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.
Are compression fittings bad?
Compression fittings are to be used on stationary connections only… If you look critically at compression fittings, one thing is apparent… they are designed to inhibit the movement of the pipe outward from the fitting. However, they do a poor job preventing the pipe from turning within the fitting.
What are compression threads?
Compression fittings have straight threads and are made of brass or plastic and are often used on soft copper pipe and small-diameter tubing. The angle stop under your sink is one example of compression threads.
What is Type A compression fittings?
Type A compression fittings. Type A, or non-manipulative fittings enable the plumber to make a compression joint without carrying out any work on the tube ends other than ensuring that they are clean and cut squarely. Type A compression fittings can be used to join pipes above ground only.
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.
Can you over tighten compression fittings?
If the pipe is clean and cut properly, compression fittings work well. In the trade, it’s said to not over tighten a compression fitting, leaving you more thread in the case of a leak. After hand tightening a nut will need one whole turn.

What are ultra high purity compression fittings called?
Polished to a 15 Ra and under finish, these fittings have a mirror smooth interior. They are also known as ultra-high-purity fittings. A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal.
