What happens is it never gets tight and I can turn the hose even though it's screwed on as tight as it'll go. The threads seem to be the same as it screws on fine.
This is all low pressure stuff. If you don't want to fool with Camco, take the fittings to Depot or Lowes. Ask the pipefitter to help you match up proper thread, sounds like machine threads vs tapered pipe threads. Even if you have to use a short piece of vinyl with hose clamps you'll get up and running! Hope it works for you!
