Ordered as V75452, this is an AS568-452 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 11.475 in (291.47 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 12.025 in (305.44 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
The compound resists engine and transmission fluids, petroleum oils and fuels, and many acids. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in hot water and steam or low-molecular-weight organic acids.
Typical settings include automotive fuel systems, oil and gas, and semiconductor equipment.
This item is sold individually under part number V75452. Nominal inside diameter is listed as 11 1/2 inch. Review your operating media and conditions against this specification before installation.
