3MM CS X 42MM ID BLACK FKM 75D

APG stocks the V3X42, a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 42 mm (1.654 in), a cross section of 3 mm (0.118 in), and an outside diameter of 48 mm (1.89 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. It resists aggressive chemicals, many acids, and petroleum oils and fuels. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It should not be specified for service in low-molecular-weight organic acids or amines.

You will find this material specified across oil and gas, chemical processing, and aerospace.
