how to use


The ½ in. compression PVC Insert is used in the installation of a drip irrigation system to connect ½ in. drip tubing with .700 OD to .704 OD to a PVC pipe.


To connect the drip tubing into the compression fitting, first, glue the insert into a ½ in. PVC slip coupling, elbow, or tee and let it dry for an hour. Insert the ½ in. drip tubing end with .700 to .704 OD into the compression side of the insert, pushing and wiggling the drip tubing back and forth into the fitting. The 1/2" compression fitting side uses a simple wrist action and the drip tubing is "walked" into the fittings for a very tight fit, ensuring watertight connection.
