CAST S.p.A.

THE NEW CAST 60° FITTINGS AN EASY ASSEMBLY A KNOWN PRODUCT, SAFE AND RELIABLE AVAILABLE IN CARBON AND STAINLESS STEEL THEORY OF OPERATION The CAST S.p.A. fitting according to the norms BSI 5200, is a mechanical fitting adapter traditionally used for high pressure oleo-dynamic systems. The sealing is made by the contact between two metal surfaces, with no deformation of the single components, plus an elastomeric sealing placed into a groove on the 60° cone. The elastomeric seal is according to a CAST S.p.A. project. The coupling between the body of the fitting and the adapter is guaranteed by the swivel tightening nut. This allow to realize a fast assembling-disassembling tube making the easiest realization of complex oleo-dynamic systems.

STANDARD DOUBLE CUTTING EDGE RING ASSEMBLED ON ALL CAST PRODUCTION ASSURES SEALING AND SAFETY. AVAILABLE IN CARBON AND STAINLESS STEEL THEORY OF OPERATION The Cast fitting, manufactured according to ISO 8434-1/DIN 2353 norm is a mechanical fitting with a double cutting ring for double stapling on the tube. The ring helps fast assembly of removable tubes, avoids welding, tapping and flaring, thus assuring maximum simplicity of complex oleo-dynamic systems. During tightening by the nut, the ring deforms according to the bore of the 24° cone of the fitting and bites into the steel tube, producing two deep cuts the first of which is visible due to lifting of an outer edge on the diameter of the tube, allows the water tightness and anti-unthreading of the ring. The second groove (invisible) balances the forces on the whole ring, prevents vibrations to reach the first groove and stops the stapling of the tube at a predetermined value.
