-207 BROWN FKM 75D O-RING

APG stocks the VB75207, an AS568-207 brown Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 0.546 in (13.87 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.824 in (20.93 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against aromatic hydrocarbons, chlorinated solvents, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is known 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. Verify compatibility before use with low-molecular-weight organic acids or hot water and steam.

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

Reference part number VB75207 when ordering; the item is sold individually. Unit weight is approximately 1.0836 g and nominal inside diameter is listed as 9/16 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
