Ordered as VITON75219, this is an AS568-219 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 1.296 in (32.92 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.574 in (39.98 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Expect good resistance to engine and transmission fluids, aggressive chemicals, and many acids. Viton® (FKM) is known for outstanding high-temperature capability 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 ketones and esters or hot water and steam will shorten service life.
Maintenance and OEM teams specify it across semiconductor equipment, high-temperature process equipment, and oil and gas.
Order part number VITON75219, sold individually. Unit weight is approximately 2.0969 g and nominal inside diameter is listed as 1 5/16 inch. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
