Compression fittings are a special type of connection that is usually used to connect two pipes or one pipe to a fixture or valve. Tighten the sleeves or ferrules on the joints to prevent leaks. These pipe fittings are very strong and reliable and can only be used with a pair of wrenches. These connections do not require heating and work well even with wet pipes.
Compression fittings are ideal for home plumbing applications
Materials used Compression fittings
Compression fittings are usually made of materials such as:
- Cast Iron
In cases where compression fittings are used to connect pipes of two different materials, for example PVC and copper, such materials must be made that are suitable for the connection.
Parts of compression fittings:
Pipe compression fittings consist of three parts :
- Compression nut
- Compression ring or inner ring or “olive”, and
- Compression seat
How do compression fittings work?
As the name implies, the compression fittings apply compressive pressure to the pipe and tube fittings, thus forming a tight seal. In order to prevent liquid leakage, the fittings are pressed against the pipe with a force that eliminates any space between the fittings.
