What are Compression or Flareless Tube Fittings?

Compression Tube fittings or Flareless Compression Fittings are a type of pipe fitting used in plumbing and mechanical systems. These fittings can be used to connect copper pipes, PVC or steel pipes. In addition, they can also be used for compression joints or couplings to join two lengths of pipe together.

A compression tube fitting is a pipe joint that uses a screw thread to compress the two ends together. Compression tube fittings are used in low-pressure applications. They are commonly used in refrigeration, air conditioning, and plumbing systems because they can be easily disassembled.

Unlike other types of joints, compression tube fittings do not need additional sealing materials like gaskets or O-rings because they seal from the threads alone. Compression Tube Fittings also don't require special tools or equipment for installation. These types of pipes can be installed using a crescent wrench, which is useful if you're working in a tight space where other wrenches won’t fit.

Compression tube fittings consist of two main components: the coupling nut and the compression ring. The nut is threaded onto a pipe or tube to be joined together with another pipe or tube at the desired angle, which is then tightened by hand. The compression ring is placed over the end of one pipe that has been inserted into the other end. It's tightened until it reaches its maximum capacity without being able to tighten any further.

At DHH, Flareless Compression Tube Fittings come in either Steel, Brass, or Stainless Steel depending on your use or application.
