4MM CS X 410MM ID BLACK FKM 75D

This o-ring is supplied in black Viton® (FKM) 75 Shore A supplied with an inside diameter of 410 mm (16.142 in), a cross section of 4 mm (0.157 in), and an outside diameter of 418 mm (16.46 in), catalogued under part number V4X410. It remains the most cost-effective sealing element available for pressurized assemblies.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. The compound resists petroleum oils and fuels, many acids, and aromatic hydrocarbons. 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 amines or low-molecular-weight organic acids are present.

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

This item is sold individually under part number V4X410. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
