    The spring clips also spread the tension better and more evenly around the hose.
    If you don't like trucks, stop buying stuff.

    You can get a dedicated tool for the spring clamps.

    It has gotten to a point where I now have a box of those clips, and I replace worm drives whenever I have one off. The other clip I’ve grown to love is the oetiker. Same deal, the spring action and smooth band is better for the hose, although they are a single use.

    Worm drive clamps are the JBweld of the clamp world. Universal, jack of all trades a master of none.
    Agree with all of that. But I thought there were specialised clamps for silicon. I wouldn't use worm drive, as they tend to cut the hoses, PITA.

    I have one, and I hate it. Clumsy, awkward, pos thing. But you can't do the remote clamps without it. But the bloody thing bites. But, you get what you pay for, I guess. I'm sure thee are better ones. Not naming, or shaming, the brand I have.....

    Those T-bolt ones, they're the ones I thought of. But I have a bunch of the spring type, and I doubt they'll cut the hoses, Just want to be sure. Never had these new fangled things in my day..

    Each to their own, but I've never seen testing to confirm this proposition.

    And if they ever start using spring clamps to locate and seal hydraulic and/or pneumatic hose fittings, then I'll switch to same line of thinking for coolant hoses too.
    And the reality is that the only reason manufacturers switched to spring clamps is cost. Quicker to fit them, and don't need a specialist tool to get the tension spot on.
    They certainly do not clamp better.

    I've changed all(or as many as I can reach) spring clamps to worm drives on my Td5s.

    I like Projectfarm's testing

    When I have to buy clamps, I tend to use the Norma/Sandvik (in Projectfarms video) style worm drives myself, but still have tons of std teeth style worm drives that don't tear up the hose. And for sure they can, and when they do that, it's time to change that old hose anyhow.
