REPAIR COUPLER FOR P.E. TUBE
Screw-in menders are the best way to repair damaged P. E. tube in the field. These metal menders will
allow you to repair damaged tube without replacing the entire length of tube. These tube menders can be
obtained from your Micro Rain dealer.
INSTALLATION
1. Cut the tube with a hack-saw on either side of the damaged area. Make sure your cuts are straight.
Place expansion collar over each end of tube ( fig 1 ).
FIG 1
2. Chamfer/bevel the inside and outside of the tube with a knife or file, so that the threads of the metal
mender will enter the tube.
3.
NOTE!!
The threads on the metal mender are lefthand threads on one end and righthand threads
on the other. Screw the mender in one end about 2/3 of the way using a wrench. Then unscrew it.
Repeat the procedure on the other end. Remember one end is left-hand thread. Do not apply heat to
the tube during this procedure ( fig 2 ).

4. Complete the procedure by starting the threads in both ends at the same time, turning the mender
with a wrench. Screw the mender all the way into the tube until the two ends meet and are snug
(fig 3).
