Join Lead Pipe to Copper Pipe

Website use is conditional on agreeing with the Disclaimer

Need to join an old lead pipe to a copper pipe then you need a Lead-Loc


This is a compression joint for lead pipes that make a good reliable joint. This is not a new solution as they have been around for years.

I won't go into the fitting of these as there are plenty of Youtube videos on this subject.

You can buy a variety of sizes to match your lead pipe.

If you need to connect a lead pipe to plastic pipe then a fitting for this is also available - Lead-Loc Plus

Lead-Loc Installation Guide

  1. Cut the lead pipe.
  2. Smooth it’s surface for about 50mm from the end.
  3. Removing the minimum of lead and chamfer the end.
  4. The ideal lead pipe size is shown underneath the coupling description overleaf (on header card).
  5. It should be a free fit without excessive play.
  6. Re-assemble the coupling.
  8. TechTip: To determine the outside diameter of the pipe, wind a length of cotton twice around the pipe without stretching it and then measure its length.
  9. Divide this result by 44 and multiply this answer by 7.
  10. This is then the diameter of the pipe.
  11. Insert the lead pipe into the coupling body until it reaches the internal stop.
  12. Hold the body with a suitable wrench and tighten the lead thrust nut fully.
  13. Maximum torque necessary is 15lbf.ft.
  14. The 15mm or 22mm copper tube end is a conventional compression fitting.
  15. A seal should be achieved after one turn maximum or 10lbf.ft torque.
  16. Do not overtighten as this could damage the nut.
  17. Pressure test when complete and re-tighten coupling nuts.
  18. The Gripper Ring (Number 3 In Diagram) has necessary sharp edges, TAKE CARE WHEN HANDLING THIS COMPONENT.
