Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice 44 Pneumatic fittings Technopolymer push-in fittings Series TECNORAP - TECNORAP BLACK FLUIDS Compressed air (for different fluid please contact our Technical Dept.) APPLICATIONS Pneumatic circuits, low pressure hydraulic applications, according to DIN 3861-3870 norms. Suitable for vacuum applications. SUGGESTED TUBES TPU (Polyurethane), PA11/PA12 (Polyurethane), TPE (Polyurethane), TPA (Polyurethane/Copolyester) TUBES TOLERANCES Diam. between 4 and 10 mm +/- 0,05 Diam. from 12 mm +/- 0,1 PROTECTION DEGREE IP 68 TEMPERATURE AND PRESSURE Recommended limit values Temperatures and pressures usually depend by the technical features of the employed tubes, anyway it is suggested a limit working pressure of 12 bar and a temperature range between -20°C and +50°C Technical testing data In the table below there are indicated the load traction resistance values and the main working and breaking limit (Pressure and Temperature) of the main commercial tubing. Note For more complete informations please read the technical catalogue of your tube supplier. THREAD TYPE BSP paralell UNI-ISO 228; BSP tapered UNI-ISO 7; Metric ISO/R 262 MATERIALS Body, sleeve, collar and back ring POM copolymer ISO1043-1; Technopolymer glass-fiber reinforced Swivel stems and bases Brass UNI EN 12164 CW614N Spring Stainless steel AISI 301 austenitic Seals NBR 70 DWGV-EN549 UL157 Technical sheet Additional technical informations Each Tecno-RAP production batch is tested according to severe cyclics “lot breaker” controls along all the production period, which include shape observation, leakage verification, functionality, at the working pressure of 8 bar. Then all samples taken from the lot are tested by a traction machine which simulate a breaking pressure of 50 bar. Here below are indicated the traction loads (in Newton) for each size: TUBE DIAMETER Ø4 Ø6 Ø8 Ø10 Ø12 BREAKING LOAD 63 N 141 N 251 N 393 N 566 N Important note: The values refer to the resistance of the crimping gripper, “core part” of both fittings, the technopolymer Tecno-RAP and the brass RAP, whereby homogeneous. The breaking experimental values measured, according to the diameter, were from 1.2 to 2.5 times higher. Additional information regarding the working temperatures: Further to all the necessary assessments on the use of the fittings in operating conditions different from how suggested in the initial technical sheet must be considered, with reference to temperatures, the nominal data regarding the type of the used tube and the limit imposed by the most critical component.
