-329 BROWN FKM 75D O-RING

The VB75329 is an AS568-329 brown Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 1.975 in (50.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.395 in (60.83 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists many acids, petroleum oils and fuels, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving ketones and esters or low-molecular-weight organic acids call for a different compound.

Common environments for this compound include chemical processing, semiconductor equipment, and automotive fuel systems.

Order part number VB75329, sold individually. Unit weight is approximately 8.34 g and nominal inside diameter is listed as 2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
