2MM CS X 55MM ID BLACK FKM 75D

APG stocks the V2X55, a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 55 mm (2.165 in), a cross section of 2 mm (0.079 in), and an outside diameter of 59 mm (2.32 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against aggressive chemicals, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with ketones and esters or amines.

You will find this material specified across chemical processing, oil and gas, and aerospace.

Order part number V2X55, sold individually. Unit weight is approximately 1.044 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
