-123 BLACK CHEMOURS VITON 75D O-RING

Part number VITON75123 is an AS568-123 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 1.174 in (29.82 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.38 in (35.05 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists aggressive chemicals, engine and transmission fluids, and many acids. That behavior comes from the compound itself: Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in amines or low-molecular-weight organic acids.

Maintenance and OEM teams specify it across aerospace, high-temperature process equipment, and chemical processing.
