-432 BROWN FKM 90D O-RING

VB90432 is an AS568-432 brown Viton® (FKM) 90 Shore A O-Ring supplied with an inside diameter of 5.35 in (135.89 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.9 in (149.86 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. This material stands up to many acids, aromatic hydrocarbons, and chlorinated solvents. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It should not be specified for service in hot water and steam or low-molecular-weight organic acids.

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

VB90432 ships individually. Unit weight is approximately 38.2395 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
