Question about Solenoid O Rings

About a month ago I got new front air struts and rear bags from Westar. The car road great and it was nice not having the check air ride message come on at free way speeds.but over the last few weeks I've noticed my compressor running occasionally at traffic lights or when getting off the highway. I thought it was just because the car lowered itself, then I noticed that when I park the car and come back after about 3 or 4 hours the car is leaning to the drivers side. I checked and the drivers front strut is leaking down. Considering the strut is new but came with a used looking solenoid, I'm thinking either the solenoid it's self is leaking or when I removed the solenoid to hook it to the air line then put it in the strut maybe I caused the O rings to leak. I've heard of guys using A/C o rings to replace them. Does anyone know what size they are? Paying $20 for 6 O rings from one of the air strut companies seems stupid when I can get them all from the Autoparts store for a dollar or 2.

I'm not sure what the size is, but I know the last time I bought HNBR O-rings for A/C applications from the parts place (I think this instance it was Advance), they offered a kit with a variety of sizes and diameters for about $5. Might be worth a look...

Also - I at one point ordered rebuilt solenoids from American Air Suspension and when I received them, some kind of white grease (it wasn't as thick as lithium grease, possibly a silicone based grease?) was on the O-rings.

When I pulled the Solenoid out of the air strut it had dielectric grease on it, or at least it looked like it? What I did notice though was there was no big O ring in the strut or stuck to the solenoid when I pulled it out just the little ones.
