A/C question: the green o-rings size

[rnln]

I want to replace all the o-rings with green o-rings for R134A. The problem is that Pelican website doesn't say which o-ring for which hose. Does anyone know which o-ring size goes to which hose?
Thanks.

If you go to your local auto parts store you can buy an assortment of the o-rings for a couple of bucks.

This.

For 5 or 6 bucks you can get every o-ring you need and many you don't need.

Thanks everyone.

As with PelicanPart, for future reference, here is what I just got form the rep...

R134a compatible o rings = HYDROGENATED NITRILE, aka HNBR or HSN.
Colors can be black, red, blue or green. In auto AC green is more common color.

For a 1984-1989, 911, stock system, from Pelican, you would order:

For hoses and components:

5 pcs of 999-707-247-40

3 pcs of 999-707-434-41

2 pcs of 999-707-251-40

For under compressor manifolds:

(4) 944-126-935-01

The only other o-rings you could replace would be compressor's
3 case o-rings, and the one in the nose seal, however for this you
would need a compressor seal kit. And, there is a small o-ring
where the expansion valves' external equalizer tube attaches
to the top evaporator outlet (which is usually not a problem child).
