-429 BLACK FKM 75D O-RING

APG stocks the V70429, an AS568-429 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 4.975 in (126.37 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.525 in (140.34 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Viton® (FKM) delivers very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. This material stands up to many acids, petroleum oils and fuels, and engine and transmission fluids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving hot water and steam or low-molecular-weight organic acids call for a different compound.

You will find this material specified across semiconductor equipment, high-temperature process equipment, and chemical processing.

Order part number V70429, sold individually. Unit weight is approximately 29.379 g and nominal inside diameter is listed as 5 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
