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

Well made valves.

I've been using these for a few months now with my shrimp rack, and I just upgraded to a larger centralized air pump. I have yet to have any problems with these valves. A 3/16" drill bit does the job for drilling holes in the PVC, and then just put the hose part of the valve in the chuck and screw it in. I haven't had any leaks and was able to reuse 100% of the valves when I switched to a bigger system. Will definitely be ordering more of these as the fish room grows.

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).

Works great, anyone looking for the drill/tap this fits perfectly: Drill America m6 x .75 Tap and... https://www.amazon.com/dp/B0CTW9GWZL?ref=ppx_pop_mob_ap_share

I used these in pvc tubing on my rack in my fish room. Didn't have any issues with quality and they isolate air to hoses I'm not using. No leaks at all.

I have purchased at least 6-7 sets of these for my fish room. These are fantastic valves. After a year of use I see nothing wrong with them still.

I’ve had zero issues with any of these valves and after installing 100+ I would say a 3/16 drill bit gives you a much tighter fit then everyone here suggesting the 13/64 size bit. 13/64 will work but was not as snug of a fit.
