I was very happy to find that Dr. Miller had sent me a new USN marked mouthpiece for my Voit Navy. It appears to be the same overall shape as the original Voit marked gray version. Upon installation, I found that the hose sections are of a thicker material. They hold the valve cages well, but being of thicker material, the hose clamps need to be around 0.25" longer than normal ones. I have tried original Voit ones, along with Bryan's reproductions. They worked, but needed longer screws to hold the nut securely. The protusion that normally fits under the opposite side barely touches the adjoining material. I am hoping that Bryan's provider also makes them in a longer size. Bryan's versions appear to be the same that Dive Rite uses on some of their products.
Any help, as usual, is much appreciated.
