Help! RV2 compressor blew new shaft seal

Hi Gary,

For an empty RV-2 system, I would use 10 to 11 oz. of something like BVA 100 ester glo. The oil is then compatible with both R-12 and R-134A. It also contains a U/V dye to help track down any future leaks.

Operating pressures would be around 25 to 28 pounds on the suction side with R-12 and a bit lower with R-134A. Discharge pressures really depend on ambient air temperatures and how hard the system is working removing heat, I would expect 125 to 225 pounds with R-12 and slightly higher with R-134A. R-134A does run at higher discharge pressures.

Good luck on the new seal, hope it holds for a long time.
