**4 MM C/S X 25 MM ID (GREEN)

The VG4X25 is a green Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 25 mm (0.984 in), a cross section of 4 mm (0.157 in), and an outside diameter of 33 mm (1.3 in). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. Source specification: 75 Duro Fluoroelastomer Metric O-RING.

As a material, Viton® (FKM) offers excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. The material holds up against aggressive chemicals, many acids, and aromatic hydrocarbons. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in amines or ketones and esters.

Typical settings include automotive fuel systems, high-temperature process equipment, and semiconductor equipment.
