2MM CS X 79MM ID BLACK FKM 75D

Ordered as V2X79, this is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 79 mm (3.11 in), a cross section of 2 mm (0.079 in), and an outside diameter of 83 mm (3.27 in). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to chlorinated solvents, aromatic hydrocarbons, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is known for long service life in hot, chemically aggressive environments and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving hot water and steam or low-molecular-weight organic acids call for a different compound.

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

Order part number V2X79, sold individually. Unit weight is approximately 1.4913 g. 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.
