The V3.5X11 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 11 mm (0.433 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 18 mm (0.71 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.
Expect good resistance to aggressive chemicals, many acids, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) delivers excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. 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.
Typical settings include high-temperature process equipment, aerospace, and automotive fuel systems.
Order part number V3.5X11, sold individually. Unit weight is approximately 0.8028 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
