Abstract
A screw part with an annular cross-section and having a base element that is hollow, cylindrical and at least partially injection-molded from a plasticized polymeric mass containing fibers. The base element includes at least one internal and/or external thread and an inner channel for arranging and/or passing through a conduit system element. The inner channel has at least one sealing section for sealing with the conduit system element and/or at least one support section for supporting and/or guiding the conduit system element and/or at least one retaining section for directly or indirectly locking the conduit system element. An insertion sleeve is arranged in the base element coaxially with the inner channel. The insertion sleeve is at least partially encapsulated by the polymeric mass with the polymeric mass facing radially towards the inner channel and radially away from the inner channel. A process for manufacturing such a screw part.
