-353 BLACK FKM 75D O-RING

Part number V70353 is an AS568-353 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 4.975 in (126.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.395 in (137.03 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to petroleum oils and fuels, aromatic hydrocarbons, and aggressive chemicals. Viton® (FKM) is widely chosen for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to amines or hot water and steam will shorten service life.

Maintenance and OEM teams specify it across semiconductor equipment, automotive fuel systems, and high-temperature process equipment.

Stocked as V70353 and sold individually. Unit weight is approximately 16.913 g and nominal inside diameter is listed as 5 inch.
