Well damnnnn. Too good to be true. So the inside diameter from the websites state 1.56 to 1.6 which worked fine for a 1.5” plastic barbed fitting but was too big for a smooth walled bronze 1.5” OD drains that I am using. The marine supply stuff is a true 1.5 or close to it. I had to go with the $8 a foot stuff. I felt to clamp it down that much might put undue pressure on the hose and create a weak spot. Don’t know for sure but it didn’t feel right to me. So it could work just depends on what you are connecting it to. I’m going all bronze.
