TABLES Tab. 1 Pressing tools compatible with Eurotubi Pressfitting System Brand - Usable range - Diameters available All the machines, adapters, jaws and chains declared by the manufacturer to be suitable for profile “M” pressing. For the mini model, the use for stainless steel Ø 35 is still being validated. WARNING! 1) The systems with diameters 42 => 108 are compatible exclusively with chain terminals with a minimum of three sectors. Jaw terminals for diameters 42 and 54 are not accepted as valid, under penalty of the guarantee being voided. 2) “Dated” models are considered valid if they guarantee the same performance as those currently commercially available. 3) All models must undergo periodic annual revision, under penalty of any guarantee being voided.
