APG stocks the V3.5X18, a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 18 mm (0.709 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 25 mm (0.98 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.
As a material, Viton® (FKM) offers outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. It resists aromatic hydrocarbons, aggressive chemicals, and petroleum oils and fuels. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or amines will shorten service life.
Common environments for this compound include semiconductor equipment, oil and gas, and automotive fuel systems.
V3.5X18 ships individually. Unit weight is approximately 1.2048 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
