**4MM C/S X 30 MMID (GREEN)

This o-ring is supplied in green Viton® (FKM) 75 Shore A supplied with an inside diameter of 30 mm (1.181 in), a cross section of 4 mm (0.157 in), and an outside diameter of 38 mm (1.5 in), catalogued under part number VG4X30. It compresses into its gland to block fluid or gas migration across a joint. The catalog record notes: 75 Duro Fluoroelastomer Metric O-RING.

Expect good resistance to engine and transmission fluids, chlorinated solvents, and aggressive chemicals. Viton® (FKM) is known for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving low-molecular-weight organic acids or amines call for a different compound.

Maintenance and OEM teams specify it across chemical processing, semiconductor equipment, and aerospace.

Stocked as VG4X30 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
