-344 BLACK FKM 90D O-RING

Part number V90344 is an AS568-344 black Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 3.85 in (97.79 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.27 in (108.46 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists aromatic hydrocarbons, aggressive chemicals, and many acids. That behavior comes from the compound itself: Viton® (FKM) is valued for excellent resistance to compression set and permeation, outstanding high-temperature capability. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving hot water and steam or low-molecular-weight organic acids call for a different compound.

Common environments for this compound include high-temperature process equipment, aerospace, and semiconductor equipment.

V90344 ships individually. Unit weight is approximately 13.368 g and nominal inside diameter is listed as 3 7/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
