CONNECTING ARRANGEMENT FOR PIPES

摘要

The invention relates to a connecting arrangement for connecting a pipeline (1) to a connection piece (2) of fuel or hydraulic systems, in particular fuel distribution systems. The pipeline (1) can be connected to the connection piece (2) by means of a connecting element (5) in the form of a union nut. A sealing head (10) which has a sealing surface (13) and a pressure surface (14) is provided at the end side of the pipeline (1). The union nut serves to press the sealing head (10) by the sealing surface (13) in a pressure-tight manner against a sealing seat (21) formed in the connection piece (2). Leakage paths (23) are provided at the rear side of the sealing head (10) outside the sealing surface (13) and the sealing seat (21). The leakage paths (23) function as predetermined leakages and ensure that sealing outside the actual sealing region of the connecting arrangement is prevented. As a result, tightness testing by means of sniff tests is more reliable.
