he LBP technology, through the special design of the o-rings, makes it possible to detect a water leak during the testing phase of the system if the fitting has not been pressed. The main features of the SESTA LBP fittings are: suitable for connecting multilayer pipes of the following dimensions: 16;20;26;32 brass alloy body CW617N coloured, non-detachable plastic bushing holder, which prevents contact between the aluminium and the multilayer pipe and the brass of the fitting and thus ensures the absence of electrochemical corrosion phenomenaAISI 304 stainless steel bushing o-ring certified EPDM PEROX 70, peroxide-cured
