Can you use compression fittings on plastic?

Plastic can be attached to compression fittings without problems. Just make sure you put an insert into the end of the plastic pipe to strengthen it and then tighten the fitting as normal.

Do compression fittings last?

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 tight should a plastic compression fitting be?

Form a Snug Connection Between Pipe and Fitting Before Tightening. Insert the pipe and work it in until only about 1/8 inch of the pipe shows beyond the compression ring. Then you can tighten to the correct tension without worrying about cracking the pipe or tube.

Can you use a compression fitting on PEX?

Compression fittings for PEX operate in much the same way as compression fittings for copper or other plastic piping. Making the connection involves placing the compression insert inside the end of the PEX tubing, sliding the compression ring over the tubing, then securing it with the compression nut.

Can you use brass olives on plastic pipe?

Olives are available to fit the joining pipe in a variety of sizes from 8mm to 54mm. Olives are ideally suitable for use with compression joints and copper or plastic pipe. When compressed the olive forms an air and watertight seal that will hold the pipe securely within the grip of the joint.

What’s better compression fittings VS soldering?

Compared to soldering, press fitting is faster and requires less training. However, traditional fittings for soldering are lower cost, time tested and reliable when professionally installed.

Is a compression fitting as good as solder?

Compression fittings are not nearly as robust as soldered fittings making them much more sensitive to powerful stresses. They are not ideal for applications where they could be potentially exposed to lots of flexing, bending and excessive vibration or tube movement.

Do compression fittings work on PEX?

How do you install ferrule on plastic tubing?

Slide the brass compression nut over the tubing approximately 2 to 3 inches from the cut end. Grab the brass ferrule between your index finger and thumb and work the ferrule over the plastic tube. The fit will be a little tight, but this is what you want. Work the ferrule approximately 3/4 inch from the cut end.
