.437" C/S (7/16") (11.10 MM)

0283437 is a black Viton® (FKM) 75 Shore A O-Ring Cord Stock built to a cross section of 0.437 in (11.1 mm). In service, this o-ring cord stock lets you fabricate a custom-size seal on site by cutting and splicing to the required circumference.

Expect good resistance to aromatic hydrocarbons, aggressive chemicals, and chlorinated solvents. Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Applications involving ketones and esters or hot water and steam call for a different compound.

Maintenance and OEM teams specify it across semiconductor equipment, automotive fuel systems, and aerospace.
