-277 BLACK FKM 75D O-RING

This o-ring is supplied in AS568-277 black Viton® (FKM) 75 Shore A built to an inside diameter of 11.484 in (291.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 11.762 in (298.75 mm), catalogued under part number V70277. It compresses into its gland to block fluid or gas migration across a joint.

The compound resists aromatic hydrocarbons, many acids, and aggressive chemicals. Viton® (FKM) delivers 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). Exposure to amines or hot water and steam will shorten service life.

You will find this material specified across aerospace, oil and gas, and automotive fuel systems.

V70277 ships individually. Unit weight is approximately 16.63 g. Check the compound against your process media, pressure and temperature before committing to a design.
