-445 BROWN FKM 75D O-RING

APG stocks the VB75445, an AS568-445 brown Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 7.975 in (202.57 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 8.525 in (216.54 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists many acids, chlorinated solvents, and aromatic hydrocarbons. Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or hot water and steam are present.

Common environments for this compound include aerospace, high-temperature process equipment, and semiconductor equipment.
