Compression fittings S16

Product documentations


S 16 compression fittings for pressure piping applications are characterized by the Innovative Balance Sealing System Posei- don (pat pending): thanks to the new technical design it is possible to balance the sealing action towards the pipe through thedifferent tighteningofthenut.Thisleadstothemaximumsafetyinallthepossibleconditionsofuseandqualityofthe pipe , keeping the basic features of easy and fast assembly without any particular preparation of the pipe.

Product range: d.16-110mm,all the common items for piping applications.

: top quality raw materials are used, this makes the S 16 fittings highly resistant and reliable in time, suitable for drin- king water and environment compatible.
