Place the compression nut in the jaws of a second crescent wrench, tightening the wrench to the nut.
Remove both wrenches.
Can compression fittings be removed? You usually have to cut it off. Shut off the water to the pipe from which you are going to remove the compression fitting. Hold the male end of the fitting steady with a pair of adjustable pliers. Turn the compression nut counterclockwise relative to the male part of the fitting with another pair of adjustable pliers.
How do you remove plastic fittings? Hold the pipe with one pair of slip-joint pliers and use another pair of slip-joint pliers to turn the fitting.
As you turn the fitting, pull it away from the pipe.
If the fitting does not pull off, heat the area with the hair dryer for another four to five minutes and try again.

How do you remove a compression fitting valve?
To remove a compression-style valve, hold the valve body with an adjustable or open-end wrench, or a slip-joint pliers.
Grab the compression nut with another wrench and turn it clockwise to loosen it.
Then pull the valve off the copper tubing.
Next, remove the old compression sleeve and nut.
Can you reuse plastic compression fittings?
Because of the function of hydraulic fluid, plastic fittings may never be reused,reusing these connectors may lead to a leak due to plastic deformation. They will not fit as tightly as they were at the original time.
Can you reuse brass compression fittings?
Reusable Compression Fittings: They are safe to be reused and apply to half the movement of the pipe outward from the fitting. In hydraulic process, compression fittings basically assure some secure fit in pipe connections.
How does a compression fitting work?
A compression fitting is a type of coupling used to connect two pipes or a pipe to a fixture or valve. As the nut is tightened, the compression ring is pressed into the seat, causing it to compress against the pipe and the compression nut, providing a watertight connection.

Removing Plastic Plumbing Fittings
Step 1 – Use the Hair Dryer to Heat the Glue.
Using the hair dryer on the hottest setting available, apply heat to the plastic fitting.
Step 2 – Pull Away the Fitting.
Hold the pipe using a pair of slip-joint pliers.
How are compression fittings sized?
To measure a threaded fitting, measure the thread diameter at the widest point across the threads.
For a non-threaded fitting, measure the actual insert opening diameter or tube being inserted into the compression sleeve.
How often should shut off valves be replaced?
about 8-10 years
The compression aspect of the valve usually fails to work after about 8-10 years.
This usually fails either with wear and tear or simply because it’s old and has been in the home for a long time.
It’s a smart idea to have these values upgraded with reliable ones.
How does a PVC compression fitting work?
A compression fitting may be constructed of PVC or metal.
A compression fitting works by using a rubber gasket.
This gasket is compressed against the existing pipe when you tighten a nut on the end of the fitting.
This makes a leak-free seal without the need to thread, glue, or solder the pipe connection.
Should you use Teflon tape on compression fittings?
Thread sealants such as joint compound (pipe dope or thread seal tape such as PTFE tape) are unnecessary on compression fitting threads, as it is not the thread that seals the joint but rather the compression of the ferrule between the nut and pipe.
Why does my compression fitting keep leaking?
Compression joints are most common on shutoff valves, although you find them on other fittings as well.
Also make sure the pipe or tube goes straight into the fitting.
Misalignment will cause a leak.
If the fitting leaks after you turn on the water, try tightening the nut an additional one-quarter turn.
Can compression olives be reused?
Olives can’t be removed from a pipe and reused. Even hand tightening a fitting with an olive inside before the pipe is inserted, is enough to make the olive unusable. You can usually dismantle and remake a sound compression joints without ill effect.
Are Compression Fittings reliable?
Although compression fittings are generally considered more reliable than threaded fittings, there are some potential problems. In general, compression fittings are not as resistant to vibration as soldered or welded fittings. Repeated bending may cause the ferrule to lose its grip on the tube.
How do you reuse compression fittings?
4 Answers. If it hasn’t been tightened many times, it should be okay to reuse. Clean off the mating faces thoroughly and don’t use tape, putty, or anything else. And don’t be gentle tightening: The seal is formed by forcing the surfaces together and “bending” them to mate.
Are Compression Fittings safe for plumbing?
Compression fittings are a safe alternative for nonprofessional plumbers with limited confidence to make sweat connections. Since compression fittings don’t require heat, they can be used in tight quarters.
Can I over tighten a compression fitting?
Compression fittings work well if the pipe is clean and cut properly. Its often said in the trade to not over tighten a compression fitting, leaving you more thread in the case of a leak and not distorting the olive or fitting. Generally a nut will need one whole turn after hand tightening.
Does Teflon tape stop leaks?
Teflon tape will help prevent plumbing leaks. Its physical composition allows it to fill pipe threads and fitting threads with a sealant that will prevent water from leaking through the thread connection.
Can too much Teflon tape cause leaks?
If its still leaking from the teflon at the threads either try to turn the valve in some more.
You will need to hold that compression piece back with a channel locks while turning the valve in more.
If not take it out clean it and use more tape 5 turns .
Or less tape 2-3 turns and use teflon paste on the tape.
