When a leak occurs, the most common way to fix it is by using brass compression fittings. These are comprised of a valve body, a ferrule (a round copper ring), and a nut which screws to the valve body, compressing the ferrule as it is tightened.
How do you stop a brass union from leaking?
If the union is leaking from either solder joint, disconnect the union and heat the leaking joint to melt the solder. Slip the union off, spread new flux and re-solder it. If the union is joining copper and galvanized steel pipes, it should be a dielectric union.

Why do threaded fittings leak?

Professional plumbers apply pipe joint compound or thread tape to the fittings before connecting them to seal the joints and prevent leaks.
Can you use silicone as thread sealant?
yep. it does say use silicone sealer on threads.
How many times do you wrap Teflon tape?
You always want to wrap seal tape around threaded pipe fitting in a clockwise direction. In most cases for a new joint you should apply only two or three wraps of tape. On older fitting where the threads may be damaged you may consider adding a few more wraps, but keep the number of warps to a minimum.
How much does it cost to tighten brass fittings?
In general terms you want to aim for 2 to 3 full turns after hand tight. If it still feels loose, complete another full turn. A lot of plumbers will use both teflon tape and pipe dope. Depending on the thickness of the teflon tape you will want to use 3 to 6 wraps in the direction on the threads.
Will a slow leak seal itself?
A slow leak doesn’t actually seal itself. You need to locate the leak in the pipe first. You must shut off the valve to avoid any mess of water afterward. Once done, apply a pipe repair clamp to seal the leak.
Can you over tighten an fittings?
Ironically, tightening the fitting further will probably not stop the leak. In this case, overtightening has damaged the fitting. The threads may be damaged or even stripped, or the female fitting may have cracked.
What happens if you over tighten a compression fitting?
The tubing will bulge and stick inside of the fitting if the ferrules are overly secure. If you can’t disassemble the valve or fitting, it’s a good indicator that the connection is much too tight. The only thing to do in this instance is to remove and replace the fitting in question.
What happens if you over tighten plumbing?
If you tighten the fittings too much, you may strip the threads inside the fitting or on the outside of the pipe. This makes it more likely that a leak will develop, and it also increases the chance of a cracked or burst pipe in extreme weather or high water pressure. Lefty Loosey, Righty Tighty.

Is pipe thread sealant permanent?
Anaerobic thread sealant (pipe sealant) fills all of the voids or airspace between metal threads creating a permanent plastic seal. They do not shrink or relax over time.
