Can brass compression fittings be used on plastic tubing?

Can brass compression fittings be used on plastic tubing?

When using compression fittings with any type of plastic tubing, a brass insert must be used for further support. Compression fittings come in a variety of sizes and part numbers. No matter the application required, there is most likely a compression fitting that will work perfectly.

Can you use a compression fitting on vinyl tubing?

The use of softer tubing (such as polyurethane or vinyl) is not normally recommended with compression style fittings because the tubing wall is likely to collapse, or move away from the ferrule.

Can I use brass ferrule on plastic tubing?

Brass ferrules are normally used on copper tubing and can cut into the soft plastic supply line.

Can I use a metal ferrule on a plastic tubing?

Push the end of the plastic tube into the female compression fitting. Make sure the end of the tube slides “home” into the orifice. Push the compression nut onto the male threads of the female fitting. As you tighten the nut, the brass ferrule will crimp around the plastic tube and seal.

Can you use metal compression fittings with plastic pipe?

2 Answers from MyBuilder Plumbers 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 need Teflon tape?

The bolts have to be tightened evenly. 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.

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.

How do you attach brass ferrule to plastic tubing?

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. Push the end of the plastic tube into the female compression fitting.

Can you use a compression fitting on PVC?

If you’re dealing with underground metal pipes, you would clearly want to use metal plumbing compression fittings. Conversely, if you have plastic or PVC pipes, using a fitting of a similar material ensures that you don’t break anything along the compression plumbing fittings install.

Are brass 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.

Should I use plastic or brass sleeves for compression fittings on vinyl?

But on the vinyl side everything I see indicates that I should use a plastic sleeve on the outside of the tube inside the compression nut. In this case, however, the fitting that I picked up has captured brass sleeves (by which I mean that they’re attached to the nut, not a separate piece).

Can you use plastic tubing for compression fittings?

However, it really depends on the outside diameter and the inside diameter of the plastic tubing. When using plastic tubing, the “plastic sleeve” must be used and the “brass insert” must be used. The plastic sleeve is used to seal against the outside of the plastic tubing and the tapered end will seal into the compression fitting.

How do you use compression sleeves on copper tubing?

Use these sleeves with compression nuts and fittings to create a strong seal on stainless steel tubing. When used with high-pressure compression fittings and nuts, these sleeves bite into stainless steel tubing to form a strong seal. Use these sleeves with compression nuts and fittings to create a strong seal on copper tubing.

What is the brass insert used for in compression fittings?

The brass insert is used to keep the inside of the plastic tubing from collapsing as the compression fitting is tightened. The size of the plastic sleeve and the brass insert must be chosen according to the outside diameter dimension of the plastic tubing to be used.
