Introduction to Compression Fittings and Plastic Pipes
Compression fittings are widely used to connect pipes securely without welding. Plastic pipes, such as PVC, PEX, and polyethylene, are common in plumbing systems. Combining the two requires understanding their compatibility. This article explores whether you can put a compression fitting on plastic pipes.
Understanding Compression Fittings
A compression fitting consists of a nut, a compression ring, and a fitting body. It creates a tight seal by compressing the ring onto the pipe. These fittings are commonly used with metal or rigid plastic pipes. Their adaptability makes them a popular choice for various applications.
Types of Plastic Pipes
Plastic pipes include PVC (polyvinyl chloride), PEX (cross-linked polyethylene), and polyethylene. Each type has unique properties, such as flexibility, durability, and resistance to chemicals. Understanding these properties helps determine compatibility with compression fittings.
Compatibility of Compression Fittings with Plastic Pipes
You can put a compression fitting on plastic pipes, but with caution. Plastic pipes may deform under pressure if not supported properly. Specialized compression fittings designed for plastic pipes are recommended. These fittings ensure a secure and leak-free connection.
Types of Compression Fittings for Plastic Pipes
Specific compression fittings are designed for use with plastic pipes. These fittings often include a support sleeve or insert to prevent deformation. Examples include John Guest fittings and SharkBite connectors. Choosing the right type ensures compatibility and reliability.
Installation Tips for Compression Fittings on Plastic Pipes
Cut the pipe squarely and ensure it is clean and free of debris. Insert the pipe fully into the compression fitting and tighten the nut securely. Avoid over-tightening, as it may damage the pipe. Following manufacturer guidelines ensures a proper and durable connection.

Advantages of Using Compression Fittings on Plastic Pipes
A compression fitting offers ease of installation and does not require specialized tools. It provides a quick and reliable connection for plastic pipes. These fittings are also reusable, making them cost-effective for temporary or adjustable systems.
Conclusion
You can put a compression fitting on plastic pipes with the right precautions. Specialized fittings designed for plastic ensure a secure and leak-free connection. Proper installation techniques and tools are essential for success. Compression fittings.
