I needed these to set up a DIY Baby Brine Shrimp Hatchery. Saw it on a YouTube by Joey from King of DIY channel. Cost and quality are good.

Easy to use in DIY Co2 setups. I’ve tried glueing air lines into bottle caps and could never get them to seal. This worked great.

I used this for my brimp shrimp hatchery and the quality is good for the price. It is able to suction and fit with the small tubes. The performance works well with a bro shrimp setup.

These bottle caps have done an amazing job fitting to any bottles that I tested them out on. Try not to use too much force as the caps could break, just a snug fit will do great and the caps will stay on the bottle no problem.The inline tubing I use can lift the entire bottle by itself because the locking mechanism is super tight. Perfect for my DIY CO2 2 bottle system.

Ordered because it was recommended for brine shrimp, it is not good for that. Holes too small.Performs great without leaking and bubbles are as expected.Great for adding CO2

They work pretty good for sugar water and yeast co2 production for planted aquariums. But beware don’t crank them down or they will crack at the top but it beats the hell out doing it with silicone and drilling holes in the cap.

Great idea but less than robust design. Practice degrades surprisingly rapidly. Cannot support the pressures for which intended. Poorly designed. Hose connection elements, both male and female, are not up to the task.
