4MM CS X 98MM ID BLACK FKM 75D

APG stocks the V4X98, a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 98 mm (3.858 in), a cross section of 4 mm (0.157 in), and an outside diameter of 106 mm (4.17 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists engine and transmission fluids, aggressive chemicals, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) delivers long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with ketones and esters or amines.

You will find this material specified across automotive fuel systems, aerospace, and chemical processing.

Order part number V4X98, sold individually. Unit weight is approximately 7.303 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
