4MM CS X 165MM ID BLACK FKM 75D

Part number V4X165 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 165 mm (6.496 in), a cross section of 4 mm (0.157 in), and an outside diameter of 173 mm (6.81 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Expect good resistance to engine and transmission fluids, aromatic hydrocarbons, and aggressive chemicals. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It is not the right choice where hot water and steam or amines are present.

Typical settings include aerospace, semiconductor equipment, and high-temperature process equipment.

Order part number V4X165, sold individually. Unit weight is approximately 12.196 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
