Compression fittings
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:
- Brass
- Plastic
- Copper
- 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.
Types of compression joints: There are two basic types of compression:
- Type A or non-tampered fittings: These fittings are easy to install and do not require a change in the pipe. Type A compression fittings are also known as olives and can be installed using an ordinary wrench to tighten the nut around it. These connections are commonly used for water connections.
- Type-B or manipulative fittings: Installing Type-B fittings requires flare or pipe blows. In order to remove this type of connection, special traction tools are often used to sidewall the nuts and olives around the pipe or tube. Type B fittings are mostly used for gas lines.
Shopping Tips
The factors to consider are:
- The materials used in the manufacture of compression fittings are very important for the proper connection of pipes and fittings.
- The size of the connections is also important and the right size must be chosen for proper use.
Common cases:
Compression fittings are used globally for piping applications are used to connect thin-walled pipes or two pipes to each other. These fittings are widely used for hot and cold water taps. And toilet stop valves
Instructions for using compression fittings:
- Compression fittings Always use permanent or fixed compression fittings. These fittings are designed to restrict the movement of the pipe away from the fittings.
- When installing the compression fittings, care must be taken not to tighten them too much. Special care should be taken when using plastic pipes. Because there is a point that tightening a compression nut will no longer be of any use.
- When plastic pipes are connected by compression fittings, a plastic compression ring should always be used instead of a metal ring.
- Compression fittings Do not use pipes or curved pipes.
