I absolutely hate the hose clamps I’m using. I was about to pull my petcocks apart because I thought they were leaking internally. I put my finger over the barb and turned them on and disproved that though. What appears to be happening is the clamp I’m using has developed a “barb” which is gouging the hose. I also think that even though these are small they are too wide. What does everyone else use? I’m not a fan of factory style squeeze clamps.
