Abstract

A tube (1) of elastomeric material for an air conditioning system (I) or for other system which is on-board of a motor-vehicle is herein described. The tube (1) is intended to be fitted over a metal connecting element (2) and to be locked onto the latter by means of a crimping operation that envisages the clamping around the tube (1) of a metal clamping element (3). The tube (1) comprises at least one body (C) made of polymeric elastomeric material supplemented with carbon-based nanofillers wherein an outer surface with one or more piezo-resistive areas (4) is provided, where the polymeric material supplemented with carbon-based nanofillers has been made locally piezo-resistive by means of laser irradiation (L). The piezo-resistive areas (4) arranged on the body (C) of polymeric elastomeric material of the tube (1) can be used for verifying the correct execution of the crimping operation
