I have a bag with about 700 double lip seals in it-- why would I buy any?

-------------------------
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

Could be the double lip has two lips, the second one is made out of Teflon.

Can buy special tools, I tend to wreck the old seal by using a Teletype hook puller, really the special tool is that thin plastic sleeve that protects the seal from being cut by sharp edges by the groove, a thin piece of scotch tape protects that as well as pushing the seal away from that groove when installing it. Refrigerant oil on the O'ring helps to slide it in.

I try not to clean the rust off the compressor shaft, need that to hold the hub on. The more rust, the better.

All depends on the application. If you are strictly speaking about newer GM seals I guess most could use the double lip seals as this topic was discussed many times now. Many imports still use single lip seals or even carbon seals. But I'm not a shaft seal expert. I use what is listed when the repair calls for a seal. I also understand that not all compressors are going to be repaired by changing a seal.

Here is the link to the compressor break down which list some of the different types of seals used.

History, dumbass Clinton picks Gore for a running mate giving him a little power, gets the EPA involved with MVAC with stiff fines only to techs, bans R-12, and says R-134a is friendly but still with stiff fines on techs if they release it.

GM was making a great ceramic seal for the A-6, but when all this BS started, came out with a cheap single lip seal that leaked like crazy. Ford comes out with leaky springlok couplers, Chrysler, Toyota, and Honda start using garbage grade aluminum in their evaporators or couples. They all use those stupid impossible to repair and leak like crazy quick coupling R-134a ports. Stiff fines on techs remained, my stupid state banned the sell of R-134a to anyone without EPA certification and charges an extra tax on it. But doesn't say a thing about the crap coming out on the market that leaks like crazy.

Least GM came out with a new double lip seal to help prevent those shaft leaks, first thing you notice is that your limited supply of refrigerant oil is splashing all over the place, a good guess as to how much to add.

Just a bit of history.
