Viton 75-429-Black-Pk2

The SB-V70429-2 is an AS568-429 black Viton® (FKM) 70 Shore A O-Ring supplied with an inside diameter of 4.975 in (126.37 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.525 in (140.34 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies. Supplementary detail from the product record: 0.275CSX4.975"IDX5.525"OD.

Expect good resistance to many acids, aromatic hydrocarbons, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is valued for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or ketones and esters.

Maintenance and OEM teams specify it across chemical processing, semiconductor equipment, and high-temperature process equipment.

SB-V70429-2 ships by the bag. Nominal inside diameter is listed as 5 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
