-418 BLACK CHEMOURS VITON 75D O-RING

VITON75418 is an AS568-418 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 3.6 in (91.44 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.15 in (105.41 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against aromatic hydrocarbons, aggressive chemicals, and many acids. That behavior comes from the compound itself: Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in low-molecular-weight organic acids or hot water and steam.

Common environments for this compound include aerospace, automotive fuel systems, and chemical processing.

This item is sold individually under part number VITON75418. Unit weight is approximately 22.081 g and nominal inside diameter is listed as 3 5/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
