-211 BROWN FKM 75D O-RING

Part number VB75211 is an AS568-211 brown Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 0.796 in (20.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.074 in (27.28 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to aromatic hydrocarbons, aggressive chemicals, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where amines or low-molecular-weight organic acids are present.

Common environments for this compound include aerospace, chemical processing, and oil and gas.

Order part number VB75211, sold individually. Unit weight is approximately 1.5107 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
