--Maintenance & Adjustment--
4. Now place the sleeve on the tube and push it on until it is flush with the cut end
of the tube.
5. Apply lubricant to the fitting and to the inside of the tube. The best lubricant is
liquid dishwasher soap. Now screw the fitting in until all the threads are in the
tube. Again, take care to keep the fitting straight.
6. Reach inside the coupling and remove any shreds of polyethylene created as a
result of cutting the thread in the tube. These may foul the sprinkler.
Tools used during installation depend on which fitting is being installed. To install a flange-
style fitting, use bar 5 or 6 feet long placed between two bolts inserted through the holes in
the flange. For the spool elbow, use a pipe and/or a large pipe wrench. For fittings with
drive lugs inside the fitting, a special installation tool is required. This tool is not provided
with the fittings.
Fittings that Require a Driver
The following diagram shows a typical driver for these fittings. The blade of the driver is
made from 3/8” x 4” plate. The width of the blade is the same or slightly less than the
diameter of the fitting. Weld the blade to a heavy steel bar or 1” schedule 80 water pipe
approximately 48” long.
