EXACTLY WHAT I NEEDED
I NEEDED TO MAKE SOME ALUMINUM ELBOWS THAT WHEN FROM WELD ON, ON ONE END TO A NPT COUPLING ON THE OTHER. FOUND THESE ON BOYD. THESE THINGS ARE NICE AND THICK! THEY LOOK BETTER THAN THE GARBAGE ELBOWS. ITS A SHAME THEY WILL BE GOING UNDER A TRUCK WHERE NO ONE CAN SEE THEM. IF I NEED ANY OTHER ALUMINUM PRODUCTS I WILL BE LOOKING HERE FIRST.

Aluminum NPT Half Coupling
bought a couple of the half couplings to weld onto a device and they were very well made and had no issues at all. Fast shipping also!
