Fep-Lined Suction Line; Attaching A Strainer - Teledyne 4700 Pocket Manual

2.4.2 FEP-lined Suction Line

Inserting a tube coupler into FEP-lined suction
line will damage the thin lining. Instead, refer
to Figure 2-8 and the instructions below to
attach FEP-lined suction line to the pump tube:
1. Slide a suitable clamp over the pump tube
inlet.
2. Push about 20 mm of the FEP-lined suction
line into the end of the pump tube.
3. Slide the clamp over the union and tighten.
Do not overtighten; this might cause the
tubing to collapse or restrict the flow.

2.5 Attaching a Strainer

To select the right strainer for your application,
see Table 2-2 and Figure 2-9.
To attach the strainer to the suction line,
carefully screw the strainer's threaded
connector into the suction line. If attaching the
strainer to an FEP-lined suction line, heat the
end before threading the strainer into the line.
Warming FEP-lined tubing will make it more
pliable to avoid damage.
