    I use AWAB 316 SS hose clamps. Very good product. The automotive style
    hose clamps really have no business being on a boat.

            Good luck,

    >>>>I was doing a preliminary installation of a water-tank system today, and
    sure enough busted yet another stainless-steel hose clamp when tightening
    it up. Then I sat and thought about the matter, for the first time in my
    life. Why does this seem to happen so often?

    1) When I lived in the UK, we bought what we called "Jubilee clips" -- hose
    clamps -- but instead of having holes punched all the way through the clamp
    for the screw thread to grip (which obviously weakens the clamp),
    serrations were made on the outside of the clamp, making the clamp much
    stronger. These weren't stainless -- they were for automobile use. Is
    this design available in stainless-steel hose clamps? If so, who sells
    them?

    2) Is it in the nature of stainless-steel clamps that they are for all
    practical purposes fatally weakened after being used once and should be
    discarded?

    I've had these things fall apart in dark and mysterious areas of the
    boat. I know all about double-clamping, but nevertheless if it's the
    received wisdom of the list I'll stop re-using my old clamps and chuck 'em
    out. For a few bucks, it's just not worth the risk.
