Locking Band (Old Design): Verify the 
gasket is seated evenly inside the groove in 
the female end of the pipe.  For PP / Metal 
pipe with a locking tab, slide the Locking 
Band on to the male pipe section Fig.3a. 
Insert locking tab into locking band recess, 
rotate button away from locking band clasp, 
insert pipe sections, push lock band clasp 
downward over the socket, disengage tab 
1/4"-5/8" from socket. 
Locking Clamp (New Design): Verify the 
gasket is seated evenly inside the groove 
in the female end. Assemble the joint by 
passing the male end of the Polypro Pipe 
through the Locking Clamp on the hose 
clamp side and into the female end of the 
PolyPro pipe, (Fig.3b). Hook the Locking 
Clamp onto the gasket extrusion on the 
female end and tighten down on the hose 
clamp.
The new Locking Clamp design is 
backwards compatible with pipe sections 
designed for use with the Locking Band. 
Use pliers to break o the Locking Tab with 
a twisting motion. Once removed, install 
the pipe section following the Locking 
Clamp instructions. Locking Clamps can be 
purchased separately in packs of 12.
