OmniLip™ and DynaLip® Seals

Metal-Cased Rotary Lip Seals

OmniLip™ was introduced in the early 1970’s and DynaLip® was created in the late 1980’s. The seals were designed to bridge the gap between conventional elastomer lip seals and mechanical face seals. The ability to perform in hostile environments such as extreme temperatures, aggressive media, high surface speeds, high pressure and lack of lubrication are important features of Saint-Gobain Seals Group’s PTFE rotary lip seals. They provide the designer with a significant improvement in performance over elastomer lip seals while delivering value-added benefits. Both rotary lip seals are used in a variety of applications in different industries.
