What are folks using for infusion hose clamps?

I have been using the standard vise grip clamps to open and close the infusion lines. The benefits of these is that they are easy to take on and off and have a good grip. The downside is that they don’t completely seal the hose sometimes and can damage the line. I have also tried some automotive hose pinch clamps like these -
But, they don’t really seem to get a good seal and when you are in a hurry sometimes, the locking mechanism is a real PITA.

These little cheapy clamps work well enough but are slow to open and close.

These look promising. Anyone try these or have other suggestions?

I used to use a bolt and a piece of tacky tape until I saw Evan’s infusion video. $15.99 for a set of Crafstman sheet metal pliers. These things are AWESOME!!

Are you talking about these?

I used $4 harbor freight ones

Yeah, those are the ones!!

Ditto the $4 Harbour Freight sheet metal pliers. I grind the ends to a radius 'cause sometimes they are too sharp out of the box.

I just bought a couple sets from there too but had to buy the welding ones too as a set. I was going to swap those out to get 2x in one box, but with my luck, I’d get caught! I can just see it now in Composite News: teacher caught red handed! :lol:
