Value Collection ZMSCS70009 Silicone O-ring Dash 009 100 Pack

Product Description

The VALUE COLLECTION ZMSCS70009 is a Dash 009 silicone O-ring sized at 0.219 inches inside diameter, 0.344 inches outside diameter, and 0.0625 inches thick with a round cross section. Rated for continuous service from -80 degrees F to 450 degrees F, this O-ring is built for applications that demand a wide temperature range and solid dry heat resistance. The silicone compound also provides good weather and ozone resistance. It is supplied in a package quantity of 100 pieces, making it suitable for shop stock, service van inventory, or production line use. Licensed trades including HVAC technicians, plumbers, and mechanical contractors install these in sealing applications across fluid and gas systems.

This O-ring is used in residential and light commercial HVAC, plumbing, and fluid-handling assemblies where a small-diameter, high-temperature-capable seal is required. It is compatible with oils, chemicals, and solvents within its rated temperature range, though oil resistance is limited. Typical install scenarios include sealing fittings, valve stems, pump shafts, and access port caps. The Dash 009 designation is a standardized sizing reference widely recognized across HVAC, refrigeration, and plumbing service work, simplifying cross-referencing during field repairs or scheduled maintenance.

Installation Notes

Installation should be performed by a qualified technician familiar with the equipment being serviced. Depressurize and isolate the system before removing or replacing any O-ring seal. Inspect the groove and mating surface for nicks or contamination before seating the new O-ring. Do not stretch or twist the O-ring during installation, and verify full seating before returning the system to service.
