70362 Silicone O-ring Dash 362 5-pack

Product Description

The VALUE COLLECTION ZMSCS70362 is a silicone O-ring with a round cross section, sized to Dash 362 standards. It measures 6.25 inches inside diameter, 6.625 inches outside diameter, and 0.1875 inches thick. With a Shore A hardness of 70, this O-ring is rated for a wide service temperature range of -80 degrees F to 450 degrees F, making it suitable for static sealing applications that see both extreme cold and sustained dry heat. Each package contains 5 rings. Plumbers, HVAC technicians, and industrial maintenance trades install this type of seal where a large-bore, chemically compatible silicone ring is required.

This O-ring is suited for use in systems where exposure to oils, chemicals, and solvents is present, though its oil resistance is limited and should be confirmed against the specific fluid media before installation. Its silicone compound provides good weather and ozone resistance, making it a common choice for outdoor-rated equipment, air-handling systems, and process piping that operates across a broad temperature range. It is supplied in white and is not FDA approved for food-contact applications.

Installation Notes

Always de-pressurize and isolate the system before replacing O-rings. Clean the gland groove of debris, old sealant, and residual lubricant before seating the new ring. Apply a compatible O-ring lubricant to ease installation and reduce risk of tearing the seal. Verify fluid and temperature compatibility with silicone compound before finalizing the installation.
