63mm, G1/4, Delrin, black, 0-0.6 bar, 0-8.7 PSI Dr. Drop is an ingeniously simple pressure tester for your entire water cooling loop or for single components.
With an included air pump, a test pressure can be applied. A large manometer with a diameter of 63 mm allows for precise pressure readings. A second valve is included to discharge the pressure after testing.
The pressure tester has a G1/4 inner thread to be equipped with a hose fitting compatible to your preferred hose diameter.

Added bonus for bicyclists: The air pump fits car tire valves (Schrader) as well as French (Sclaverand) tyre valves. A pump holder (hole pattern like bottle holder) is included as well.
