-426 BROWN FKM 90D O-RING

Part number VB90426 is an AS568-426 brown Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 4.6 in (116.84 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.15 in (130.81 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to many acids, engine and transmission fluids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) offers 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). It should not be specified for service in low-molecular-weight organic acids or ketones and esters.

Typical settings include automotive fuel systems, aerospace, and chemical processing.

Reference part number VB90426 when ordering; the item is sold individually. Unit weight is approximately 33.217 g and nominal inside diameter is listed as 4 5/8 inch. Check the compound against your process media, pressure and temperature before committing to a design.
