Product Specification

-
VB90377 is an AS568-377 brown Viton® (FKM) 90 Shore A O-Ring measuring an inside diameter of 9.975 in (253.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.395 in (264.03 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to chlorinated solvents, many acids, and engine and transmission fluids. Viton® (FKM) offers long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

You will find this material specified across oil and gas, high-temperature process equipment, and semiconductor equipment.

Reference part number VB90377 when ordering; the item is sold individually. Nominal inside diameter is listed as 10 inch. Check the compound against your process media, pressure and temperature before committing to a design.
