The pictures below shows the rod and seals, and the hydraulic jack manufacturer label for the Anson landing gear. We are in the process of replacing these seals. It should be noted that the only original seal made of O-ring rubber material is the rod seal. The original top, bottom and inner seals are made of some form of nylon or hard rubber. So far rubber O-ring type of material has been sourced for the upper seal, rod seal, and bottom seal. The inner seals which fits inside the threaded brass coupling and steal upper collar has not been sourced at this time.
Anyone that knows where the inner seals can be sourced please let us known. Thanks
