THEORY OF OPERATION The Cast fitting, manufactured according to BS 5200, is a mechanical adapter traditionally used for high pressure fluid-dynamic systems. The sealing is made between two conical surfaces, metal to metal, with no deformation of the components, plus an elastomeric sealing (0-Ring) placed into a groove on the 60° cone. N.B. The elastomeric seal is made according to a CAST S.p.A. project. The connection between the body of the adapter and the body of the component is guaranteed by the swivel tightening nut and the threaded parts for the other types. It helps fast assembly of...

TECHNICAL CHARACTERISTICS Cast 60° fittings assure perfect seal regardless of the fluid used, provided that no corrosive fluids be employed, the nominal pressures of the fittings and the indicated temperatures be respected and the prescriptions of the manufacturer be followed scrupulously. These fittings are manufactured in a single series defined “UNIVERSAL” and combine the various (regulatory) series of fittings: DIN 2353- SAE J514- SAE J1453- SAE J516 etc. Normal vibrations do not alter the functionality of this type of fitting, also at the top quoted values. Therefore the fitting...

PRODUCT CONCEPT • The idea has been to use the standard 60° adapter structure and place an O-ring in the 60° conical part to add an elastomeric seal to the traditional metal to metal seal. • The new adapter with elastomeric seal solves the problem of small leakages, leaks and sweating that are typical of a metal to metal sealing system on high pressure fittings. • The introduction of the new adapter with elastomeric seal in any case does not limit the required performance for adapters with or without elastomeric seal. SEALING The new adapter solves the total sealing problem in the following...

TIGHTENING TORQUES ON THE SWIVEL CONE BS 5200 cone for carbon and stainless steel Notes: The values in the tightening tables are approximate and derive from practical tests run at the laboratory in Casalgrasso (CN), which may vary based on the materials and tolerances of the components used. Thus an awareness of the controls to be performed is required. All the values expressed in Newton Meters (Nm) for the tightening torques on the BS 5200 swivel cone represent the torquing moment needed to obtain the correct tightness. SAFETY FACTORS The technical choice to use the wire, rather than the...
