This o-ring cord stock is supplied in black Viton® (FKM) 90 Shore A measuring a cross section of 0.187 in (4.75 mm), catalogued under part number 0283H187. It eliminates long lead times on large-diameter custom rings.

This material stands up to chlorinated solvents, engine and transmission fluids, and petroleum oils and fuels. Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation.

Maintenance and OEM teams specify it across high-temperature process equipment, oil and gas, and semiconductor equipment.
