Ordered as V75465, this is an AS568-465 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 17.955 in (456.06 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 18.505 in (470.03 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
The compound resists aggressive chemicals, petroleum oils and fuels, and many acids. That behavior comes from the compound itself: Viton® (FKM) is known for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or amines.
Typical settings include aerospace, semiconductor equipment, and high-temperature process equipment.
