The present design for a ball valve incorporates mating saddle seals that wrap around the valve ball and fill the valve chamber surrounding the valve ball. The sealing saddles cooperate with the existing ball valve seals upstream and downstream of the valve ball. This configuration is suitable for retrofitting existing removable ball valves currently used by technicians and may be included in new valves as well.

A vacuum pump system includes an air-cooled, O-ring sealed vacuum pump and an oil management system with an LED illuminated clear tank for observation of the oil condition as well as a large oil inlet and outlet for rapid and safe oil changes while the pump is operating. The oil management system is also configured to prevent oil from the sump from being drawn into an evacuated AC/R system when the pump is stopped and the intake ports are not sealed from the high vacuum AC/R system. The oil management system includes a preferential vacuum relief system that allows air instead of the oil from the sump to be drawn back into the evacuated lines.
