Hi,
I, Dick Werner, invented this trap seal set in 1975 while looking for a way to avoid purchasing an expensive part from the manufacturer. I also wrote the installation manual for my customers and copyrighted it in 2003. It helped thousands of people to dodge hefty repair bills. Pretty much 100% of offers from others are unattributed clones of my work.
Happy to share my over 50 years experience of working with Hasselblad. Sold over 55,000 sets of trap seals.
This auction is for one NEW Hasselblad film magazine Trap Seal (Light Seal) set - 1 FOIL + 1 FOAM and my copyrighted (2003 INSTALLATION INSTRUCTION- - will fit and work on all your Hasselblad film magazines.
THERE IS NO NEED TO REPLACE VELVET STRIP EVERY TIME WHEN YOU REPLACING TRAP SEAL!!!
If you have a light leak, you need to replace the trap seals on your film magazine, as this is the only place your magazine can leak light. If shooting professionally, you should do this at least once a year, as the trap seals do wear out, and it is a shame to develop your film and find that the entire shoot has to be done over due to fogging of the film. Most professionals change these trap seals about once a year to insure that they will not have fogged film on a shoot.
These seals are manufactured by me and I have used these seals on literally 1,000's of magazines with no problems. In fact, about half the repair technicians throughout the country are using my seals at this time. The seals are time tested. It will take you no more than 5/10 minutes to change seals. A small screw driver is the only tool required to change the seals on any film magazine.
The seal set comes with MY COPYRIGHTED instruction sheet as pictured below. This instruction sheet will answer all your questions on changing the seals.A HINT FOR CHECKING YOUR TRAP SEAL: Naturally, if you have random light streaks across your film, you have a light leak and bad seal set. Beyond this, you can check your trap seal in 2 ways. Remove your dark slide and hold the magazine up to a very bright light. Looking at the dark slide area from the opposite side of magazine (from the crank side), check to see if there is light coming through anywhere the dark slide would come through. If so, you have a bad trap seal. You can carry this a little further, by inserting the corner of your dark slide into the magazine and twisting very slightly on the dark slide. Again, if you see any light coming through, you have a leak. The leak will normally start at the upper edge of the seal, so especially look at this section of the seal.
