-266 BLACK CHEMOURS VITON 75D O-RING

Ordered as VITON75266, this is an AS568-266 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 7.984 in (202.79 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 8.262 in (209.85 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to petroleum oils and fuels, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

Maintenance and OEM teams specify it across high-temperature process equipment, aerospace, and oil and gas.

Order part number VITON75266, sold individually. Unit weight is approximately 11.566 g and nominal inside diameter is listed as 8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
