Value Collection ZMSCV70202 Viton O-ring Dash 202 25-pack

Product Description

The VALUE COLLECTION ZMSCV70202 is a Dash 202 Viton (fluoroelastomer) O-ring sold in a package of 25. It measures 0.25 inches inside diameter, 0.50 inches outside diameter, and 0.125 inches thick with a round cross section. Rated at 70 Shore A hardness, this O-ring handles service temperatures from -15 degrees F to 400 degrees F. Its fluoroelastomer compound provides low compression set, high-temperature resistance, and good resistance to petroleum products. HVAC technicians, plumbers, and industrial service professionals use it for static and dynamic sealing in fluid and gas systems.

This O-ring is well suited for residential and commercial HVAC, plumbing, refrigeration, and general industrial applications where petroleum-based fluids, high temperatures, or vacuum service conditions are present. The Dash 202 designation is a standard sizing reference that crosses into a wide range of valve, fitting, pump, and manifold applications. Its low gas permeability also makes it appropriate for low-pressure gas and vacuum service lines.

Installation Notes

Installation should be performed by a qualified HVAC technician, plumber, or industrial mechanic. Always depressurize and isolate the system before removing or installing O-rings. Inspect the groove and mating surfaces for nicks or corrosion before seating the new O-ring. Avoid twisting or stretching the O-ring during installation; use a compatible lubricant where the application and fluid compatibility allow.
