Slowpoke, I use Never Sieze on assembly because of that problem with dissimilar metals. I put teflon tape (on pipe threads) with a little Never Sieze to help with that metal corrosion problem.
But then again, I also use Nair hair removal products as a hair styling jell/moose (on my sleeping brother as a kid), so what the heck do I know!!

 

Arr yes ...a regular Plumbing issue !! and for those who still think I sit here 24x7 ...

I am still a Lic Plumbing contractor , that works nearly every day at least all the ones that I can't dodge... :-)

Electrolysis is the word for this dissimilar metal / hot water / static electricity damage ...
It is what kills most H/water systems and boilers that I charge a veritable chittt!! load to replace . LOL

and hot engine water cooling systems on cars and bikes

 

You only get galvanic corrosion if gal comes in contact with zinc or other dissimilar metals...

In Aus, on our modern plumbing systems and on our CBR1000F's , no gal exists mate ...that I know of

So yer ... Electrolysis's the culprit

Yer ...right ...
You will keep mate ..... LOL

 

Shadow, "galvanic corrosion" and Steve, "Electrolysis." Rocket science must be a CBR-F way of life.... Shadow, I agree with Steve, if you want to get rid of hair on your legs, one must do electrolysis.... And Steve, I agree with Shadow, if one plays with volcanos, one gets (v)galvanic corrosion. There, that settles that....
Shadow, Steve, you are both right on the Jimmy Black. Out in the desert, it is so dry that even Jimmy Black will evaporate, so the rest of us brothers can wait, the Jimmy Black would be wasted if left to sit for a while!!!
Since the T-Stat housing is made of mainly Aluminum and when Alummmm is exposed to weather for a long time it grows fuzzy stuff on it, does that mean the fuzzy stuff is called Gerbal-lysis-ic corrosion? In other words, fuzzy little gerbal *****..
I think it is time for a Captain Morgan Jamaica Rum in with the coke, Jimmy Black and a JD fellas....
