- Straight-through structure for straight line pipe connections
- Both ends can connect PU tubes, no tools required for installation
- Available in multiple sizes (4mm, 6mm, 8mm, 10mm, 12mm)
- Suitable for compressed air systems

Installation Steps
-
Preparation
- Confirm that the PU Series Union Straight size matches the tube size
- Prepare the required size of PU tubes
- Ensure the work area is clean and free of debris
-
Installation Process
- Cut the ends of the PU tubes straight, ensuring perpendicular cuts
- Push one tube into one end of the union; a "click" sound indicates proper installation
- Push the other tube into the opposite end of the union; a "click" sound indicates proper installation
- To disassemble, press the release sleeve and pull out the tube
-
Installation Check
- Gently pull each end of the tubes to confirm secure connections
