Value Collection ZMSCS70032 Silicone O-ring Dash 032

Product Description

The VALUE COLLECTION ZMSCS70032 is a silicone O-ring with a round cross section, supplied in a pack of 25. It measures 1.875 inches inside diameter, 2.000 inches outside diameter, and 0.0625 inches thick, conforming to Dash 032 sizing. Rated at 70 Shore hardness, this O-ring handles a working temperature range of -80 degrees F to 450 degrees F, making it a dependable sealing solution for applications that demand wide thermal tolerance and dry heat resistance. Plumbers, HVAC technicians, and mechanical trade professionals install these to maintain fluid and gas seals in systems where standard rubber compounds fall short.

This O-ring is suited for residential and light commercial applications involving oils, chemicals, and solvents where silicone's weather and ozone resistance is an advantage. Typical install scenarios include sealing joints in HVAC components, plumbing fixtures, fluid handling equipment, and general mechanical assemblies. The Dash 032 sizing is a widely referenced standard dimension used across many system types. Note that this compound offers limited oil resistance, so it should be selected with that constraint in mind for oil-heavy environments.

Key Features

• Silicone material provides good weather and ozone resistance across a broad temperature range
• Operating range of -80 degrees F to 450 degrees F suits demanding thermal environments
• Round cross section for consistent sealing contact and reliable compression
• 70 Shore hardness rated Hard for firm, stable sealing performance
• Compatible with oils, chemicals, and solvents in appropriate concentrations
• Dash 032 standard sizing for straightforward cross-reference and replacement

Compatibility

Designed as a standard Dash 032 O-ring replacement for systems and assemblies requiring silicone sealing compounds rated for wide temperature range and chemical exposure service.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified mechanical trades depending on the application. Always depressurize and de-energize the system before removing or installing sealing components. Inspect the groove seat for burrs or corrosion before seating the new O-ring, and apply a compatible lubricant to ease installation without compromising the seal. Follow applicable codes including IPC or IFGC as relevant to the system type.
