What are PP Compression Fittings and what are they used for?

Oct 15, 2026

Definition and material composition
PP Compression Fittings are mechanical connectors made from polypropylene. They join pipes without heat or glue. A nut compresses a ferrule against the pipe. Example: a plumber joining two PP pipes.

Key components
A PP Compression Fitting has three main parts. The body, the nut, and the ferrule. The ferrule is compressed onto the pipe. Example: a fitting with a brass ferrule.

How they work
The pipe is inserted into the fitting body. The nut is tightened with a wrench. This compresses the ferrule onto the pipe. PP Compression Fittings create a watertight seal.

Common types
PP Compression Fittings come in many shapes. Elbows change direction. Tees create branches. Couplings join pipes. Reducers connect different sizes.

Residential plumbing
PP Compression Fittings are used in residential plumbing. They carry hot and cold water. They are easy to install. Example: a home water supply system.

Commercial plumbing
PP Compression Fittings are used in commercial buildings. They are used in hotels and schools. They handle large water volumes. Example: a hotel's water system.

Irrigation systems
PP Compression Fittings are used in irrigation. They connect pipes in the field. They resist soil chemicals. Example: a farm irrigation network.
