4MM CS X 170MM ID BLACK FKM 75D

Ordered as V4X170, this is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 170 mm (6.693 in), a cross section of 4 mm (0.157 in), and an outside diameter of 178 mm (7.01 in). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists aromatic hydrocarbons, petroleum oils and fuels, and engine and transmission fluids. Viton® (FKM) is valued for long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving low-molecular-weight organic acids or hot water and steam call for a different compound.

Maintenance and OEM teams specify it across chemical processing, semiconductor equipment, and automotive fuel systems.

This item is sold individually under part number V4X170. Unit weight is approximately 12.415 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
