4MM CS X 35MM ID BLACK FKM 75D

APG stocks the V4X35, a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 35 mm (1.378 in), a cross section of 4 mm (0.157 in), and an outside diameter of 43 mm (1.69 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Viton® (FKM) is specified here for very low compression set at elevated temperature and outstanding high-temperature capability. This material stands up to aggressive chemicals, aromatic hydrocarbons, and petroleum oils and fuels. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving ketones and esters or amines call for a different compound.

Common environments for this compound include aerospace, high-temperature process equipment, and automotive fuel systems.

V4X35 ships individually. Unit weight is approximately 2.8345 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
