Value Collection ZMSCS70026 Silicone O-ring Dash 026 50 Pack

Product Description

The VALUE COLLECTION ZMSCS70026 is a silicone O-ring with a round cross section, sized at 1.25 inches inside diameter, 1.375 inches outside diameter, and 0.0625 inches thick. It carries a Dash 026 designation and a Shore A hardness of 70, placing it in the hard hardness range. Silicone compound provides a wide service temperature range from -80 degrees F to 450 degrees F, making it well suited for applications where extreme cold starts or sustained dry heat are factors. This O-ring ships in a package quantity of 50 units, supporting bench-stock and kit replenishment for maintenance operations.

This O-ring is used in plumbing, HVAC, and general mechanical assemblies where a static or low-dynamic sealing application calls for silicone rather than Buna-N or EPDM. Silicone is selected when the service environment involves wide temperature swings, ozone exposure, or weathering. It offers good resistance to oils, chemicals, and solvents in limited concentrations. Typical installation scenarios include access panels, sensor port seals, threaded fittings, and equipment covers in both residential and light commercial systems.

Compatibility

Designed as a standard Dash 026 silicone O-ring for static and low-dynamic sealing grooves in plumbing, HVAC, and general mechanical equipment requiring silicone compound compatibility.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified mechanical technicians depending on the system. Shut off and depressurize the system before removing the old O-ring. Inspect the groove for nicks or debris before seating the new ring. Do not use petroleum-based lubricants with silicone O-rings; use a silicone-compatible assembly lubricant if needed to ease installation.
