Superglue the couplers to the piping and then use clamps. It sounds stupid but it works. Trust me!

When I had my eclipse and was running 25-26psi, my couplers would pop off all the time until someone told me to use the superglue. I never had a problem with them again.

If you need to remove the couplers, you just take a flathead screwdrive and ring the inside of the coupler and they come off fairly easy.
