-254 BLACK FKM 75D O-RING

APG stocks the V70254, an AS568-254 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 5.484 in (139.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.762 in (146.35 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists many acids, petroleum oils and fuels, and engine and transmission fluids. 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. Exposure to amines or low-molecular-weight organic acids will shorten service life.

Common environments for this compound include chemical processing, oil and gas, and semiconductor equipment.

Stocked as V70254 and sold individually. Unit weight is approximately 8.0821 g and nominal inside diameter is listed as 5 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
