Viton 75-247-Black-Pk5

SB-V70247-5 is an AS568-247 black Viton® (FKM) 70 Shore A O-Ring measuring an inside diameter of 4.609 in (117.07 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.887 in (124.13 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. The catalog record notes: 0.139CSX4.609"IDX4.887"OD.

The compound resists aromatic hydrocarbons, chlorinated solvents, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in amines or low-molecular-weight organic acids.

Typical settings include semiconductor equipment, chemical processing, and automotive fuel systems.

Reference part number SB-V70247-5 when ordering; the item is sold by the bag. Nominal inside diameter is listed as 4 5/8 inch. Check the compound against your process media, pressure and temperature before committing to a design.
