V70161 is an AS568-161 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 5.487 in (139.37 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 5.693 in (144.6 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The material holds up against many acids, engine and transmission fluids, and aromatic hydrocarbons. Viton® (FKM) is widely chosen for long service life in hot, chemically aggressive environments and outstanding high-temperature capability. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to amines or low-molecular-weight organic acids will shorten service life.
Maintenance and OEM teams specify it across automotive fuel systems, chemical processing, and semiconductor equipment.
Order part number V70161, sold individually. Unit weight is approximately 4.396 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
