-339 BLACK FKM 75D O-RING

This o-ring is supplied in AS568-339 black Viton® (FKM) 75 Shore A measuring an inside diameter of 3.225 in (81.92 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.645 in (92.58 mm), catalogued under part number V75339. It delivers dependable bidirectional sealing in a compact groove envelope.

It resists many acids, petroleum oils and fuels, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is known for excellent resistance to compression set and permeation, outstanding high-temperature capability. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving hot water and steam or low-molecular-weight organic acids call for a different compound.

Typical settings include semiconductor equipment, aerospace, and chemical processing.

Stocked as V75339 and sold individually. Unit weight is approximately 11.3263 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
