Rigid tubing, particularly for use in the engine compartment of a motor vehicle, and method for its manufacture

摘要

The tubing (10) comprises a tube (12) of metallic material, one or two connecting endpieces (14) of elastomeric material, each co-moulded on a respective end portion of the tube (12) and, for each connecting end-piece (14), a respective reinforcing insert (16) of metallic material inserted into the tube (12) at the end portion on which the connecting end-piece (14) is provided. Preferably, the metallic tube (12), the reinforcing inscrt(s) (16) and the connecting end-piece(s) (14) are made of light alloy, steel and thermosetting elastomer, respectively. A layer of adhesion-promoting agent is advantageously deposited on the surface of the metallic tube (12) which is intended to interface with the connecting end-piccc(s) (14).
