## Product Summary

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

With a central body and five connection ports, PKB fittings allow multiple tubes to be connected from a single point, making them ideal for compact air distribution, branching circuits, and manifold-style layouts.

The push-to-connect structure enables fast installation and secure tube connection without tools, improving efficiency in pneumatic assembly and maintenance.

The fitting features a durable metal body combined with engineering plastic components and sealing elements, ensuring corrosion resistance, stable sealing, and long service life in industrial environments.

OEM and ODM customization services are available for tube size, thread type, and branding requirements.

### Key Features

- 5-way multi-port design for air distribution

- Centralized connection for multiple tubing lines

- Push-to-connect quick installation

- Compact structure for space-saving layouts

- Durable metal body with plastic components

- O-ring sealing for reliable leak prevention

### Applications

Pneumatic distribution systemsUsed for splitting air flow into multiple directions from one source

Industrial automation systemsSupports multi-line connections in compact equipment

Air manifold and branching circuitsSimplifies piping layout and reduces connector count

Machinery equipmentIdeal for multi-output air routing

Control systemsProvides centralized air distribution point

### Product Function

PKB fittings are designed to distribute compressed air from a single input to multiple output lines.

They function as a **multi-port distribution connector**, reducing the need for multiple tees or connectors and simplifying pneumatic system design.

Compared to standard tee or cross fittings:

- Tee (3-way) → limited branching

- Cross (4-way) → fixed layout

- **PKB (5-way) → more flexible multi-direction distribution**

### Product Structure & Size Range

- Models: PKB4 / PKB6 / PKB8 / PKB10 / PKB12 / PKB16

- Tube sizes: 4mm → 16mm

- Thread sizes: M5 / R1/8 / R1/4 / R3/8 / R1/2

- 5-port central structure
