.139" C/S (1/8" NOMINAL) (3.53 MM)

Ordered as 0283H139, this is a black Viton® (FKM) 90 Shore A O-Ring Cord Stock built to a cross section of 0.139 in (3.53 mm). The o-ring cord stock lets you fabricate a custom-size seal on site by cutting and splicing to the required circumference.

As a material, Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. The compound resists chlorinated solvents, many acids, and aromatic hydrocarbons. Exposure to amines or low-molecular-weight organic acids will shorten service life.

You will find this material specified across oil and gas, automotive fuel systems, and semiconductor equipment.

0283H139 ships by the foot. Check the compound against your process media, pressure and temperature before committing to a design.
