Transition means between fittings dimensioned to one standard and pipes dimensioned to another standard

摘要

An adaptor 17 for the connection of a polymeric pipe 10 to a filling 13 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. The fitting 13 includes a fitting nut 23, threadedly engaged with the fitting body, a deformable gripping member 14 with internal barbs 17 which engage the outside of the pipe 10 and also presses the pipe 10 over the external barbs 36 of the inserted spigot 28, and an elastomeric seal 38 which seals against the other end 35 of the spigot 28.
