This o-ring is supplied in black Viton® (FKM) 75 Shore A with an inside diameter of 175 mm (6.89 in), a cross section of 4 mm (0.157 in), and an outside diameter of 183 mm (7.2 in), catalogued under part number V4X175. It creates a positive seal at flange, piston and rod interfaces without added hardware.
This material stands up to aromatic hydrocarbons, engine and transmission fluids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with hot water and steam or ketones and esters.
Common environments for this compound include semiconductor equipment, automotive fuel systems, and aerospace.
V4X175 ships individually. Unit weight is approximately 12.669 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
