-109 BLACK FKM 75D O-RING

APG stocks the V75109, an AS568-109 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 0.299 in (7.59 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.505 in (12.83 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Viton® (FKM) is known for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. This material stands up to many acids, aggressive chemicals, and chlorinated solvents. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

Common environments for this compound include automotive fuel systems, semiconductor equipment, and aerospace.

V75109 ships individually. Unit weight is approximately 0.3203 g and nominal inside diameter is listed as 5/16 inch. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
