Product Overview

Straight Repair Joiners are used for repairing Underfloor heating pipes. Commonly known as a straight coupler. Sold complete with 16mm Nuts, Olives and Inserts and Nipple. Easy to use and install. We highly recommend pressure testing before covering. Please ensure the pipe is cut straight and not at an angle as this can cause leaks.

How to use:

  1. Cut both sides of the damaged section of pipe.
  2. Slide the nut onto the pipe
  3. Slide the olives onto the pipe.
  4. Push the inserts into the pipe.
  5. Tighten the compression nut onto the 3/4″ Straight Nipple with a spanner.
