Abstract: A fitting for connecting to a pipe, including a base body having at least one pipe section, a pressing section connected to the pipe section, and a functional unit connected to the pressing section. The functional unit includes a functional ring, a sealing element and a fixing element, wherein the functional ring, has an outer section arranged radially outside the pressing section and an inner section arranged inside the pressing section, and wherein the inner section positions the sealing element and the fixing element inside the pressing section. The fitting solves the technical problem of enabling easier and more reliable replacement of the functional parts. The invention also relates to a functional unit and a system.

Abstract: A press connection system for non-releasably connecting a fitting to a pipe, with a press jaw, with a press contour formed on the inside of the press jaw. The press contour has a cylindrical press section, with a fitting, with a fitting base body and a press sleeve forming a press chamber. A sealing ring is arranged at the proximal end of the press chamber relative to the fitting base body and a cutting ring is arranged at the distal end of the press chamber relative to the fitting base body. The cutting ring has a central cylindrical section and cutting elements arranged at the distal end and cutting elements arranged at the proximal end. Also a swaged fitting.

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.

Abstract: A fitting for thick-walled pipes, having a contact region and a pressing region, the pressing region being arranged on the side of the contact region facing towards the pipe insertion opening, and the wall thickness in the pressing region being at least in sections less than the wall thickness in the contact region. The invention also relates to a method for producing a fitting for thick-walled pipes, in which a thick-walled pipe is radially widened in a fitting region arranged at one pipe end so that the internal diameter of the fitting region corresponds substantially to the external diameter of the pipe and the wall thickness in the fitting region corresponds substantially to the wall thickness of the rest of the pipe.

Abstract: A flange connection for pipes, especially for sanitary installations. The flange connection comprises a connecting piece which can be joined at each end to a pipe to produce a sealed connection. The flange connection further comprises a flange which is arranged radially outside on the connecting piece and which is fixable to a further component to make an indirect connection between the connecting piece and the further component. The flange has an opening through which the connecting piece is guided and the flange is fixed on the connecting piece by a retaining element.

Abstract: A flange connection for pipes, especially for sanitary installations, including a connecting piece (1), which can be joined at each end to a pipe to produce a sealed connection, and a flange (2), which is arranged radially outside on the connecting piece (1) and which is fixable to a further component by a fixing device to make a connection between the connecting piece (1) and the further component.
