Viton 75-042-Black-Pk10

Part number SB-V70042-10 is an AS568-042 black Viton® (FKM) 70 Shore A O-Ring supplied with an inside diameter of 3.239 in (82.27 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.379 in (85.83 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. The catalog record notes: 0.070CSX3.239"IDX3.379"OD.

The material holds up against many acids, aromatic hydrocarbons, and aggressive chemicals. 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. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with ketones and esters or amines.

Maintenance and OEM teams specify it across semiconductor equipment, high-temperature process equipment, and automotive fuel systems.

Reference part number SB-V70042-10 when ordering; the item is sold by the bag. Nominal inside diameter is listed as 3 1/4 inch. Check the compound against your process media, pressure and temperature before committing to a design.
