Somebody on this list (John Slade??)
had a turbo hose blow off many years ago. Lower pressure, but a
lot more square inches of it.

Hi Mark and Group:
Thanks for the head’s-up; actually I did
have not beaded the inter-connecting tubing but now that you
mention it, our chapter has a beading tool and I WILL DO
THAT. Yes, the radiator connections and the engine water pump
connections are beaded. So in between are 4 hose to tubing
joints that were double-clamped.
It was my engine that had the hose blow off
- but it was an oil hose (Twist-Tite fitting) not a radiator
hose. There’s a big difference between slowly increasing
pressure up to 20 lbs with smooth flowing coolant and rapid
pressure pulses in an oil line from an intermittent engine;
having said that, adding those beads is an extra margin of
safety I need. Thanks again to all …

Jeff,
This probably goes
without saying, but I have to ask anyway. I'm
assuming you put beads on all of the radiator
connections? Commercial radiators normally come with
beaded fittings. I'm more curious about the
sweep L's and other pieces of tubing in your system.
I am aware of at least one rotary a/c that made an
emergency landing after having a hose blow off in
flight. If not, Earl's Supply sells beading tools
that do a pretty fair job for the price.
