## Product Summary

PB pneumatic fittings are **male thread branch tee connectors** designed for efficient air distribution and branching in pneumatic systems.

With a **T-shaped structure**, the PB fitting connects two tubing lines with one male threaded port, allowing air to be distributed in multiple directions within compact system layouts.

The push-to-connect design enables fast installation without tools, ensuring secure and leak-free connections. Quick-connect fittings work by locking the tube with internal teeth and sealing with an O-ring for airtight performance.

PB fittings are widely used with **PU tubing and nylon tubing**, supporting reliable operation in industrial automation and compressed air systems.

**OEM and ODM customization services are available** for thread types, tube sizes, sealing materials, and branding requirements.
