4MM CS X 365MM ID BLACK FKM 75D

Ordered as V4X365, this is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 365 mm (14.37 in), a cross section of 4 mm (0.157 in), and an outside diameter of 373 mm (14.69 in). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Viton® (FKM) is specified here for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. This material stands up to aggressive chemicals, engine and transmission fluids, and aromatic hydrocarbons. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or ketones and esters will shorten service life.

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

Reference part number V4X365 when ordering; the item is sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
