Tapping Band Installation Instructions
- Clean pipe area where tapping band is to be installed. Ensure no dirt or pipe surface defects are present.
- Prior to installation inspect tapping band parts to ensure seals are clean and defect free.
- Position tapping band bottom-half under pipe and hold in place. O-Ring or Multi-Lip seal tapping bands – check correct seal position prior to fitting tapping band onto pipe. E-Lip seal tapping bands – check correct seal position prior to fitting tapping band onto pipe. Position lug into matching band groove notch to ensure correct alignment and avoid leaks.
- Fit tapping band top-half over pipe so bottom-half bolts pass through top-half bolt holes.
- Continue to hold bottom-half while fitting washers and nuts. Finger tighten nuts ensuring equal gaps between tapping band halves on both sides.
- Final position and level tapping band if required.
- Using a torque wrench, tighten nuts evenly in stages to 15Nm (10ft/lbs). Ensure even gaps on both sides if applicable. Re-torque after approximately 20 minutes.
- Apply no more than three (3) wraps thickness of AGA (gas) or WaterMark (Water) approved premium PTFE thread tape should be applied to the full length of male take-off fittings threaded into tapping bands.
- Maximum recommended installation torque for take-off fittings is 30Nm (20Ft lbs). Recommended installation when not using a torque wrench is hand-tight plus half to one-full turn. Ferrules must not be screwed in deeper than their thread depth.
- Take-off pipes must be oriented to avoid exerting undue leverage force on tapping bands.
- Take care not to damage band or force swarf under seal when tapping pipe through tapping band.
- A good practice after tapping is to permanently mark pipe so the band can be replaced exactly and centrally over a tapped hole if removed later for any reason.
