Value Collection ZMSCTST008 O-ring Dash 008 Ptfe 50-pack

Product Description

The VALUE COLLECTION ZMSCTST008 is a rectangular cross-section PTFE (polytetrafluoroethylene) O-ring sized to the Dash 008 standard. It measures 0.202 inches inside diameter, 0.308 inches outside diameter, and 0.047 inches thick. PTFE construction gives this O-ring a wide service temperature range of -65 to 500 degrees F and strong chemical resistance, making it suitable for demanding fluid and gas sealing applications. Each package contains 50 pieces, sold at a minimum order quantity of one package. Plumbers, HVAC technicians, and maintenance professionals use this part wherever a compact, chemically resistant static seal is required.

This O-ring is used in residential and light commercial sealing applications including valve stems, fittings, manifolds, pumps, and instrumentation ports. Its small Dash 008 profile fits tight-clearance assemblies found in refrigeration components, plumbing connections, and pneumatic fittings. The medium hardness rating of 55 durometer provides reliable compression sealing without excessive deformation under normal clamping loads. PTFE material is particularly appropriate in environments involving aggressive chemicals, solvents, or extreme temperature swings where standard rubber O-rings would degrade.

Installation Notes

Installation should be performed by a qualified technician following applicable codes such as the IPC or IFGC depending on the system type. Always depressurize and isolate the line or assembly before removing or installing O-rings. Inspect the seating groove for burrs or debris that could damage the PTFE material during assembly. Avoid using sharp tools that may nick or cut the O-ring surface during placement.
