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. :bowdown:

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? :shrug:

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.

Just done mine, Aircon man said just clean and fit 😎
