Solon 20F30 Flange Washer, Imperial, 1-1/4 in, 1.281 in ID, 2.308 in OD, 0.309 in Thick, Tool Steel

Certain industries that utilize piping flange joint assemblies, such as petrochemical, dictate a low tolerance for fugitive emissions. Flange live loading, which is a process imperative to controlling gasket leaks in piping and refining operations, depends on the mission-critical performance. It is estimated that up to 92% of all flange leaks are caused by insufficient or loss of bolt preload. Solon brand Flange Washers are designed to maintain sufficient bolt tension and resultant gasket stresses in high temperature and high-pressure applications where safety and emission containment take priority. Solon brand Flange Washers are simply Belleville springs that are designed to be used in flange applications. The springs are engineered to fit into flange designs and the loads are typically higher than standard Belleville washers. Engineered to withstand extreme temperatures as well as corrosive environments. Contact us for an engineered solution to your custom specifications and unique application requirements. Made in USA.
