Tubing retention systems are described herein. A tubing retention system includes a spigot, a tubing, and a collar. The spigot includes a spigot body and a spigot extension extending from the spigot body, wherein the spigot extension comprises a flared portion opposite to the spigot body and the spigot body and the spigot extension cooperatively define a spigot lumen. The tubing includes an outer surface and a tubing lumen, wherein a coupling portion of the tubing is disposed around the spigot extension, permitting fluid communication between the tubing lumen and the spigot lumen. The collar is disposed radially around the outer surface of the tubing and axially between the flared portion and the spigot body, wherein the collar radially engages the coupling portion of the tubing disposed around the spigot extension to axially and radially retain the tubing with the spigot.

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 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 compression collar is manufactured for use in reinforcing an interference fit between an end of a pipe and a fitting. A precursor form is injection molded using a cold-expansion material. The precursor form has a tubular body with an initially closed axial end and a bore that is initially blind formed in the other axial end. Material is removed from the initially closed axial end of the tubular body of the precursor form to form an opening in the initially closed axial end that connects to the bore thereby forming the compression collar. The opening has an inner periphery with a profile in axial cross section that is different than any profile in axial cross section of an inner periphery of the bore. The collar formed may lack knitlines and may include tabs formed during the removal step which help to position the collar on a pipe.

A hose assembly includes a hose, a connector body, and a collar. The connector body has an outer end portion defining a fluid connector, an inner end defining a nose portion received in an inner bore of the hose end portion, and an intermediate portion including first and second annular flanges spaced apart to define a dog lock groove. The collar includes an outer end portion defining an inner radial dog lock received in the dog lock groove, an annular step portion extending radially outward of and axially inward of the dog lock in axial alignment with the first annular flange, and an inner end portion extending radially outward of and axially inward from the step portion, the inner end portion being in radial compression against an outer surface of the hose end portion.
