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.

Connection flange (Flanged version)
Carbon steel flange.

  • The data concerning the min. and max. gap is calculated on the minimum outside diameter of the product's range
  • This chart is for indicative purposes. Nova Siria srl can vary the indicated standards (tolerance range, dimensions and materials) according to specifications requested by Customers or to designing needs.
  • Multisize series and wide range steel fittings provide the maximum hydraulic seal, however they do not restrain axial pipes movement (for this type of products please refer to the MULTIGRIP section)
