Sorry, you are using tape wrong. I know you are selling adapters, and they look great and I am sure fit great. But for those that already have an adapter, don't tape it AFTER you connect, tape BEFORE. The simple answer to most of these misfitting hose to coupler is just build up about 1/4" of blue painters tape on the male end of any duct adapter, now slide the hose over the tape and, poof, perfect fit. In many case, don't worry about the clamps, just put enough blue tape on the adapter to it fits super snug. All this talk about gaping is taken care of.
Heard a lot about hose, what about the boats?
