Default Air Con O Rings

Hi all.

After rebuilding my 3 speed cooling fan - which now works on all speeds - I'm wondering about the O rings on the Air Con where it connects on the driver's side of the rad.

I'll be getting new rings and they need to be lubed for reassembly. RAVE 82-11 #8.

Now, RAVE says "clean refrigerant oil" but a bit of reading around the subject has left me baffled. Some say absolutely not refrigerant oil, some say silicon oil, some mineral oil and about the only one I haven't found is snake oil .

There's something called Nylog Blue which crops up regularly https://www.derbyshire-refrigeration...hread-sealant/

Obviously I only need a very small amount.

Some advice from the great and good would be appreciated.

TIA.

Hi Andy,

Do you think it's likely that the seals specifically for an air conditioning system would be made from a material which isn't compatible with its oil and furthermore that MG Rover would then deliberately recommend its use?

I wouldn't fret too much about it Andy. I've never known an air conditioning seal to disintegrate over 35 years of doing my own repairs.

Hi Andy
I presume you are talking about the condenser O-rings and not the compressor O-rings ?

IF the condenser O-rings then use a little red rubber grease on them.

If it's the compressor O-rings then just use the oil that's in the compressor dip your finger into the hole and smear the oil around the O-ring

Changed mine out a few days ago due to a leak, i am about to strip it down sometime today.

Cheers mate.

Yes, the condenser ones from when the fan came off.

And I've already got a tin of red rubber grease, so all's good.
