Also known as lip seals, these are ideal seals for rotating equipment. They seal these rotating parts such as rotating bores, strut seals, hydraulic pumps, and so on.

The lip seal is elastomeric performs the actual sealing function. The garter spring offers the required flexibility of movement and quite complements the lip seal. This is a basic design which can be customized to suit specific requirements. These seals are extremely versatile can be made of a variety of materials ranging from hard metals to plastic. The most common materials are steel, brass, silicone rubber, and EPDM. There are many processes or applications where a certain level of pressure and temperature needs to be maintained.
