Mamiya RB Back Shell Seals

This USCamera custom seal kit will service all RB 67  RB 67 Pro / Pro S 120, 220, and 645 film back shells only. This 1/2 of what I recommend you replace. The other 1/2 is the insert kit

The RB film back consists of the shell and insert. In checking film backs for years, if the shell seals are bad so are the insert seals, so I recommend replacing them as a set. You may purchase the complete film back kit here

This is the shell kit only and includes 2 door channel seals on the back cover, 1 back cover hinge seal and 1 back cover door latch seal.


USCamera RB 67 film back placement guide will help with installing the shell kits. Look here

First of all, the most important work you have to do is to remove the old seals. Focus on clean, clean, clean. Also, carefully clean the old residue from the door channels, mirror cushion area, door hinge area and anywhere else you are replacing the seals. Furthermore, the finest adhesive in the world will not adhere to that sticky, gooey residue that was once a quality light seal. Finally, proper installation will give you thousands of light tight exposures.

Film cameras may be in the past, for now, however, Mamiya Leaf is still going strong. Look here.
