Value Collection ZMSCS70232 Silicone O-ring Dash 232 10-pack

Product Description

The VALUE COLLECTION ZMSCS70232 is a Dash 232 silicone O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial fluid systems. It measures 2.75 inches inside diameter, 3.0 inches outside diameter, and 0.125 inches thick, with a round cross section and a Shore 70 hardness rating. The silicone compound delivers a wide service temperature range from -80 degrees F to 450 degrees F, making it well suited for high-heat and outdoor environments where standard nitrile or EPDM compounds fall short. Licensed tradespeople and maintenance technicians install this part when replacing worn or damaged seals in piping, equipment housings, and valve assemblies. Each package contains 10 rings.

This O-ring is appropriate for residential and commercial applications where the sealing surface is exposed to dry heat, ozone, and weathering. The silicone material offers good resistance to a broad range of chemicals and solvents, though its oil resistance is limited. Typical installation scenarios include equipment flanges, pump covers, access panels, and threaded fittings where a Dash 232 cross-section seal is specified. Installers should confirm fluid media compatibility before use, particularly in oil-rich or fuel-contact environments where a different compound may be required.

• Round cross section with Shore 70 hardness for consistent sealing pressure
• Good resistance to weathering, ozone, and a broad range of chemicals and solvents
• Limited oil resistance — verify compatibility before use in oil or fuel contact applications
• White silicone compound; non-FDA approved
• Sold in a 10-ring package with a minimum order quantity of 1

Compatibility

Designed as a standard Dash 232 O-ring replacement for any application specifying a 2.75-inch ID, 3.0-inch OD, 0.125-inch thick round cross-section seal in silicone compound.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance mechanics. Always depressurize and isolate the system before replacing any O-ring seal. Inspect the groove and mating surfaces for nicks, burrs, or corrosion that could compromise the seal. Avoid over-stretching the ring during installation, and do not use sharp tools that may nick the sealing surface.
