Value Collection ZMSCS70332 Silicone O-ring Dash 332

Product Description

The VALUE COLLECTION ZMSCS70332 is a round cross-section silicone O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial fluid systems. It measures 2.375 inches inside diameter, 2.75 inches outside diameter, and 0.1875 inches thick, conforming to the standard Dash 332 sizing. With a Shore A hardness of 70 and a rated temperature range of -80 degrees F to 450 degrees F, this ring handles wide thermal swings and sustained dry heat. Each package contains 10 rings. Licensed HVAC technicians, plumbers, and industrial maintenance technicians are the primary installers.

This O-ring is suited for applications that demand good resistance to weather, ozone, and broad temperature extremes. It performs in exposure to certain oils, chemicals, and solvents, though oil resistance is noted as limited. Typical install scenarios include sealing flanged connections, valve bodies, pump housings, and refrigerant-side fittings where silicone is the specified elastomer. It is not FDA approved and should not be selected for food-contact or potable-water applications where FDA compliance is required.

Designed as a standard Dash 332 silicone O-ring replacement for equipment requiring silicone elastomer seals in applications involving oils, chemicals, and solvents where a wide temperature range and dry heat resistance are priorities.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics. Always depressurize the system and shut off all fluid or refrigerant supply before removing or installing O-rings. Inspect the groove and mating surfaces for nicks or scoring before seating the new ring. Do not use petroleum-based lubricants with silicone O-rings unless confirmed compatible with both the ring material and the system fluid.
