Value Collection ZMSCS70132 Silicone O-ring Dash 132

Product Description

The VALUE COLLECTION ZMSCS70132 is a silicone O-ring with a round cross section, sized to the Dash 132 standard. It measures 1.75 inches inside diameter, 1.938 inches outside diameter, and 0.094 inches thick. With a durometer hardness of 70 and a rated temperature range of -80 degrees F to 450 degrees F, this O-ring is suited for sealing applications that demand wide thermal tolerance and dry heat resistance. Silicone construction also provides good weather and ozone resistance. Licensed trades and maintenance technicians use this part as a sealing element in fluid, gas, and mechanical assemblies.

This O-ring fits static and dynamic sealing applications across HVAC, plumbing, pool, and general mechanical systems. It is appropriate where silicone elastomers are specified for high- or low-temperature exposure, outdoor weathering, or ozone-heavy environments. Note that silicone carries limited oil resistance, so it is not recommended for continuous petroleum-fluid immersion. The package contains 25 O-rings, suitable for service stock or batch replacement work on equipment with multiple identical seal points.

Key Features

Compatibility

Designed as a standard Dash 132 silicone O-ring for use in static or dynamic sealing applications where silicone elastomer and the Dash 132 dimension are specified. Compatible with oils, chemicals, and solvents as noted by the manufacturer, with limited oil resistance.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or mechanical service professionals depending on the application. Always depressurize the system and shut off fluid supply before replacing seals. Inspect the gland or groove for damage or contamination before seating the new O-ring. Do not use petroleum-based lubricants with silicone O-rings; use a silicone-compatible assembly lubricant if needed.
