-441 BROWN FKM 75D O-RING

The VB75441 is an AS568-441 brown Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 6.975 in (177.17 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 7.525 in (191.14 mm). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to engine and transmission fluids, aggressive chemicals, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or low-molecular-weight organic acids will shorten service life.

Maintenance and OEM teams specify it across semiconductor equipment, high-temperature process equipment, and chemical processing.

VB75441 ships individually. Unit weight is approximately 45.245 g. Check the compound against your process media, pressure and temperature before committing to a design.
