## Product Summary

PC pneumatic fittings are male thread straight push-to-connect connectors designed for direct tube-to-thread connection in pneumatic systems.

With a straight-through structure and external threaded port, PC fittings allow pneumatic tubing to connect directly to equipment such as valves, cylinders, and manifolds without changing airflow direction.

Push-to-connect technology enables fast and tool-free tube installation while ensuring secure grip and leak-free sealing through an internal collet and sealing ring system.

Nickel-plated brass construction provides excellent corrosion resistance, wear resistance, and long-term durability in industrial environments.

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