Reply:Looks like it should hold depending on the application. Is it some sort of intake screen for a pump or something?Seen an a/c contractor that tried to do their own mechanical piping run flux cored wire around a 4"-3" threaded reducing coupling because the pliers could not tighten it up enough to stop the leak.   There was also no teflon tape or pipe dope.We were called to fix it and found out the threaded nipple was about 6" long and machine threaded all the way from one side, no wonder it leaked!!! Made new connections using weld neck fittings and those guys said "whell that's the same thing we did, can we help".TOO MANY TOOLS & NO MORE SPACE
Reply:Large bore crack pipe?GravelThe difference between theory and practice is that in theory there is no difference.

Reply:A one inch black steel coupling would weld fine. Much better then galvanized.
Reply:Is black steel and black iron the same thing? I got this from Home Depot 5 minutes before they closed. I should have waited to go to Parkrose hardware, they have a real nice collection
Reply:If it's for a recirculation system in a cooler, I'd probably use brass pipe and fittings - no corrosion possible.Keep that system as clean as possible.Brass screen on brass pipe maybe easier.Next time I'd make the fitting so you can change and replace the screen.
Reply:I can blow the crap off the screen.
