Can you feel a bead at all on these?

I need to do something before they release themselves when I least expect it.

Off topic but sort of in as well.. Demonstrates the importance of Swages.

Rick do you remember those big Grey Email Package units in days of yore. Can't recall the models now. SU rings a bell. Water cooled from a Marley Tower on the roof.

Picture this if you will.
Just before Xmas one year we contracted a respected Plumber (1st mistake) to replace all hoses on these water cooled units so they would be reliable for the Grosvenor Hotel big Xmas Lunch in Adel.


Came the day, enjoying my Lunch, phone rang. "Grosvenor here, we are being flooded out in the dining room" (& I do mean flooded)



Get there to find the new hoses had blown off the straight section of smooth 2" HD copper pipe at the WC condensers 3 out of 6 units. Carpeted floor was awash with customers grabbing their dinner plates & moving to a safer area still with cutlery in hands. There was uproar in the Dining Room & the clients would have paid a Mottza for lunch.

There was an 8HP or 10hp pump still draining the Marley at a rate of knots so you can imagine the scene.


You've guessed it. No swage on any of the the copper pipes. This hadn't been a problem before & as the factory hadn't swaged the pipes but used a type of BOSTIK to hold the hoses on against pump pressure. It had all set nicely in it's previous untouched life. But replacing with new hoses created a minor problem.

It didn't need mechanical fittings, just a swage with a Pipe Expander. & clamps (2) per joint. 24 total


All ended well. The Grosv. wasn.t happy, the customers wanted their dosh back & the carpet was ****ed & had to be replaced & the Plumber learnt a lesson. So, a good day really in the scheme of things.


Oh yes one small point. The Grosvenor then was owned by the family whose head was my employers Chairman of the Board.

Big insurance claim for the Plumber though.


Ah, Happy Days.

The original are swaged and a quickfit onto the cooler. For aftermarket ATF coolers the regular push the pipe over a bead and hose clamp are not strong enough, they need to be multibarb pirtek type fittings to hold.
