D9'ers - Help prevent your a/c pipes corroding
Posted: Wed Jun 13, 2007 11:24 am
Further to Puggy's unfortunate a/c pipe failure (seen here in green)......

I thought I would look at mine and see if there was anything I could do to help prevent this happening.
I have spoken to my a/c man and he has tried several things over the years including copper grease! Apparently water and road salts etc become trapped between the rubber lined clip and the ali tubing and coupled with a bit of vibration they all conspire to corrode the tubing at the clip position.
The key to help prevent this is to repell water and provide a protective film on the ali tube.
So I set about doing this simple exercise:

I sprayed some WD40 silicone stuff directly and liberally onto the rubber.

A close up of the soaked rubbers, this should help repell any corrosives

I reckon if you do this, say, once a month then the pipe should never corrode here and you will save yourself some dollas.
Fin.
