ABSTRACT:
Shown and described is a variable size pipe connector which may be cut into one or more segments and is used to connect together pipes having different inside diameters. A pair of hose clamps is used to secure the connector in place and assure a fluid tight seal. The connector may have external indicia indicating cut lines directly dimensionally related to the diameters of pipes to be connected together. PVC and similar thick walled pipe ends may be grooved to further assure integrity of the seal between connector and pipes when clamped thereabout by hose clamps and metal pipe ends may be flared for the same purpose.
