-358 BLACK FKM 75D O-RING

V75358 is an AS568-358 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 5.6 in (142.24 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.02 in (152.91 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to many acids, aromatic hydrocarbons, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is specified for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or low-molecular-weight organic acids will shorten service life.

Maintenance and OEM teams specify it across aerospace, oil and gas, and high-temperature process equipment.

Order part number V75358, sold individually. Nominal inside diameter is listed as 5 5/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
