Upgrade Kit, Dr. Oligo, Change all 5 Gas valves on the Dr. Oligo from round Neptune Research valves for Main Gas, Over Pressure, Push, Hi drain and Close Vent to Pneumatic valves. This kit contains all the valves, fittings, tubing, brackets and wiring needed to convert a Dr. Oligo to use the new pneumatic valves. If you need individual valves see the individual valve part numbers in the related parts tab. If you are changing only one NR Gas valve to the new pneumatic valve and it is the first valve change you are making on your Dr. Oligo you will need the Pneumatic Valve Starter Kit along with the particular valve assembly that you need to change.
