| Body | The main part of the fitting that connects to the pipe. |
| Compression Ring | A ring that compresses around the pipe to create a tight seal. |
| Nut | A threaded component that tightens to compress the ring against the pipe and fitting body. |
When the nut is tightened, it compresses the ring around the pipe, forming a leak-proof seal. This mechanism allows for easy assembly and disassembly, making maintenance and repairs more manageable.
Types of Connections
PP compression fittings provide various connection types that enhance installation and performance. These fittings are known for:
- Durability and corrosion resistance, which improves their performance in diverse applications.
- Leak-free connections, essential for maintaining system integrity.
- Simplified installation, allowing for faster and easier setups compared to traditional methods.
The fittings consist of a compression nut, an O-ring, and a compression body. Together, these components ensure a reliable connection that accommodates pipe movement, making them ideal for dynamic environments.
Pressure Handling Capabilities
PP compression fittings are designed to withstand significant pressure, making them suitable for demanding applications. Key points regarding their pressure handling capabilities include:
- Pressure ratings indicate the maximum pressure that these fittings can endure, ensuring safety and reliability.
- These ratings are typically expressed in pounds per square inch (psi) and can vary based on temperature and application.
- PP compression fittings are engineered to have high-pressure ratings, suitable for various environments.
This ability to handle pressure effectively makes PP compression fittings a preferred choice for both residential and commercial plumbing systems.
