Product Detail
PTC uses both flexible and rigid elements that maintain contact at a sealing interface and slide on each other. This allows a rotating element to pass through a sealed case. The elements are both mechanically and hydraulically loaded with a spring or other device to maintain contact.
Internal face seals are used for static, slow-rotating or oscillating equipment such as low temperature flange seals or cap applications. High seal loads and face seals are ideal for gas and vacuum applications. Depending on the application, there are a variety of sealed jack materials and power types.
