Development of a reusable mechanical Purge End fitting which can be used instead of both the EF fittings used during laying of P.E. mains for sizes 63mm, 75mm, 90mm and 125mm. This would eliminate the waste on site and also reduce the time spent during the operation, as electro fusion of these fittings will no longer be required.This is a proposal to replace the EF top tee and end cap, which are single-use products, with a reuseable mechanical fitting.

This is a proposal to replace the EF top tee and end cap, which are single-use products, with a reuseable mechanical fitting.

Specific success criteria are:

design and manufacture of prototype units resulting in successful proof of concept laboratory testing

Fitting achieving 20 uses before requiring servicing or replacement during field tests
