-413 BROWN FKM 75D O-RING

The VB75413 is an AS568-413 brown Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 2.975 in (75.57 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.525 in (89.54 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. It resists aromatic hydrocarbons, aggressive chemicals, and chlorinated solvents. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or ketones and esters will shorten service life.

Typical settings include high-temperature process equipment, oil and gas, and aerospace.

VB75413 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
