Central body
Carbon steel central body conveniently built in order to allow a perfect insertion of the gasket inside its dedicated conical seat.

Compression ring
Carbon steel compression followers which allow compression of the gasket onto the pipe surface upon tightening the bolts.

Gasket
Truncated-cone sealing gasket which can be perfectly inserted between the central body of the coupling and the circumference of the pipe. It allows a complete hydraulic seal and a 30 mm tolerance range on the pipe OD.

Bolt holes
Round or square holes for the bolt insertion.

Compression bolts
The compression bolts allow the approaching of the compression flanges and the consequent compression of the gasket onto the pipe.

Radial set of pull-out resistance grippers
Manufactured in C40 tempered steel, they allow the total locking of the pipe. End restraint grippers, which can be used on PE, steel, DCI and PVC pipe lines, guarantee a pull-out resistance action and their special design allows an easy assembly and disassembly of the coupling without damaging the Rilsan coating.

End restraint containing ring
Manufactured in carbon steel, optimizes the pull-out resistance action, also avoiding the rotation of the grippers during the tightening phase.

Connection flange(Flanged version)
Carbon steel flange.

Separate bolts version
The bolts tightening is independent in order to improve the coupling centering and the performances of the gasket.
