A pipe adapter includes a first tubular element having a first portion, a second portion axially adjacent the first portion, and a securing portion adjacent an end of the second portion opposite the first portion, the second portion defining a socket; a second tubular element having a first portion and a second portion axially adjacent the first portion, the first portion defining a distal end sized for insertion into the socket and having a radially extending stop; an annular sealing member. The securing portion is formed integrally with the second portion of the first tubular element and has a flange portion contacting the stop to secure the second tubular element axially relative to the first tubular element while also allowing the second tubular element to rotate relative to the first tubular element.

A coupling apparatus for use in sealingly connecting a first fluid flow path to a second fluid flow path. The coupling apparatus includes a rigid fluid flow channel having a first end and a second end, wherein the fluid flow channel is substantially rigid in an axial direction and a radial direction, a first sealing terminus that is rigidly connected to the first end and that is configured for sealing with the first fluid flow path, and a second sealing terminus that is slidingly disposed about the second end such that the second sealing terminus is configured for relative movement with respect to the second end, and wherein the second sealing terminus is further configured for sealing with the second fluid flow path. The coupling apparatus further includes a flexible coupler connected to both the first sealing terminus and the second sealing terminus and surrounding the fluid flow channel, wherein the coupler is relatively more flexible in the axial direction and the radial direction as compared to the fluid flow channel.

A connector providing a rotating snap connection for connecting tubes, hoses and/or other conduits where the rotatable portion of the connector snap fits with the remaining portion of the connector is described. A first connector can include a body defining a first internal passage, a connecting end defining a second internal passage, and a connecting mechanism rotatably connecting the connecting end to the body such that the second internal passage of the connecting end is fluidly connected with the first internal passage. A second connector can include a first body, a second body rotatably connected to the first body via a connecting structure, and a connecting structure.

An improved device for coupling rigid non-metallic conduits is disclosed. The claimed device is capable of allowing movement in an axial direction due to expansion and contraction and can also compensate for angular or parallel deflection of the conduits.
