Threaded well .
Made in the USA
Great. Wish you had one that was half the length for bowl to bowl connecting but this is great for chamber connections.
This is a nice product.A little too large.
I bought it to go with the Lil Nickel Pipe and it works great. It was worth every penny
"If you are using it to connect 2 bowls together to make a chamber the threads are about 1/8 inch too long... you could fill that space using one of the big ""O"" rings they sell on this site."
