Polyethylene Tube Repair
Tube menders can be purchase from your Kifco Dealer
Warning!
Installing fittings or repairing polyethylene tube used on your Water
-
Reel is hazardous! The tube
has a memory from being coiled on a reel and will try to coil back up if the tube is loosened from one end
or cut in two. The condition possesses a serious hazard to person and/or property. The tube must be re-
strained any time there is a loose end!
Polyethylene Tube Repair
Screw
-
in menders are an excellent alternative to butt
-
fusion welding for the repair of polyethylene tube. The com-
pact design allows a mender to be wound onto the spool without damaging itself or the adjacent coils of tube. They
can be installed in the field and the tube can be put into service immediately after the repair is made. The menders
are designed to be fitted at ambient temperature. Never try to apply heat to assist installation. Menders must be in-
stalled straight and concentric with the tube to prevent premature failure.
Cut the tube on either side of the damaged
area. Make good, straight cuts. Use a block of
wood or soft hammer to tap the collar fully on
to the end of the tube.
Chamfer the tube internally with a knife or
coarse file so that the end of the screw
-
in
mender will enter the tube.
Important: Please note the mender threads
are different on each end. One is left hand and
one is right hand. Screw the mender about
2/3rds into the end of the tube using a wrench
on the center knurled shoulder. Then unscrew
it. Repeat the procedure for the other end.
Watch for the left hand thread.
Now start the mender in both ends simultane-
ously. As it screws in, it will draw both ends of
the tube to the center. This time, screw it all
the way to the shoulder. The tube should now
be ready to go immediately back into service.
