Hello, I am fixing an ac leak on the 94 ls400, the Freon as been evacuated, and I have found the leak. I need two o rings for these two lines, it appears Lexus doesn’t sell and has never sold replacement o rings for this, neither has denso, which makes no sense.. does this mean all I can do is use generic o ring kits from parts stores? That makes no sense and doesn’t seem right, but oh well. Wondering if anyone could help me out, I’m just kinda lost there. I bought a 270 piece HNBR O ring assortment, but I can’t tell if they are the same exact o ring sizes. And what are these two lines called? Thanks
How to determine o-ring size and parts needed

The AC Delco Gold Kit will work.
you can buy an o-ring kit for that exact car at any auto parts store. Often o-rings on cars are a mix of common and not common sizes .
You first need to id the specific refrigerant used and then spec out O-rings with a compatible material.
If it's R-22, it's going to be different than R-12.
And eliminate the oil leak, because it's possible the O-ring material doesn't play nice with motor oil.

First, the refrigerant lines coming off the compressor are suction and discharge lines. The suction line carries low pressure gas from the evaporator to the compressor (sometimes through an accumulator). The discharge line carries high pressure gas between the compressor and condenser.
Second, I often find the O-ring sizes by checking the replacement parts catalog. For instance, the suction line for your car is Four Seasons part number 55647. This line comes with two (2) HNBR O-rings, Four Seasons part number 24682. The data on this O-ring is as follows:
Can't find a discharge hose for your car, sorry.

Just throwing this out there. Everything you wanted to know about o-rings can be found in this "handbook".
