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
- Push-to-connect interface
- Multi-direction outlet configuration
