5MM CS X 120MM ID BLACK FKM 75D

This o-ring is supplied in black Viton® (FKM) 75 Shore A supplied with an inside diameter of 120 mm (4.724 in), a cross section of 5 mm (0.197 in), and an outside diameter of 130 mm (5.12 in), catalogued under part number V5X120. It creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to aggressive chemicals, many acids, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is known for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where ketones and esters or hot water and steam are present.

Maintenance and OEM teams specify it across automotive fuel systems, chemical processing, and oil and gas.

V5X120 ships individually. Unit weight is approximately 14.224 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
