Tube system, tube with sealing element and method for manufacturing a component consisting of a tube and a sealing element

摘要

The system (8) has a sealing unit (12) injected into a pipe (10), where the pipe and the sealing unit are connected with each other. The pipe and the sealing unit are manufactured as two-component-injection moulded part. Multiple recesses (18) are provided in the pipe and multiple complementary projections (20) are provided in the sealing unit such that the pipe and the sealing unit are connected in a form-fit manner. The sealing unit lies between the pipe and another pipe (14) in a radial direction. The pipe is made of polypropylene, and the sealing unit is made of thermoplastic elastomer. An independent claim is also included for a method for manufacturing a group of pipes and a sealing unit.
