Pawfly 2-Way Aquarium Air Flow Control Lever Valve Manifold for Air Pumps Multi-port Distributor Splitter with 1 Non-return Check Valve T-shape & Straight Connectors and 4 Suction Cup Clips

A little fiddly to adjust but they do not leak and work really well on my co2 line.

The taps are easy to connect to a standard size fish tank air line. I use this to run multiple sponge filters in my breeder tanks and can turn filters on or off just with the turn of the tap. I use several taps to run new airlines to many tanks or just splitting how much air goes to each filter or air stone that has been set up.The quality of the taps and great and simple, and there is nothing complicated about them, They are nice and shiny and give that little professional touch to the fish room.I would recommend these to people who are looking for great quality taps to set multiple airlines up to fish tanks or even just to control the air flow to your filters or air stones.

Does the job I needed them to do

Perfect for controlling speed of Mamod steam toys. You must ream out chrome to solder your pipes on. Very pleased 😊

A great improvement over the old 'gang-valves', and make air regulation easy and accurate.

Complete waste of money doesn't even work. Very disappointing.

Makes controlling air flow a breeze.

Great quality
