5.2.1. Rubber Seal Joint (RSJ) with pipe stop
- Clean the spigot and socket end thoroughly with a clean cloth before jointing.
Do not use material like dusters in order to avoid fibres from sticking to the surface of the seal.
- Check both pipe ends for damage.
- Mark the depth of entry on the spigot end.
- The measurement of the mark on the spigot end is as follows:
depth of the socket end (dimension A) minus end play (dimension C) (see fig.5.2.a. and table 5.c., page 20).
- Position the rubber ring into the groove of the spigot end.
- Use a round tool like a screwdriver underneath the rubber ring and work it around
a few times in order to distribute the tension (see fig. 5.2.d., page 17).
