A press fitting for a pipe connection is provided. The press fitting includes a fitting body for connecting the press fitting to a pipe, a press sleeve fixed to the fitting body and having a substantially cylindrical pressing portion and at least one projecting element which delimits the substantially cylindrical pressing portion in the axial direction, and a tubular banderole which surrounds the substantially cylindrical pressing region of the pressing sleeve, wherein the tubular banderole is arranged rotatably relative to a surface of the pressing sleeve, is held in the cylindrical pressing region by the at least one projecting element and is at least partially destroyed when the pressing sleeve is pressed with a pressing tool.

A connecting joint includes a connecting tube and a first compression sleeve. The connecting tube includes a first tube connecting section for connecting a first tube and a second tube connecting section for connecting a second tube. The first tube connecting section and the second tube connecting section are communicated and an annular connecting plate is arranged therebetween. The first compression sleeve is sleeved on the second tube connecting section. A first insertion hole is formed between an inner wall of the first compression sleeve and an outer wall of the second tube connecting section. A first annular groove is formed in an outer surface of one end of the second tube connecting section. An end portion of one end of the first compression sleeve close to the annular connecting plate is bent toward the second tube connecting section and inserted into the first annular groove.

A quick connector is disclosed comprising a receptacle having first and second channels formed on opposite sides of the exterior of the receptacle. A flange includes a retainer mounting part fixed on a first end of the flange. A first pair of clamping jaws extends from a second end of the flange with each clamping jaw of the first pair of clamping jaws accepted into a respective receptacle first and second channel, clasping the receptacle to the flange. The clamped bracket retainer and receptacle are then guided to have a tube inserted into an interior passage of the receptacle and the bracket retainer is attached to a rigid structure using a fastening arrangement that retains the quick connector receptacle and endform in a connected state.

The invention relates to a press fitting for a pipe connection, comprising a fitting body for connecting the press fitting to a pipe, a press sleeve fixed to the fitting body and having a substantially cylindrical pressing portion and at least one projecting element which delimits the substantially cylindrical pressing portion in the axial direction, and a tubular banderole which surrounds the substantially cylindrical pressing region of the pressing sleeve, wherein the tubular banderole is arranged rotatably relative to a surface of the pressing sleeve, is held in the cylindrical pressing region by the at least one projecting element and is at least partially destroyed when the pressing sleeve is pressed with a pressing tool. The invention further relates to a method for manufacturing such a press fitting.

An end-form fitting includes a tube and an auxiliary component disposed around the tube. One of the tube and the auxiliary component is deformed to cause the auxiliary component to engage the tube in order to militate against relative movement between the tube and the auxiliary component. The auxiliary component includes an array of surface irregularities formed therein and configured to engage an outer circumferential surface of the tube to form a corrugated joint therebetween. The auxiliary component is formed to include a radially outwardly extending orientation structure for establishing a rotational orientation of the end-form fitting when being coupled to a complimentary end-form fitting.

A hose coupler generally includes a hose adapter including opposing ends, an interior surface forming a fluid passage between the opposed ends, and an exterior surface including a series of barbs for engaging an interior surface of a hose that is configured to be fluidly connected to the hose adapter. A ferrule is connected to the hose adapter and is positioned to at least partially surround the exterior surface of the hose adapter. The ferrule has an interior surface facing the exterior surface of the hose adapter. The interior surface defines at least one cutting rib having a sharp corner or edge for piercing an outer layer of the hose and a plurality of compression ribs each defining a rounded surface for compressing the hose against the barbs.

A high pressure pipe coupling construction includes at least one high pressure pipe (2) as well as a coupling (22) connected to the pipe (2). The pipe consists a reinforcement layer (4) of helically arranged fibers (6, 7) and the coupling (22) consists an inner sleeve (23) sealed with respect to the inner surface of the pipe and at least one metal outer sleeve (9). The metal outer sleeve (9) has an overlapping outer sleeve part (29) overlapping the inner sleeve (23) in axial direction and a protruding outer sleeve part (25) protruding in axial direction with respect to the inner sleeve (23), which overlapping outer sleeve part (29) and protruding outer sleeve part (25) are connected to the outer surface of the pipe (2). The inner sleeve (23) consists of a plastic material; at the location of overlap between the inner sleeve (23) and the pipe (2), the maximum outer diameter of the inner sleeve (23) is smaller than or equal to the minimum inner diameter of the pipe (2).
