Perfect for my linear air loop in my fishroom! These thread in really nicely after drilling the PVC with a 3/16” bit. If you’re building out a fishroom, buy several packs of these. Having plenty of extra on hand is always a good idea!

Very good quality I dont have it on pvc it works on air line to i could of got plastic ones but I love chrome looking stuff 👍👍

These work great; all came in looking and working as they should! Nothing but quality from Aquarium Co Op products and this is no different.

I’ve been using these for about half a year in my fish room and they’ve held up. I’ve received a couple that had the metal chipped on the tips where the airline attaches, but I used them anyway and don’t seem to be having any issues.

Been using it for my fry system for a few weeks now and no problems yet

I have 29 tanks set up. I run a central air pump and I use these valves for all my drops. The work great and east to install. Corey had some great youtubes on how to do it. Highly recommend only air vavels I use.

This is first time I’ve used these and went this route having 28 tanks on one air system. Easy to put in and just follow what Cory says with check valves and a air adjuster down low to each tank. Works great. I will be buying more stuff from Aquarium Co-Op. I’m hoping to offer Cory products in my store soon.

These are very very easy to install. Appear to be high quality. Love it!

Hey Cory love ur YouTube channel & im so glad u can ship to OZ. I received my package in perfect CONDITION & extremely fast SOOOO VERY HAPPY & the quality of the products is outstanding thanks heaps mate 🇦🇺 looking forward to more future orders with u guys. Was a pleasure catches on the next TUBE Vid 👍

These are sturdy, well-built little valves. However, out of the 5 packages I purchased, a single valve was off, and had a different thread size / stem diameter. Not a big deal, i just had to tap a different size hole for it in my air manifold. I'm guessing that one valve was an odd-ball that slipped passed quality control on the manufacturer's side. Regardless I still highly recommend these.

I am so glad that I added these when I got my pump. Take sink into the PVC so easy. Originally my brother-in-law was trying to talk me into something from the hardware store. He was thanking me after the set up that I got these guys.

makes balancing your air output easy no more rubber bands lol

They work great and out of 60 plus that we bought there were no issues with any of them.

Been setting up a new tank and picked up a bunch of new things from aquarium co-op including new air pumps ( that are fantastic themselves!) and these valves to further refine how much air is going through my tank. They work great. Easy plug and play with some air line and check valves. Let's me really control what's coming out of my sponge filter air stone and the under gravel filter in another tank. I've bought two packs just to have extra on hand.

This is a game changer and the quality is great too. They're strong and durable. So much better than the cheap ones you find in stores. Plus it comes with several. I love all the products from Aquarium Co-Op trust me you will too! Top tier products with amazing prices you can't go wrong! This company and owner strive to provide the best products as well as valuable information so you can be a successful fish hobbyist. Thanks Aquarium Co-Op for providing the best products! Oh and the customer service is by far the best too.

Installed the valves in thick wall PVC. Drilled the holes and then tapped threads in the PVC. Screwed the valves into the holes. No air leakage around the holes.

Exactly as advertised, no complaints.

Great for making an air loop nice and sturdy smooth valve

We are setting up a fish room. They are little enough to not be bulky on the pvc pipe.

Used these when I set up my central air loop. They self tap into pvc (I used schedule 40), fit nice and snug and show no sign of leaks. I plan to buy more!

All valves had a clean finish out of the packaging. The finish is durable throughout the drilling step. The ball valve is smooth and allows me to dial the air flow to each one.

These are pretty good and well made.
The thread is taper so it's self treading unlike some on the market.
It's also a fair price

They work. Have installed over 60 of these and haven't had a problem with any of them. I did have to go up a bit size to 13/64 when installing but it worked perfectly in pvc with no glue.

I tapped a 3/4-in pipe for my linear air piston pump and I screwed these right in worked perfectly

Two biggest things. First is durability. Just like any size or type of valve in or on the market, SS is the way to go for this application. Second is the look of course. Take it to the next level please!

Have used the plastic Ziss 💯 good, But the metal one's are awesome you can thread them in a proper sized manifold hole 😜
