O Ring oil for AC expansion valve

[NCLX450]

I am replacing my Evap core and expansion valve on my AC. What oil do I coat the new expansion valve O rings with? Thanks

I had read vegetable oil but I didn't know if that was better than PAG 100 for the AC. I assumed it was so tiny it didn't matter but want to check.

Ideally the same as will be used in the system. IIRC it takes ND-8/Pag 46 oil.

Silicone o-ring lube.

This is what did. Works well.
