-404 BLACK CHEMOURS VITON 75D O-RING

Part number VITON75404 is an AS568-404 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 1.85 in (46.99 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 2.4 in (60.96 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Expect good resistance to many acids, chlorinated solvents, and petroleum oils and fuels. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where ketones and esters or hot water and steam are present.

Maintenance and OEM teams specify it across semiconductor equipment, automotive fuel systems, and high-temperature process equipment.

VITON75404 ships individually. Unit weight is approximately 12.014 g and nominal inside diameter is listed as 1 7/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
