Value Collection ZMSCS70213 Silicone O-ring Dash 213

Product Description

The VALUE COLLECTION ZMSCS70213 is a round cross-section silicone O-ring sized to Dash 213 standards. It measures 0.921 inches inside diameter, 1.188 inches outside diameter, and 0.125 inches thick. With a Shore A hardness of 70 and a working temperature range of -80 degrees F to 450 degrees F, this O-ring is suited for static and dynamic sealing applications where wide temperature swings, dry heat exposure, and ozone or weathering resistance are primary concerns. Plumbers, HVAC technicians, and mechanical contractors install this type of seal in fluid-handling assemblies, pneumatic fittings, and process equipment requiring reliable seating across extreme thermal cycles.

This O-ring is appropriate for use in residential and light commercial plumbing, HVAC refrigerant-side fittings, chemical processing lines, and general industrial assemblies. It performs well in environments exposed to oils, certain chemicals, and solvents where silicone compounds retain elasticity. Its white color aids visual inspection during installation and maintenance. The package quantity is 100 pieces, making it practical for stocking service trucks or shop inventory.

Compatibility

Designed as a standard Dash 213 O-ring replacement for use in any system or fitting that specifies a Dash 213 silicone seal with a 0.921 inches ID and 0.125 inches cross-section thickness.

Installation Notes

Installation should be performed by a qualified technician following applicable plumbing, HVAC, or mechanical codes. Depressurize and drain the system before replacing any O-ring seal. Inspect the groove for nicks, burrs, or debris before seating the new ring. Avoid twisting or rolling the O-ring during installation, as spiral set will reduce service life and cause premature leakage.
