An apparatus and method for joining pipes includes a plate for melting mating surfaces of the pipes to be joined. Additionally, the apparatus utilizes a vacuum in order to push the first and second pipes together in lieu of hand or mechanical pressure which may be inconsistent. Additionally, the vacuum allows the pipes to be joined to settle on each other in order to create a pressure about a periphery of the end of the pipe being joined to the other pipe. The consistent pressure creates a very strong joint between the first and second pipes.

A conduit-coupling adaptor configured for mutually joining conduits of disparate diameters includes a central conduit with interior and exterior surfaces extending longitudinally between central-conduit first and second ends. The central-conduit first and second ends define, respectively, first-end and second-end coupling sleeves that extend longitudinally in opposite directions and terminate at, respectively, first and second openings. The coupling sleeves can be implemented, alternatively, as male or female coupling members relative to other conduits. A first-end skirt includes a skirt wall concentrically disposed about at least a lengthwise portion of the central-conduit first end. The skirt wall has skirt-wall inside and outside surfaces that longitudinally co-extend with at least a portion of the first-end coupling sleeve and are joined to the central-conduit wall by a shoulder. The skirt-wall inside surface defines a socket that is configured as a female connector for insertably receiving a male coupling member of another conduit.

A snap fitting far use in plumbing is provided. The snap fitting includes a main body formed of plastic and shaped to extend partially around a cylindrical pipe to snap over the pipe and an inset for extending from an interior side of the main body into a hole in the cylindrical pipe.
