Value Collection ZMSCS70137 Silicone O-ring Dash 137

Product Description

The VALUE COLLECTION ZMSCS70137 is a Dash 137 silicone O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial fluid systems. The round cross-section profile measures 2.0625 inches inside diameter, 2.25 inches outside diameter, and 0.0937 inches thick. Made from white silicone with a Shore A hardness of 70, this O-ring holds a seal across an operating range of -80 degrees F to 450 degrees F. Licensed technicians and pipefitters install these during equipment repair, valve service, and pump overhaul work where consistent sealing performance under thermal cycling is required.

This O-ring suits applications that demand wide temperature tolerance and good dry heat resistance. It performs well in environments with exposure to weather and ozone. Oil resistance is limited, so it is best suited for non-petroleum fluid paths or dry-heat service points. Typical uses include HVAC equipment fittings, water handling assemblies, and light chemical service connections where a silicone compound is specified by the equipment manufacturer. Each package contains 10 O-rings.

Key Features

• Operating range from -80 degrees F to 450 degrees F suits extreme thermal cycling environments
• Round cross-section profile ensures consistent compression and seal contact
• Shore A hardness of 70 rated as hard provides stable sealing under moderate mechanical load
• Good weather and ozone resistance extends service life in outdoor or exposed installations
• Compatible with oils, select chemicals, and solvents where silicone compounds are appropriate
• Packaged in quantities of 10 for bench stock and service van inventory

Compatibility

Designed as a standard Dash 137 O-ring replacement for any application calling out a Dash 137 silicone seal with a 2.0625 inches inside diameter and 0.0937 inches cross-section thickness.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or pipefitters. Depressurize and isolate the fluid circuit completely before removing the existing O-ring. Inspect the groove and mating surfaces for scoring or contamination before seating the replacement. Do not use petroleum-based lubricants with silicone O-rings; use a silicone-compatible assembly lubricant if needed.
