In
Figure
3, the grip ring may become cocked inside the casing when it
comes in contact with the spigot during assembly. If this occurs, assembly
forces increase dramatically.
If the gap in the grip ring is too narrow, the grip ring should be removed from
the casing. Then, the gap can be increased by manually springing the ring
apart as shown in
Figure
4. Thick gloves are recommended as the teeth on the
grip ring are quite sharp. Once the gap has been increased, re-install the grip
ring in the casing.
Figure 4
Note, when re-installing the grip ring, the grip ring should be oriented such
that the tapered end of the grip ring matches the tapered end of the casing
pocket. If the grip ring is installed backwards, it will not be able to be
rotated easily inside the casing. Moreover, it will not be possible to make the
joint.
