-340 BLACK FKM 75D O-RING

APG stocks the V75340, an AS568-340 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 3.35 in (85.09 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.77 in (95.76 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Viton® (FKM) is specified here for outstanding high-temperature capability and very low compression set at elevated temperature. It resists many acids, aromatic hydrocarbons, and chlorinated solvents. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or amines will shorten service life.

It sees regular use in high-temperature process equipment, automotive fuel systems, and oil and gas.

V75340 ships individually. Unit weight is approximately 11.692 g and nominal inside diameter is listed as 3 3/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
