PTFE sealing lips are PTFE compound discs that are mechanically formed to a diameter slightly smaller than the shaft. The forming of the lip creats a shape that takes advantage of the hoop strength of the PTFE compound discs. This hoop strength provides the load that is critical for low or no pressure applications to obtain a positive seal.The sealing element typically has a smooth surface contacting the shaft.

SUMIFLON MUSHSEAL is a registered trade mark of Sumitomo Electric. It is produced by patented method, JAP PAT NO. 516838. MUSHSEAL is a versatile gasket makde of pure PTFE. It is soft, plain and conformable even to irregular surface. The self-adhesive film on MUSHSEAL makes sealing work easy even on vertical or overhead surfaces. MUSHSEAL is economical, cut off only the desired length from the spool. Sealing effect is excellent and semi-permanent. For applications sealing liquid at below 0.1Mpa, a hydrodynamic spiral feature can be machined into the surface of the sealing element to provide a positive pumping action to drive fluid away from the air side of the seal.It is critical to match the seal to the shaft rotation to ensure positive sealing. Sealing element Material Selection:LP1001 Premium grade virgin PTFE for static, slow-dynamic or light-duty application.
