Aquarium Air Pump Splitter 2-Way/3-Way/4-Way/5-Way Air Flow Control Lever Valve & Non-Return Check Valves & Suction Cups for Fish Tank Airline Air Tube Hose

Work much better than plastic taps !!

Great pack all accessories for air pump, all you'll need

Did exactly what I needed. The black rubber nub can go on either side of the metal air intake, so it sits nicely whichever side of the tank your stuff is on. The valves do a good job limiting and/or blocking air however you choose to adjust them. They both would completely shut off the air without leaking if I chose. And I haven't tested the water backflow valves, but they seem to effectively allow air to go one direction but not the other. The connector ends are the right size for a super tight fit around my standard airline tubing. It was actually really hard to shove them on, since the tubing I have is really stiff, but they all worked!

This valve unit was used as a steam diverter for three small steam engines. It works great. Keep it lubricated.

Tudo OK
