Need o-ring specs for 2006 Altima 2.5 expansion valve

HI. I'm trying to replace the expansion valve on my 2006 Altima 2.5, but the supplied o-rings are failing. The original o-rings were much "fatter" than the new o-rings on the after market replacement; so much so that the lines do not fit snuggly into the expansion valve. I will be trying to get the o-rings from Nissan, but if they don't sell them separately, will have to find a different source. If the specs for the o-rings are available, could somebody please post them. Thanks...

I went by my local Nissan dealer this morning to purchase the o-rings, but they are not listed as a separate item. It was not clear if the o-rings would be included with the expansion valve, or if they would be with the hoses and evaporator assemblies. I believe that if I could get Nissan part numbers for the o-rings, that they would still be available for purchase, newer Nissan Altima models do show that the o-rings could be purchased separately. Does anybody know if the o-rings on newer Alitmas would be the same as my 2006 Altima? The part number for the expansion valve is different for 2006 and 2007+ Altimas. Thanks...
