.375" C/S (3/8") (9.53 MM)

APG stocks the 0283VB375, a brown Viton® (FKM) 75 Shore A O-Ring Cord Stock supplied with a cross section of 0.375 in (9.53 mm). An o-ring cord stock provides continuous extruded stock for building one-off or oversized rings. Source specification: 75 Duro Brown Fluoroelastomer ORING Cord.

The compound resists chlorinated solvents, aggressive chemicals, and many acids. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. It should not be specified for service in low-molecular-weight organic acids or ketones and esters.

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

Order part number 0283VB375, sold by the foot. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
