2.5MM CS X 128MM ID BLACK FKM 75D

APG stocks the V2.5X128, a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 128 mm (5.039 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 133 mm (5.24 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Viton® (FKM) is specified here for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. The material holds up against engine and transmission fluids, aggressive chemicals, and petroleum oils and fuels. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or ketones and esters.

Maintenance and OEM teams specify it across semiconductor equipment, high-temperature process equipment, and aerospace.

V2.5X128 ships individually. Unit weight is approximately 3.6771 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
