Abstract: A fitting for attaching to a threaded connection of a pipe, in particular a water pipe, includes a basic body, a threaded portion, and a sealing body arranged on the threaded portion. The basic body has a pressing surface on the side situated opposite to the threaded portion. Also disclosed is a method for attaching a fitting to a threaded connection of a pipe.

Abstract: The invention relates to a fitting for producing a leaktight connection with a pipe end, having at least one pressing portion designed for pressing and the insertion of a pipe end, having at least one sealing and at least one retaining element. The sealing and retaining elements are arranged in the pressing portion. The retaining element is substantially annular. The annular shape defines axial and circumferential directions. The retaining element has two ends with respect to the circumferential direction. Specifying a fitting with a retaining element is achieved when the retaining element has, at each of the two ends, at least one contact surface extending at least partially in the circumferential direction. The contact surfaces are designed to be brought into contact with one another upon pressing the pressing portion. The invention relates to a system and method for producing a leaktight connection between a pipe end and fitting.

Abstract: The invention relates to a fitting for attaching to a threaded connection of a pipe, in particular a water pipe, with a basic body (20), with a threaded portion (22) and with a sealing body (24, 50, 56; 62) arranged on the threaded portion (22), in which the technical problem of simplifying the attachment to a threaded connection of a pipe and configuring the attachment to be more reliable at the same time is solved in that the basic body (20) has a pressing surface (26, 66) on the side situated opposite to the threaded portion (22). The invention also relates to a method for attaching a fitting to a threaded connection of a pipe.
