SENSTREE Tube Bulkhead Connector Push Fit Quick Connect for RO Water Reverse Osmosis System (Pack of 5) (1/4" Tube Bulkhead Connector)

I use these as quick connect/disconnect fittings for hydroponic bins, so I can easily detach them from the air system and move them to another space. They work great, and it's so much easier than pulling all the air stones out and making a big mess.

As the product description sais.... it's for 1/4 inch tubing. - During installation, it is important to cut the end flush,clean and square. if there is _any_ burr, or the tube gets mis-shaped (oval, and not circular), then you can potentially have leakage. Obviously, if you're working with a 6mm tube, which can be mistaken easily, it won't fit!

They connect easily enough and the bulkhead works, but of the two 1/4" tubing brands I have one was too thick to fit and the other was too thin and leaked.

Very easy to install and perfect for buckets. Good price for the number you get.

No gasket or seal, requires silicone or it will leak. Only received half of the retaining clips. Can't recommend it.
