ABSTRACT:
A clamp connector for pipes, of a type for use in a water service line, comprising a connector housing (1) having internal threads (2) for engagement with a clamping nut (3) having external threads (4) and a conical portion (5) extending axially from the threads (4) intended to engage with the base (6) of the connector housing, the leading portion of the cone (5) being intended, when the clamping nut (3) is tightened, to be pressed into sealing and retaining engagement with a pipe (7). The base (6) of the connector housing has two conical portions (9,11) separated by a cylindrical section (12) the two conical portions (9,11) being intended to engage with two clamping nuts (3) having different orifices corresponding to a different size outside diameters of the pipes that are to be coupled to the connector housing (1). The clamp connector can thus be used to connect pipes having different outside diameters in a tee-connector.
Transition member (13) whose external configuration corresponds to the clamping nut (3) and whose internal configuration corresponds at least in part to the housing (1), together with a clamping nut (3) of suitable dimensions for being screwed into the transition (13), is provided for connecting a pipe of smaller dimensions than other pipes coupled to the connector housing (1).
