3.1MM CS X 34.4MM ID BLACK FKM 75D

APG stocks the V3.1X34.4, a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 34.4 mm (1.354 in), a cross section of 3.1 mm (0.122 in), and an outside diameter of 40.6 mm (1.6 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope. Source specification: Metric O-RING, JIS G35.

The material holds up against aromatic hydrocarbons, aggressive chemicals, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) delivers long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or amines will shorten service life.

It sees regular use in aerospace, high-temperature process equipment, and chemical processing.

V3.1X34.4 ships individually. Unit weight is approximately 1.6446 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
