PTUF spring energized PTFE seal, Flanged profiles are clamped axially in the gland to ensure that the seal does not spin with the shaft, especially in applications with frequent thermal cycling.
Flanged seals are a special class of radial seals with an added feature to help retain the seal under rotary forces. The flange is an extension of the heel of the seal, which locates in a counterbore of the housing. At the assembly, the seal flange gets pinched in the housing providing a positive mechanical lock that keeps the seal stationary. Flanged seals are an excellent choice for equipment that can be designed with endplates. In these cases, assembly of a flanged seal is simple and provides a robust design as well as a level of redundant sealing on the static side of the gland. Process machinery that requires a product to be contained (mixers, augers, spool valves) are good applications of this design.
