A/c sealant

[bertman]

Have developed a small leak on system,have had it checked with sniffer and uv light and cannot detect any leak.(very slow leak)
Guy has recomended a sealant which is put into system.I suppose acts like radweld for you your a/c system.
Any of you guys had any experience with this stuff,cannot remember the name of it,comes from the good old usofa.

Plus can anybody tell me where I can get the correct fitting to re gass on the compresser.Its not a standard fitting(not r12)on a 94 reg car.
Or what are the dimensions are on the fitting,and is it something I can get hold of.

migt be ok to use but i'd prefer to find the leak - it'll be an o-ring on the system somewhere. have you checked round the circuit behind the drivers side wheel arch liner?

If you do find it then halfords do a great o-ring kit for less than a tenner with alsorts of metric sizes - i resealed my aircon when i was putting it back together the other weekend on the parts which had been unbolted - hopefully it will be airtight

How many o rings are there in the system that could be replaced and where are they situated in the system
