## Product Summary

PKB-G pneumatic fittings are 5-way push-to-connect connectors designed for multi-direction air distribution and tube connection in pneumatic systems.

With a cross (five-port) structure, PKB-G fittings enable one air source to be distributed into multiple directions, making them ideal for compact pneumatic layouts and centralized air routing.

The fitting is manufactured using nickel-plated brass combined with an O-ring sealing system, providing corrosion resistance, stable sealing, and long-term durability.

Push-to-connect technology allows quick installation and removal without tools, improving efficiency in complex pneumatic piping systems.

OEM and ODM customization services are available for tube size, port configuration, and branding requirements.
