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.
