5MM CS X 21MM ID BLACK FKM 75D

V5X21 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 21 mm (0.827 in), a cross section of 5 mm (0.197 in), and an outside diameter of 31 mm (1.22 in). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists many acids, aggressive chemicals, and chlorinated solvents. 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. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service.

Typical settings include oil and gas, aerospace, and chemical processing.
