pneumatic push-in fittings system LF 3000 Invented and launched by Legris in 1969, the LF 3000 system has become universally adopted. It has been designed using a simple and widely proven operating principle which allows instant fitting. The connection of tube to fitting is made by simply pushing the tube into the fitting, no other operation is required. Disconnection is similarlyinstantaneou. Attentive to market needs, Legris has taken into account the requirements of its customers, i.e. opti- misation of performance, miniaturization and appearance. In order to be utilised to its maximum capability, the LF 3000 system is available in 3 ranges : - for metric tubing with BSP threads in taper, parallel or metric form. - for fractional inch tubing with BSP threads in taper form. - for fractional inch tubing with NPT threads. Millions of fittings are in service throughout the world. Designed for pneumatic installations, the LF 3000 system is therefore an essential component in a wide variety of industries. technical specifications suitable compressed air LF 3000 can also be used for fluids Reliable performance is dependent upon the type of tubing conveying various types of liquids (water, cutting oil, etc) for industrial being used, ambient temperature and fluid conveyed applications. The working pressure, together with the suitability of component materials of from 0 to 6 / 10 bar, and temperatures, from 0 to 60C, are dependent upon the the fitting, according to the application. fluid conveyed and the type of O ring used.
