Mamiya RB Film Back Seals

$11.50
This USCamera custom seal kit set will service all RB 67  RB 67 Pro/Pro S 120, 220, and 645 film backs.  The RB film back consists of the shell and insert. In checking these film backs for years, if the shell seals are bad so are the insert seals, therefore I recommend replacing them as a set.   The 6 piece insert kit includes channel seals for the front of the top and bottom covers, top/bottom seals left guide roller plate and top/bottom seals right guide roller plate.  The 4 piece shell kit includes 2 door channel seals on the back cover, 1 back cover hinge seal and 1 back cover door latch seal. Also, check the revolving adapter. When the film back seals are sticky, the revolving adapters foam is usually sticky also. Mamiya made different adapter plates for the  RB Pro and the RB Pro S/Pro SD. Links to the placement guides will show you what you need to know about them. We have received many orders for the seals either for shell or insert only. I contacted many of those customers and most didn't realize they needed to check the other half of the set. That being said, if you are absolutely positive you want to purchase them separately, go here shell or insert. USCamera RB 67 film back placement guide will help with installing these kits.
