To insert rings into groove:
1. Lubricate the entry chamber.
2. Place the ring over the conical top of the plug so that the
lips of the ring face to the pressure (see Figures 7 and 8).
3. Slip to the ring into the groove (without spinning it) as
shown in Figure 8. This operation can be facilitated by
heating the ring. The temperature of the ring should not
exceed 180°C (356°F).
4. Keep the ring retained until it returns to room temperature
and goes back in place within the groove. Clamping with
a collar (SERFLEX type) will help to properly position the
ring.
Assemble the direction of radial rings (B108 and
B118) on the plug and on the cage (see Figures 6 and
7). Flow tends to open; the open side is in the top.
Flow tends to close: the open side is in the bottom.
