    Installation Steps

    1. 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
    2. 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
    3. Installation Check

      • Gently pull each end of the tubes to confirm secure connections
      • Check for air leakage at each connection point
      • Ensure the entire connection system is secure and reliable

    Troubleshooting

    • Tube cannot be inserted: Check if the tube is damaged or deformed; confirm the tube size matches the connector
    • Air leakage at connection: Verify that the tube is fully inserted; check if the O-ring seal is intact
    • Insufficient flow: Check for tube blockage; confirm if the connector size is suitable for system requirements
