Adaptor for use with multi-layered pipe

摘要

A pipe insert or adaptor 1 for use with a length of multi-layered barrier pipe comprises two axially adjacent and mutually coaxial cylindrical sleeve portions 3,5. The relatively smaller sleeve portion 3 is provided with a seal on its radially outer surface for sealing against the inner surface of a multi-layered pipe. The outer diameter of the larger sleeve portion 5 is similar to the outer diameter of the pipe 41 and cooperates with a seal 29 in a pipe fitting 21. The two sleeve portions are joined together by an axially-facing shoulder 11, which covers the end surface of the pipe 41 when the first sleeve section 3 is inserted in the end portion of the pipe for use.
