Step-by-Step Installation Guide – Union Rubber Flexible Joints

1. Preparation:
   • Ensure pipe ends are clean, free from burrs, rust, or debris.
   • Check that union threads are compatible with system piping.
2. Alignment:
   • Align piping to minimize stress before installing the joint.
   • Do not stretch, compress, or twist the joint beyond its design limits.
3. Connection:
   • Hand-tighten the union joint into position.
   • Use a wrench for final tightening but avoid over-torque to prevent thread damage.
4. System Testing:
   • Gradually pressurize the system.
   • Check for leaks at union connections.
5. Maintenance:
   • Inspect periodically for cracks, bulging, or deterioration.
   • Replace if signs of fatigue or chemical attack are visible.
