Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice 14 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 (Polyamide), TPE (Polyethilene), TPA (Polyurethane/Copolyester) TUBES TOLERANCES Diam. between 4 and 10 mm +/- 0,05 Diam. from 12 mm +/- 0,1 PROTECTION RATING 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 15 bar and a temperature range between -20°C and +70°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, “OT” sleeve, stems and swivel bases Brass UNI EN 12164 CW614N Sleeve, collar and back ring POM copolymer ISO1043-1 Spring Stainless steel AISI 301 austenitic Seals NBR 70 DWGV-EN549 UL157 Technical sheet Pneumatic fittings Push-in fittings Additional technical informations Each 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 Ø14 BREAKING LOAD 63 N 141 N 251 N 393 N 566 N 750 N Important note: The values refer to the resistance of the crimping gripper, “core part” of both fittings, the brass RAP and the technopolymer Tecno-RAP, whereby homogeneous. The breaking experimental values measured, according to the diameter, were from 1.2 to 2.5 times higher. Brass push-in fittings Series RAP - RAP BLACK - OT 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.
