V75MD212 is an AS568-212 blue Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 0.859 in (21.82 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.137 in (28.88 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
As a material, Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. It resists many acids, aggressive chemicals, and aromatic hydrocarbons. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with hot water and steam or low-molecular-weight organic acids.
The compound meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. You will find this material specified across aerospace, semiconductor equipment, and high-temperature process equipment.
Order part number V75MD212, sold individually. Nominal inside diameter is listed as 7/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
