COMPRESSION FITTINGS ASSEMBLY INSTRUCTIONS
PIPE PREPARATION & CAP UNSCREW:
Cut the pipe round and square and remove the burrs; better to chamfer greater than 75mm. Unscrew the Cap to the last thread, leave it on the fitting while inserting the pipe.
PIPE INSERTION UP TO THE FIRST PIPE STOP:
Twist the pipe into the fitting through the grip ring till the first stop: the pipe has reached the O Ring. Pipe insertion up to the first pipe stop. Balance sealing system. The O Ring has two. opposite lips that allow easier pipe insertion. The right placement of the O Ring in the body round to avoid twisting. The better adaptability of the Ring towards the body and the pipe wall. (large contact pipe surface)
PIPE INSERTION UP TO THE BODY PIPE STOP:
Push the pipe through the gasket till the second stop, you have reached the pipe stop ribs of the fitting. Balancing of O Ring
The radial body site and the conical gasket are designed to keep the gasket lightly up in the site: after the pipe insertion it doesn’t reach directly the body pipe stop, it also remains a little raised from the pipe stop thanks to the internal ribs in the body.
SCREWING THE CAP:
Tighten the Cap firmly by hand or standard tool up to 20-32mm, and by standard Pipe wrench for greater than 40mm; the pipe moves to the very final body stop.
Balancing of O Ring:
By tightening the Cap it works on the thrust ring that push the O Ring, meanwhile the pipe is moving to the final stop in the body: the O Ring can deeply place in its site also moving radially and increasing its compression towards the pipe wall, as much as it’s possible in relation to the dimensional. In this way, acting on the tightening level of the Cap, it is possible to realize a system able to balance pipe defects such as undersize and ovality in standard
