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.
