Product Function
PKB-G fittings enable multi-direction air distribution from a single threaded inlet, simplifying pneumatic system design and reducing installation complexity.
The integrated O-ring ensures a tight seal at the threaded interface, while the push-to-connect structure allows fast tubing connection without tools.
Compared to standard fittings:
- PKB-G = 5-way distribution + threaded connection + O-ring sealing
- Tee fitting = 3-way distribution only
- Cross fitting = 4-way distribution only
Product Structure & Size Range
- Models: PKB-G4 / PKB-G6 / PKB-G8 / PKB-G10 / PKB-G12
- Tube sizes: 4mm → 16mm
- Thread sizes: G1/8 / G1/4 / G3/8 / G1/2
