With these sturdy pumps, a partial vacuum of 86 mbar can be reached very quickly and easily. The vacuum can be controlled with just the index finger. Vacuum is set via a lever on the pump. The pumps reach full pressure with just two priming strokes. Removable cover on exhaust port and trigger to release vacuum, so the pump does not need to be disconnected from the partial vacuum line for venting. Hose connection for standard hoses with 6,4 mm internal diameter. Complete with 60 cm transparent plastic tube.
