-418 BROWN FKM 75D O-RING

This o-ring is supplied in AS568-418 brown Viton® (FKM) 75 Shore A measuring an inside diameter of 3.6 in (91.44 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.15 in (105.41 mm), catalogued under part number VB75418. It compresses into its gland to block fluid or gas migration across a joint.

The material holds up against aggressive chemicals, many acids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is specified for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

Typical settings include chemical processing, high-temperature process equipment, and automotive fuel systems.

This item is sold individually under part number VB75418. Review your operating media and conditions against this specification before installation.
