Could be milled better. Could not stop leaks no matter how much teflon tape I used.Can’t speak for anything other than the fit and finish. It looks very well made for $13. Extremely happy to find this 1” to 1/4” tee. Couldn’t find this from my local plumbing supply store. Added pic since stock images didn’t show this one.Not too happy about this one, waited for this as it was the last part I needed to complete a glycol loop. 1" NPT threaded smooth and fine, but the two 3/4" NPT got rough at only a half thread in. Threads look like they may not have had the final machining operation? Since this was the last part on my entire system that I've been waiting weeks to fire up, I decided to put a wrench on it and tighten the copper 3/4" adapters into this... still only made it 3 or 4 threads.Assembled my system and it has a minor leak (pressurized with co2) out of both sides. Going to pressure test with water now, but I'm guessing it'll still leak and I'll probably just cover the whole thing with 3 feet of epoxy and be done with it. Such a hassleI bought two 1/2 x 1/2 x 1/4 tees. They worked OK, but I don't think there was a single port on either of them where the pipe threads were aligned with body of the tee - so the pipes screwed in go off at crazy angles. This is OK for flexible applications, but for rigid pipe applications, look for a manufacturer with much better quality control.The threads were slightly miscut on one end, making it impossible to get a leak-free fit even with the proper amount of tape. I ended up having to JB Weld it.3/4 bullnose tee. Hard to find part. Sent quickly. Worked like it should. Can't ask for more.World Class Quality.It’s a brass tee
