2. Slide the nut, stainless steel compression ring, and the ferrule, in that order, onto the tubing as
shown in Figure 4-2. The flattened end of the compression ring should face towards the nut with the
tapered end facing the tapered end of the brown ferrule.
The stainless steel lock ring is not in the fluid path, so biocompatibility is maintained.
3. Allow the tubing to extend slightly beyond the end of the ferrule.
4. Place the fitting and tubing into the green fittings tightener. Do not allow the tubing to slip out of the
ferrule.
5. Tighten with your fingers to seat the ferrule onto the tubing, but do not over-tighten. The ferrule
should be flush with the tubing.
6. Once the fitting is made, the compression ring and ferrule should adhere to the end of the tubing
while the nut will be moveable.
4.2 PLUMBING A DUOFLOW SYSTEM
This section discusses how to create your own plumbing arrangement of a DuoFlow system. The plumbing
for each of the DuoFlow valves is discussed later in the chapter.
The Fittings Kit includes an F10 tubing kit that includes all tubing required for a basic installation. Refer to
Figure 4-1.
