The V2.5X137 is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 137 mm (5.394 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 142 mm (5.59 in). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.
It resists engine and transmission fluids, aggressive chemicals, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is valued for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or ketones and esters.
You will find this material specified across aerospace, high-temperature process equipment, and oil and gas.
Stocked as V2.5X137 and sold individually. Unit weight is approximately 3.984 g. Check the compound against your process media, pressure and temperature before committing to a design.
