If a valve is over-tightened, it deforms the tubing and the connection, as mentioned earlier. These deformities create cracks and gaps where the fluid can begin leaking out.
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.
Can you over tighten an O ring?
Over tightening the fitting will make the threads deform and yield which will cause them to lose adequate clamping force or load on the seating area. Severe conditions and over extending operation of the system can cause additional yielding, resulting in unwanted leak points.
Can you over tighten water supply line?
Do not overtighten the supply line.
Screwing a supply line on too tight is one of the worst things you can do. Such overtightening will cause the metal threads inside of the line to become warped, making it much easier for water to slip past. It may also damage the rubber O-rings inside of the line.
How do you fix a leaking plastic pipe joint?
Epoxy. Repair epoxy is putty or viscous liquid that can be used to repair pipe leaks on PVC and its joints. To repair your pipe or joint using epoxy, first clean and dry the damaged area, ensuring water can’t reach the affected area. If necessary, mix the putty or liquid according to the manufacturer’s directions.
What happens if you over tighten plumbing?
Over-tightening will also warp the rubber fittings inside the pipes over time, which can increase the risk of leaks. Turn a plumbing fitting only until you feel it tighten, then stop. Continuing to turn past that point can lead to trouble.
Why is my O-ring leaking?
If YES, then most likely causes of leakage: 1. The O-ring is not being squeezed enough to ensure reliable sealing. 2. The surface finish of the mating parts is too rough to attain a good seal, or the metal surface is scratched.

How tight should a pipe be?
As a general guideline, after hand-tight engagement, tighten 2-3 full turns for sizes up to 1 inches for NPT fittings. You should have between 3.5 and 6 engaged threads. Any number outside of this range may indicate either under or over tightening of the joint or out of tolerance threads.

How tight should O-ring?
To provide an effective seal, the O-ring’s inside diameter (I.D.) must be smaller than the piston groove diameter, so that the O-ring is slightly stretched, fitting snugly in the groove. This stretch should be between 1%-5% with 2% as the ideal in most applications. A stretch greater than 5% is not recommended.

How many wraps of Teflon tape should I use?
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.
Why is my compression valve leaking?
Over tightening a compression fitting can also cause the fitting to leak. When tightening up the compression fitting, only turn your tool until you feel resistance.
