Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice 82 Technical sheet Pneumatic fittings Push-in fittings FLUIDS Compressed air and main food fluids APPLICATIONS Compressed air applied to machines intended for the food and beverage field (boxing, bagging machines, vacuum packaging, oenology, etc.) and machines for the passage of low temperature drinkable fluids (filling, bottling, tapping, etc.) SUGGESTED TUBES TPU, PA11/PA12, TPE, TCO for compressed air. PE, PVC, PELD for food fluids. TUBES TOLERANCES Diam. between 4 and 10 mm +/- 0,05 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 parallel UNI-ISO 228; Metric ISO/R 262 MATERIALS Body and swivel bases Brass UNI EN CW510L Sleeve, collar and back ring POM copolymer ISO1043-1 (REG. UE 10/2011) Spring Stainless steel AISI 301 austenitic Seals NBR 70 DIN-ISO 1629 (DM 21:1973, FDA 177.2600) Additional technical informations Each FCM 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 BREAKING LOAD 63 N 141 N 251 N 393 N Important note: The values refer to the resistance of the crimping gripper, “core part” of both fittings, the brass and the technopolymer FCM. 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.
