5MM CS X 155MM ID BLACK FKM 75D

APG stocks the V5X155, a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 155 mm (6.102 in), a cross section of 5 mm (0.197 in), and an outside diameter of 165 mm (6.5 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to aggressive chemicals, many acids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is specified for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where hot water and steam or amines are present.

Maintenance and OEM teams specify it across chemical processing, automotive fuel systems, and oil and gas.

Reference part number V5X155 when ordering; the item is sold individually. Unit weight is approximately 18.032 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
