Ordered as V2.5X75, this is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 75 mm (2.953 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 80 mm (3.15 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.
Expect good resistance to engine and transmission fluids, aggressive chemicals, and many acids. That behavior comes from the compound itself: Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with hot water and steam or low-molecular-weight organic acids.
It sees regular use in high-temperature process equipment, automotive fuel systems, and aerospace.
This item is sold individually under part number V2.5X75. Unit weight is approximately 2.2457 g. Review your operating media and conditions against this specification before installation.
