AQUANEAT 20pcs Aquarium 1 Way Thread Valves, Air Flow Control Valves, Manifolds Distributor for Pumps Fish Room Air Systems

Haven’t used for too long but in the few months I’ve had them they work great and seem to be decent quality

So much better value than trying to buy these at your local fish shop.

Used for home made hydroponic set up. Handles water and air.

They are pretty decent air valves. I recently installed 40 of them while moving my fishroom. They don't feel as well made as the AV1E available from Jehmco (for example, the levers aren't attached well, and during installation one fell off and I expect more will do the same over time).

Ordered three packs just in case one broke. I have not had one break. I use a 3/16 bit. I do not believe there is any leaks. Nothing was add to seal the valve. Just screwed into pvc. Have to use a drill, you will be there for ever if you try to do it by hand.

Bought to make a PVC air manifold for aquariums. Easy to "drill into" PVC. Drill a hole slightly smaller than the threaded end of the valve the "chuck" the valve into the drill and slowly drill it into the hole. No need to "tap" the hole in PVC. It allows a single air pump for, in my case, 6 aquariums and 12 valves. I used 2" PVC for plenty of volume so little fluctuation when adjusting the flow of each valve.

Muy bueno para lo que se usa

Very nice holding up so far
