Prodotto in ACCIAIO AL CARBONIO CARBON STEEL AND STAINLESS STEEL PRODUCT STANDARD DOUBLE CUTTING EDGE RING ASSEMBLED ON e in ACCIAIO INOssidabile ALL CAST PRODUCTION TO ASSURE SEALING AND SAFETY. AVAILABLE IN CARBON AND STAINLESS STEEL

THEORY OF OPERATION The Cast fitting, manufactured according to ISO 8434-1/DIN 2353, is a mechanical fitting with a double cutting edge ring for double stapling on the tube. The B3 ring helps fast assembly of removable tubes, avoids welding, tapping and flaring, thus assuring maximum simplicity for 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 the lifting of an outer edge on the diameter of the tube, ensuring water...

TECHNICAL CHARACTERISTICS CAST fittings assure perfect seal regardless of the fluid used, provided that no corrosive fluids are employed and the nominal pressures be respected. Fittings are manufactured in three ranges to be chosen according to the required working conditions. The “LL” extra light range, suitable for low and medium working pressures up to 100 bars. The “L” light duty series for applications characterised by medium high pressures of maximum 500 bars. The “S” heavy duty series for harsh applications characterised by high temperatures and a maximum pressure of 800 bars. Normal...

NEW SIX-SEALS CUTTING RING. THE INTERNATIONAL INDUSTRIAL PATENT NR. 864061 OF 10/03/99 COMPLEMENTS AND DOES NOT REPLACE THE STANDARD RING CURRENTLY IN USE. AVAILABLE IN CARBON AND STAINLESS STEEL

THEORY OF OPERATION The Cast fitting, manufactured according to ISO 8434-1/DIN 2353, is a mechanical fitting with a double cutting edge ring for double stapling on the tube. “B4” is a highly innovative, deformable, double clinching, double edge ring with double elastomer seal. It is assembled according to well-known techniques and is perfectly interchangeable with all types of rings used on 24° cone fittings complying with ISO 8434-1/DIN 2353 standards. The ring helps fast assembly of removable tubes, avoids welding, tapping and flaring, thus assuring maximum simplicity for complex...

TECHNICAL CHARACTERISTICS The “B4” ring assures perfect tightness of the circuit regardless of the fluid used, provided that corrosive fluids are avoided and the nominal pressures of the fittings are complied with. The fittings on which the “B4” rings are mounted are manufactured in two series, which are used according to the operating conditions. The “L” light duty series for applications characterised by medium high pressures of maximum 500 bars. The “S” heavy duty series for harsh applications characterised by high temperatures and a maximum pressure of 800 bars. Normal vibrations do not...

TECHNICAL INNOVATION For many years now there has been an increasing imperative market demand for fluid system components that guarantee three main factors: SAFETY, EASY ASSEMBLY, LEAKAGE-FREE TIGHTNESS. These elements, now considered essential for a safe working environment (Law 626/94), product liability (Presidential Decree 224-EEC 85/374) and for the entire environmental protection system, have promoted the development of the new “B4” ring as an effective response to all the above-mentioned problems. PRODUCT CONCEPT The most original aspect of the product is that the structure of the...

GENERAL INSTRUCTIONS FOR B3 - B4 - BP RINGS • Before starting the preassembly make sure that the pierce of the machine and the hardened blocks are in perfect working order. Further inspections are necessary during the preassembly (every 30-50 tightenings). For this purpose we recommend you to use a control buffer 1000… pierce and replace any block out of tolerance. • Over the whole tightening phase the tube must be in touch with the inner part of the body of the fitting. If this does not happen, the ring will advance with the tube without indenting it, making the coupling not functional and...
