Title: ideal 55 slider tub with evaporator Post by: r500 on April 25, 2012, 07:29:36 pm Does any one know what the black nasty stuff that is around the evaporator tubes on the tub of a ideal slider and what purpose it serves ?
After repairing all rust and holes should I install calking around the tubes like that black stuff was? That stuff is like roofing cement it gets every where and it does not come off very easy. What is it? Title: Re: ideal 55 slider tub with evaporator Post by: Yarochrehc on April 25, 2012, 09:20:45 pm It's a type of insulation.
Title: Re: ideal 55 slider tub with evaporator Post by: johnieG on April 25, 2012, 09:43:13 pm it's a Tar like substance used as caulking to hold the tubing in place, (it's was called bitumen), it has some minor insulating quality, but mostly it was the "hot-glue" of it's day, later they, (Ideal Corp) stopped using it & switched to soldering the lines in place to secure them to the tank, on some late production models they finally were using spot-welded brackets that were bent around the tubing to fasten it to the tanks walls ( think of this method as metal tie-wraps)
Fun stuff... :tounge: |
