Good quality BUT ...
Good quality BUT the outside nut is LEFT HAND THREAD !!! So you can't connect 1&1/4" pipe to the outside of bung connector, can only use i side of 1". I can not understand why they use LEFT HAND THREADS, instead of the standard right hand threads, this is the reason for 3 stars.

Does What They're Supposed To
Used these to plumb together two 300 gallon IBC totes into my water change/water mixing station for my reef tanks. Solid so far and no leaks.

They work!
These are worth the money, they seal well and easy to install. Just drill a hole and put in and tighten nut but don't over tighten. Made well.
