Omniseal® Rotary Lip Seals
Rotary Shaft Seals with Polymer Lips
About This Solution

Omniseal® polymer rotary lip seals were introduced in the early 1970s designed to bridge the gap between conventional elastomer lip seals and mechanical face seals. Also known as rotary shaft seals and made with a metal casing, the seal can be manufactured from a variety of materials for PTFE and PTFE-blended sealing elements. They perform well in hostile environments with extreme temperatures, aggressive media, high surface speeds, high pressure or lack of lubrication. These rotary lip seals along with spring-energized seals make an important impact in everyday life, protecting aviation jet engines, helicopter rotorheads and life science oxygen concentrators.

Materials

Using our expertise in PTFE and PTFE compounds, we have developed over 500 proprietary formulations in house that are used to meet the demands in a number of critical applications. These materials are compounded and processed to be optimized for tribological (friction and wear), mechanical and thermal properties.

Springs

Lip seals may have garter springs to help assist with the higher than acceptable runout/misalignment of the shaft and improve sealing under high speed. The springs may also add a consistent load combined with PTFE compounds.
