Viton 75-026-Black-Pk50

Part number SB-V70026-50 is an AS568-026 black Viton® (FKM) 70 Shore A O-Ring measuring an inside diameter of 1.239 in (31.47 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.379 in (35.03 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. Source specification: 0.070CSX1.239"IDX1.379"OD.

It resists many acids, aromatic hydrocarbons, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is known for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where hot water and steam or ketones and esters are present.

Maintenance and OEM teams specify it across chemical processing, automotive fuel systems, and semiconductor equipment.
