-335 BROWN FKM 75D O-RING

This o-ring is supplied in AS568-335 brown Viton® (FKM) 75 Shore A measuring an inside diameter of 2.725 in (69.22 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.145 in (79.88 mm), catalogued under part number VB75335. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists chlorinated solvents, aromatic hydrocarbons, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is valued for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where low-molecular-weight organic acids or amines are present.

You will find this material specified across high-temperature process equipment, aerospace, and automotive fuel systems.

This item is sold individually under part number VB75335. Unit weight is approximately 10.68 g and nominal inside diameter is listed as 2 3/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
