-338 BLUE FKM 75D O-RING

Part number V75MD338 is an AS568-338 blue Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 3.1 in (78.74 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.52 in (89.41 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to aromatic hydrocarbons, petroleum oils and fuels, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) offers very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or ketones and esters will shorten service life.

This item meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include chemical processing, high-temperature process equipment, and automotive fuel systems.

Reference part number V75MD338 when ordering; the item is sold individually. 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.
