## Product Summary

PKB pneumatic fittings are **5-way male thread push-to-connect connectors** designed for multi-direction air distribution in pneumatic systems.

With a five-way structure, this fitting allows multiple tube connections from a single threaded port, making it ideal for compact air distribution, branch circuits, and complex pneumatic layouts.

The one-touch push-in design enables fast installation without tools, while the nickel-plated brass body ensures strong sealing performance and corrosion resistance.

PKB fittings support PU tube and nylon tube, with working pressure up to **0–0.9 MPa** and proof pressure up to **1.32 MPa**, suitable for industrial pneumatic applications.

**OEM and ODM customization services are available** for tube size, thread type, sealing materials, and branding.
