.210" C/S (3/16" NOMINAL) (5.33 MM)

The 0283210 is a black Viton® (FKM) 75 Shore A O-Ring Cord Stock built to a cross section of 0.21 in (5.33 mm). This o-ring cord stock provides continuous extruded stock for building one-off or oversized rings.

The compound resists petroleum oils and fuels, aggressive chemicals, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) delivers outstanding high-temperature capability, excellent resistance to compression set and permeation. Exposure to hot water and steam or ketones and esters will shorten service life.

Maintenance and OEM teams specify it across oil and gas, aerospace, and chemical processing.

This item is sold by the foot under part number 0283210. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
