-407 BLACK CHEMOURS VITON 75D O-RING

APG stocks the VITON75407, an AS568-407 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 2.225 in (56.52 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 2.775 in (70.49 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists aromatic hydrocarbons, many acids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is valued for outstanding high-temperature capability and very low compression set at elevated temperature. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or amines are present.

It sees regular use in semiconductor equipment, oil and gas, and aerospace.

VITON75407 ships individually. Unit weight is approximately 13.938 g. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
