Value Collection ZMSCS70023 Silicone O-ring Dash 023 50pk

Product Description

The VALUE COLLECTION ZMSCS70023 is a silicone O-ring with a round cross section, designed for static and dynamic sealing applications across HVAC, plumbing, and industrial systems. It measures 1.0625 inches inside diameter, 1.1880 inches outside diameter, and 0.0625 inches thick, conforming to Dash 023 sizing. With a hardness rating of 70 Shore A, this ring holds its shape under compression. The wide service temperature range of -80 degrees F to 450 degrees F makes it suited for high-heat and cold-environment applications. Licensed technicians and maintenance professionals use these rings in equipment servicing where thermal stability and dry heat resistance are required.

This O-ring is appropriate for use in residential and commercial HVAC systems, plumbing assemblies, and fluid-handling equipment where exposure to oils, chemicals, or solvents is limited. It is recommended for applications requiring good weather and ozone resistance and a wide operating temperature range. It is not recommended for applications with prolonged heavy oil exposure. Each package contains 50 rings, making it practical for service vans and shop stock. The minimum order quantity is 1 package.

Compatibility

Designed as a standard Dash 023 silicone O-ring replacement suitable for sealing grooves and fittings requiring a 1.0625-inch inside diameter and 0.0625-inch cross section thickness in HVAC, plumbing, and general mechanical assemblies. Compatible with oils, chemicals, and solvents at limited exposure levels.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or qualified maintenance professionals. Depressurize and de-energize the system before replacing any O-ring. Inspect the sealing groove for damage or debris before seating the new ring. Avoid overstretching the O-ring during installation, as silicone material has limited elongation tolerance compared to other elastomers.
