## Product Summary

PGJ pneumatic fittings are **plug-in reducer push-to-connect connectors** designed for connecting different tube sizes in pneumatic systems using a stem (insert) structure.

With a **push-in port on one side and a plug-in stem on the other**, PGJ fittings allow direct size reduction between tubing or fittings, making them ideal for compact and flexible pneumatic layouts.

This design simplifies installation and reduces the number of fittings required in the system.

Push-to-connect technology enables fast installation and secure sealing without tools, improving efficiency and reliability.

**OEM and ODM customization services are available** for tube size combinations, materials, and branding requirements.
