Hi kefah
I have used the heat gel and had no failures from overheating. Also it allows enough time to heat the pipe well enough to seal with welding. I had used wet rags in the past but also had leaks which had to be re welded.

Re: what are best method to cool reversing valve when install it
Interesting post, thanks Guys.
I did not even know this stuff existed.
One question though, as it evaporates. What's its shelf life like?

Not sure Grizzly but I had some in the back of the ute more than two years old. I wouldn't consider doing a four way valve without it.

Cool gel stuff looks quite good, i'll have a look about getting something and giving it a go.
In the past some old rags that are soaked with water, wrapped tightly around the valve has done the trick.
No problems yet...

Re: what are best method to cool reversing valve when install it
pyrokool is ok but the kool gel is better- last 4 way i did i had it submerged in a bucket and brazed the pipework onto it and then brazed onto the system with at least 12 inch of pipe on the tails so no dramas
did a carrier eurotop 4 way 1 3/8 stubbs with wet rags and used 6ltr spray doc full of ice and water and had a chimp keep the rag cold!-again no dramas

Re: what are best method to cool reversing valve when install it
been in for 3 month- note how the sticker on the body isnt scorched- also glo stick drops in the water, 2 others had allegedly repaired leaks on the system- small tubes had rubbed together so opted for the replacement option- and the quality of the braze is irrelevant as long as it doesnt leak as you only get a change to seal it before u refit it to the system
