-350 BROWN FKM 75D O-RING

The VB75350 is an AS568-350 brown Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 4.6 in (116.84 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.02 in (127.51 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists petroleum oils and fuels, chlorinated solvents, and many acids. Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to amines or ketones and esters will shorten service life.

Maintenance and OEM teams specify it across automotive fuel systems, aerospace, and high-temperature process equipment.

This item is sold individually under part number VB75350. Unit weight is approximately 17.506 g and nominal inside diameter is listed as 4 5/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
