It connects airlines like you wouldn't believe. Yessir. This bad daddy can connect one airline to, get this, a whole 'nother airline. Ooh dang.

Good quality plastic airline connectors; using them to spice line and run air out of pvc. They work as expected. Something everyone should have a couple of extra of in the fish room.

I needed an extra 3 feet for my air hose and this is what I used. Nice to keep on hand if you ever cut a line too short.

I use these when replacing the hard airline tubing in the aquariums, snip off the hard dried out airline and splice in only replacing the hard dried out portion

Works as intended.

Great when you don't have any spare/scrap rigid airline tubing handy to crop into connectors!

Does the job

Overall, they work pretty well, no leaks, and they seem to be decent quality

Great connecters at a great price!

I worked to have everything ready for a new 40 gallon aquarium- I bought plants from Corey and dropped them into various tanks so they could begin growing, I bought filters, and air pumps, etc. When I desperately needed airline connectors AND airline tubing I realized I didn’t have equipment from Corey. I placed a quick order and received it within 3 days. I realize how much better Corey’s products are than all others. It’s just not worth trying Amazon products as backups.

Not much to say for what it is, but it does what it needs to do!

Good product and quality is good too. Better than pet store!

These were perfect to make a circle out of air line tubing so I could keep my red root floater together. Great for this and air line extensions.

Straight Airline Connectors

They arebthe perfect size and work great.

Work’s great

These connectors are extremely smooth hard plastic and will easily slip breaking the connection on some applications (e.g. soft silicone tubing and the black airline tubing sold by Aquarium Co-Op)

Aquarium Co-op straightline airline connector has a neat and sturdy construction.
Tight fit with Aquiarium Co-op airline tubing to allow for reaching a longer distance.
Does its job very well.

Straight Airline Connectors

These little gems are hard to find! No, not couplers, couplings of this strength and durability. Give a retired master plumber a fish tank room and he will find all the best parts to assemble!

My bubblers came with 25 foot tubing. Before I had to coil extra up so could change configuration in future. Now can cut to length need and know can change mind and reconnect more tubing as need.

I’m a big fan of Aquarium Co-Op ever since I started learning how to properly maintain an aquarium. Their products never disappoint and these work great as well.

Simple, basic, just what you asked for!

Always a smooth transaction!

I had to trim an inch of air line to get a tight fit but that's only because my other air connection was a bit oversized and stretched out the air tube. These do the job at a much lower price than you'll find them for locally.

These are simple , but work great to connect tubing

These are exactly what they say, not fancy but gets the job done, have purchased dozens of these from Co-op and never had a defect or failure.

Work very well. Drill a 3/16 hole into the pvc pipe.
then attach the valve to the drill bit, use the drill, and it will thread it into the pvc pipe

The quality of these airline connectors is really good and price is just right. Will be buying again shortly. Currently using to make floating feeder and plant rings with a bit of the black airline tubing.

Worked great, so many resources to follow.
