Review on PTNHZ 63 5Mm Aluminum Billet Filler by Aquarium Lanter

I used this to build a small diesel tank for the auxiliary heating. I'm not a big TIG welder but I still managed to weld it with no leaks. Tested the tank under pressure to 40psi to find leaks (yes I've had a few, again not a very good welder) but I will say there weren't any in the lid. Beautifully welded. The surface finish is so good that the O-ring in the lid is tight. I'll probably have to drill a tiny hole in the threads so I can turn this sealed cap into a vented one. No problem and I would use it again.
