Abstract

A transition means for the connection of a polymeric pipe (10) to a fitting (13) which is dimensioned to accommodate pipes (10) of slightly different diameters, and comprises a double-ended hollow spigot (28) with one end (27) having an outer diameter which is appropriate for a standard fitting (13) and the other end (35) having radially projecting barbs (36) of diameter to engage the inner surface of a pipe (10) with an interfering fit, so arranged that upon assembly to a fitting, the transition barbed end (35) can be driven into the bore of a pipe end, the other end can be accommodated by the fitting (13), and upon tightening of a fitting nut (23), a deformable gripping member (14) with internal barbs (17) contained within the fitting (13) can engage the outside of the pipe (10) and also can press the pipe over the external barbs (36} of the inserted spigot.
