-149 BLACK FKM 75D O-RING

The V75149 is an AS568-149 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 2.8 in (71.12 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.006 in (76.35 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Viton® (FKM) is known for long service life in hot, chemically aggressive environments and outstanding high-temperature capability. This material stands up to engine and transmission fluids, many acids, and aggressive chemicals. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or hot water and steam will shorten service life.

Maintenance and OEM teams specify it across chemical processing, oil and gas, and aerospace.

This item is sold individually under part number V75149. Nominal inside diameter is listed as 2 13/16 inch. Check the compound against your process media, pressure and temperature before committing to a design.
