-154 BROWN FKM 75D O-RING

This o-ring is supplied in AS568-154 brown Viton® (FKM) 75 Shore A with an inside diameter of 3.737 in (94.92 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.943 in (100.15 mm), catalogued under part number VB75154. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists engine and transmission fluids, petroleum oils and fuels, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) offers outstanding high-temperature capability and long service life in hot, chemically aggressive environments. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It should not be specified for service in amines or low-molecular-weight organic acids.

Typical settings include automotive fuel systems, aerospace, and semiconductor equipment.
