3. Insert the pipe in to the socket without the seal ring and mark along the pipe, when it is fully Inserted.

4. Fix the rubber ring in the groove without twisting it.

5. Apply jointing lubricant to the chamfered end of the pipe, up to the mark made on spigot or to the socket end of fitting.

6. Push the pipe firmly into the socket till the gap between the mark on the spigot and the socket is about 10mm to allow thermal expansion.
