V3.1X134.4 is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 134.4 mm (5.291 in), a cross section of 3.1 mm (0.122 in), and an outside diameter of 140.6 mm (5.54 in). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. Source specification: Metric O-RING, JIS G135.

Viton® (FKM) is specified here for very low compression set at elevated temperature, excellent resistance to compression set and permeation. Expect good resistance to petroleum oils and fuels, many acids, and engine and transmission fluids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where low-molecular-weight organic acids or amines are present.

Maintenance and OEM teams specify it across aerospace, automotive fuel systems, and oil and gas.
