guessing its something you need yesterday, since the part is available for about a dollar?
Purchased a box of of rings from a specialised auto a/c shop down town just after I posted this. I managed to find a Speedtoys thread with most sizes itemised that was helpful but the O ring in the low pressure switch was not mentioned.
Hopefully I do not need to change this item when changing out the filter drier unit
Fred, I get 13 x 10 x 1.5 on the used one I have here, but in my stash of new o-rings, the one I'd choose would be 13x9 x 2. The step in the fitting on the receiver drier is 1.5 mm deep, so I think the old one has been crushed down to that depth. OD of the threads on the low pressure switch is 9.4 mm.

Rob,
Excellent- thanks for that. Got a box with a pile of the little buggers this afternoon- I assume they are all to standard commonly used sizes but...?
Looks as though I am not in quite the hurry I expected to be as I did a vacuum test and the leakage rate is excessive- probably the compressor as there was a small accumulation under the body- bummer!
