PVC Bulkhead Fitting Double Threaded Bulkhead Water Tank Connector for Rain Barrels, Aquariums, Water Tanks, Tubs, Pools, Spigot, Black, 3/4 Inch Male 1/2 Inch Female (4 Pieces)

Got these to link up several water barrels. It is tricky to get the fitting installed unless you have a water barrel whose top completely comes off. I did not, but go check out YouTube where you will find some great tutorials on how to make it work anyways. These did the trick and I am very happy with them.

This product worked well for my rain barrels. The price was great as well. I used this for the overflow.

It took quite a while to figure out what type of threads are used on this fitting. They are NPS! Not NPT. They don't need to be NPT because of the gaskets, which make this a waterproof seal. These also aren't really meant to be attached to curved surfaces, either. You can probably get away with it on large-diameter tanks, but definitely not on small ones. Ensure that whatever fitting screws onto this one also has a gasket at the end, or it won't be waterproof. Seems sturdy enough for most applications.

Well made and work as advertised.

Found these as the best replacement for my drain plug in my pond prowler boat. The one that came with my boat broke. Installed this and it works perfectly without any leaks. I’m sure it works great for what it was designed for but if you need it for your boat, it’s a perfect fit.

As expected.

Often cheaper bulkhead fittings are made of fairly brittle plastic. Not these. The are made of a more durable plastic that instills confidence. They easily seal with no leaks.

Works great on plastic containers but not so much on wood. I tried to use it on a plywood board and it doesn't fit. The threads don't come all the way to the end leaving it too short to use
