A/C o-ring sizes 96 g20

[andre1038]

hi guys i got a 1996 g20 im switching the A/C compressor on it and i want to know what is the size of the o-rings for where the high side line and low side connect to the actually compressor itself.

for example is it a
13.7mm x 1.9mm or a 13.8mm x 2.5mm or some other size. i bought like a little kit that contains a lot of o-ring sizes i want to know since i don't want the r-134 to leak out due to a small o-ring

Cause on the FSM here on nico its say one is 16 and the other is size 12.

ok so i had to look up these nissan sizes based off a sentra fsm. I will show you the fsm that tells the o-ring sizes i think it doesn't matter what nissan year yours is as long its r-134 possibly it works for r12. Since my infiniti is a 1996 i think this might be a good reference guide
http://www.nicoclub.com/FSM/Sentra/2001_Sentra/ha.pdf you will see on page HA-5 what im talking about.

So here's the chart according to the FSM
nissan o-ring size / Diameter / width

8 / 6.8mm / 1.85mm
12/ 10.9mm / 2.43mm
16 / 13.6mm / 2.43mm
19/ 16.5mm / 2.43mm

the FSM also contains part numbers. Like i said this might be a good reference guide for those doing their own a/c compressor not sure maybe someone can chime in.
also if buying a compressor and it needs oil (usually new one comes with it already filled but lets say your getting a used one that some maybe missing just drain it and fill it with oil according to vehicles spec)
G20 is 6.8 oz of oil. now the fsm for the g20 calls for some oem oil (part # klh00-pagr0) but this reference guide below say PAG 100 is the same as that

Also has the type of oil for other nissan/infiniti vehicles plus more
