  1. I had the same problem...mine was getting the bulkhead O ring to seat properly due to interference with the housing casting. Is there any interference on your housing?. I used a bicycle torque wrench and snugged mine down to 5 Nm, if that helps. It did cut the threads into the paint on the side of the casting. Of course, it may be that you have another leak elsewhere, but the most likely explanation is the new fitting. Also make sure there is no air leaking around the pump to gauge interface. I used a cork to replace the pump handle while assessing stability of the vacuum. ian
  2. I spoke with Scott at Backscatter. He assured me that all the black fittings are anodized aluminum I have confirmed this by removing my bulkhead and found that where the threads interfere with the casting on my Subal ND3, the threads are now silver. Backscatter has a solution to this interference problem on my housing and will be producing bulkhead fittings that are slightly taller before the threaded portion begins. That will clear the lip on the casting that binds the thread as the bulkhead seats. It will also allow the threaded cap or Airlock fitting to seat completely in the bulkhead which it doesn't currently do on my housing. That should definitively solve this issue on my housing. Ian
  3. I received my Airlock last night and installed it on my Subal ND3. I sent the following feedback email to Sean at backscatter this morning: Sean Some feedback on myAir Lock install last night. Housing is a Subal ND3. Installed the bulkhead fitting with a bit of lube on the o ring. I did not use threadlock. Originally used a crescent wrench. Is the bulkhead fitting made of metal or plastic? The outer threaded part of the fitting was a fraction too wide for the surrounding lip of the housing casting. There was some interference once the fitting threaded in far enough and would not seat the o ring on the mating surface of the housing. My first try yielded a slow leak that would go from -10 to zero in about ten minutes. I disassembled everything, cleaned and regreased and on the second try used an 11/16 socket. The fitting actually cut some threads into the paint of the housing. I got to the original install depth and then gave an extra 1/4 turn until it completely stopped. I reassembled and pulled -10 which held perfectly overnight. This interference may be a one off due to the position of the bulkhead hole relative to the surrounding casting, but knowing Subal, I doubt it. Had I dived the housing it would have leaked. It is important to stress that ANY loss of vacuum indicates a leak. At -10 in/Hg my ports would still rotate but could not be removed. The other point I would make is that when testing the stability of the vacuum, I used a synthetic cork from a wine bottle to plug the hole in the gauge where the pump handle would go, rather than the pump. It is easier to handle and eliminates the possiblity of air leaking from the pump side. You could even throw a cork in with the packaging. FYI my math indicates that -10 in/Hg is equal to 11 FSW or 10 feet of fresh water. The other use of this product is to tell you when your housing needs a rebuild. Apart from the interference problem, everything is perfect. You just need to know it is a potential glitch, and hopefully the paint won't chip off. Great product, no doubt! ian
  4. Sorry I wasn't clear. I want the option of using a D3X and a D3s in the same housing without loss of functionality of either... ian
  5. May have been asked before but I can't find it! Has anyone experience with using a Nikon D3/D3X in a D3S Subal housing. Is there a downside, button placement issues etc. I realize there is no Live View button or Info button on the D3/D3X, but do all the other buttons line up? I am thinking in terms of camera upgrade for video. Ian
