Product Specification

-
The VB90311 is an AS568-311 brown Viton® (FKM) 90 Shore A O-Ring with an inside diameter of 0.537 in (13.64 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 0.957 in (24.31 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Viton® (FKM) is known for very low compression set at elevated temperature, excellent resistance to compression set and permeation. Expect good resistance to chlorinated solvents, engine and transmission fluids, and aggressive chemicals. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

Typical settings include semiconductor equipment, automotive fuel systems, and aerospace.

This item is sold individually under part number VB90311. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
