Mechanical seals are critical components that prevent fluid leakage between a rotating shaft and stationary housing in pumps, compressors, mixers, and agitators. By creating a secure seal at the shaft interface, they ensure equipment reliability, efficiency, and compliance with environmental and safety regulations.
Flexaseal designs and manufactures high-performance mechanical seals in the U.S., engineered for the most demanding applications. From chemical processing and oil & gas to water treatment, power generation, and pharmaceuticals, our seals deliver exceptional performance, longer service life, and reduced downtime.
