-366 BROWN FKM 75D O-RING

Ordered as VB75366, this is an AS568-366 brown Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 7.225 in (183.52 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.645 in (194.18 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to aggressive chemicals, many acids, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) delivers 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). Exposure to low-molecular-weight organic acids or ketones and esters will shorten service life.

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

Order part number VB75366, sold individually. Unit weight is approximately 27.235 g and nominal inside diameter is listed as 7 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
