The conduit structure comprises an outer tubular housing having a tubular inner member disposed therein with a first end of the inner member being positioned in the medial portion of the outer housing and retained therein by means of an outwardly extending flared portion on the first end of the tubular inner member which is constrained between two longitudinally spaced inwardly extending annular projections formed on the inner surface of the outer housing. A resilient annular seal is provided between the outer surface of the tubular inner member and the inner surface of the medial portion of the outer housing. The tubular inner member extends from one end of the outer housing and a second resilient annular seal is provided between the tubular member and said end of the outer housing. The tubular inner member is adapted for longitudinal, radial and rotational movement relative to the outer housing. An alternate form of conduit joint provides a second tubular inner member having one end secured and sealed within the medial portion of the outer housing in the same manner as the first tubular inner member and having the opposite end thereof extending from the second end of the outer housing. The two embodiments of the conduit joint can be combined as a single conduit joint assembly. A method of constructing the conduit joint from synthetic organic polymeric thermoplastic material is also disclosed.
A method of assembly of a conduit joint having a unitary tubular outer housing formed of thermoplastic material capable of being permanently deformed upon application of sufficient heat and pressure thereto comprising a medial portion and first and second opposite end portions, a first tubular inner member having at least one flared end, and a resilient annular seal, comprising the steps of:
