These are a quick way of making a permanent connection when connecting hoses together. I take a closer look at them and walk through how to use them. They are also known as “Ear clamps” since there’s the “ear” part that you use to crimp them.
You can get the whole set from Amazon:
It has everything you need to get started.
The final result from using these to replace the old worm-drive clamps I think looks pretty darn good.
One of the big advantages is that the clamp on the back of the hose takes up a lot less space than the screw type and it’s not rubbing up against things. I’m way less likely to have issues around that in the future.
