Type T21 MET Seals are part of a family of Diaphragm Rubber bellow Seals and are interchangeable with many other makes including John Crane Types 1A & 2 as well as Sealol 043 CE Long and Short.     The Bellow rotates with the shaft and can accommodate some end float, eccentricity and missalignment.

Benefits             

Positive drive      Reduces Bellow Stress  

Self adjusting      Bellow takes care of wear and                                  shaft float       

Long life              Due to minimum face loading       Non clogging     Due to open single spring design Non fretting        No moving O-rings       

Bi-directional      Due to positive drive

    

All metal parts in Stainless Steel as standard
