So I have done a few horn installs and have always managed to fix leaks on no bigger than 1/2in ports so good that I can leave it for a week and it might loose 5 psi in a five gallon tank. but now i have a new tank that has 4 1in ports and I cant get them to stop leaking. all the other ports are not leaking its just the 1in ports.
I got them as tight as I could with thread tape on then and all but one is leaking like crazy. I can hear one leaking and when I put sopy water on the rest and they bubble like crazy at only 50psi.
I was about to take the fittings out and put more thread tape on them but thought I see if you guys knew if there was any thing better to use other than tread tape. and should I worry about over tightening the fittings.
i’ve had no leaks in the almost 3 years on my fittings with teflon you just have to know how to use it minimum of 3-4 wraps around the fitting and tighten it down make sure non of the teflon is over the opening of the fitting and make sure to wrap the teflon clockwise as if you were tightening a nut onto the fitting
Listen to Lance, we recommend Loctite too, besides there’s a possibility that pieces of the tape can get into the compressor when used on the suction side and screw things up. It could mess up a check valve on the discharge side too.
Teflon tape does seal, but it also comes apart, migrates throughout your system and does nasty things to pressure switches, valves and other orifices. A liquid sealant such as 545 does none of these things and does one thing well… SEALS!
FYI - Loctite 545 is anaerobic, meaning it cures in the absence of oxygen. Still, there should be some time given to allow a full cure. -Just NEVER tighten or loosen the fittings that are sealed with it again, or you will break the seal and a leak will develop.
If you have a ‘tap’ large enough to chase the threads in your tank; teflon tape will work…But most of us don’t have a tap this large in our tool boxes. Use Loctite and you’re golden. Especially if you’re running pressures higher than 150psi.
Was just wondering if you used pipe dope because it would be a lot harder to get clean.
I was just quoting out of that data sheet to clean the threads.
“1. For best performance, surfaces should be clean and free of grease.”
I think in one of their other tech sheets they mention using brake cleaner or similar.
Everybody seems to swear by the loctite 545. Did you put enough on?
