A press fitting device (1) for establishing a fluid-tight connection with at least one pipe section (10), the press fitting device being configured to generate a sound when a gaseous fluid flows along or through the press fitting device a) in a pre-press fit condition, in which a connection with the at least one pipe section is established and before the connection is press-fit; and/or b) in a press fit condition, in which the connection is press-fit, if the connection is not fluid-tight.

A profiled leak-before-press sealing ring includes a plurality of arc-shaped first and linear-shaped second type ring portions that lie alternating around a center axis. The second type ring portions extend linear-shaped with straight inner and outer surfaces in a tangential direction. The first type ring portions have curved inner and outer surfaces of constant radii around the center axis. The ring further includes a plurality of third type ring portions that extend arc-shaped in between respective ones of the arc-shaped first and linear-shaped second type ring portions, and that each connect with its head ends to head ends of neighbouring ones of the first and second type ring portions. The arc-shaped first, the linear-shaped second, and the arc-shaped third type ring portions all have a same evenly large dimensioned cross-sectional shape.

An assembly configured to be press joined with a pipe by a pressing tool includes a piping component, which includes a body, a first end having a rim and an inner surface having a plurality of grooves, and a sealing recess wall positioned between the first end and the body and defining a sealing recess. The assembly also includes a sealing element received within the sealing recess of the piping component and having a sealing element thickness. The sealing element thickness of the sealing element is about equal to and not less than a Minimum Sealing Element Thickness Value of the sealing element.

A piping component for a press fitting is provided that includes a body comprising a body inner diameter. A first end includes a first end inner diameter and an inner surface. A sealing recess is positioned between the first end and the body. The inner surface includes a plurality of grooves. The plurality of grooves is integrally formed with the first end and comprises a blunt surface configured for a press fit between a pipe and the piping component. The plurality of grooves comprises a groove inner diameter that is within about 10% of the body inner diameter and the first end inner diameter. The plurality of grooves includes an angled edge.

A press fitting device (1) for establishing a fluid-tight connection with at least one pipe section (10), the press fitting device being configured to generate a sound when a gaseous fluid flows along or through the press fitting device a) in a pre-press fit condition, in which a connection with the at least one pipe section is established and before the connection is press-fit; and/or b) in a press fit condition, in which the connection is press-fit, if the connection is not fluid-tight.

Provided is a pipe connecting sealing member including a projection part includes a body part that is provided between the outer surface of the pipe and the inner surface of the connector to which the pipe is inserted, and is formed to extend in a ring shape along a circumferential direction; and the projection part that is formed in a spiral shape forming an unlimited orbit and projects along the outer surface of the body part.

A mechanical coupling for joining pipe elements has a seal. The seal has sealing surfaces with one or more projections that form closable leak paths between the coupling and pipe elements being joined. The leak paths close when the coupling is properly installed. Otherwise, the leak paths remain open to ensure that improperly installed couplings can be discovered during pressure testing and before service pressure is applied.

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.

An assembly configured to be press joined with a pipe by a pressing tool includes a piping component, which includes a body, a first end having a rim and an inner surface having a plurality of grooves, and a sealing recess wall positioned between the first end and the body and defining a sealing recess. The assembly also includes a sealing element received within the sealing recess of the piping component and having a sealing element thickness. The sealing element thickness of the sealing element is about equal to and not less than a Minimum Sealing Element Thickness Value of the sealing element.
