• F40 Tubing kit
The F40 Tubing kit is identical to the F10 kit (described previously), however, all orange PEEK
tubing is replaced with PEEK, green, 1/16” OD x 0.03” ID tubing. The large bore tubing is designed
for use with the higher flow rates when using the Maximizer or F40 Workstation pumps.
• Maximizer Tubing kit
The tubing kit that accompanies the Maximizer for connecting the reagent bottles to the valves is
composed of FEP PTFE, 1/8” OD x 0.062” ID. Each length of tubing is color coded to identify its
connection site and solution.
Inlet A1 uses red tubing and is used for acid solutions. Inlet A2 uses blue tubing and is used for
base solutions. Inlet B1 uses yellow tubing and is used for water solutions. Inlet B2 uses green
tubing and is used for salt solutions.
The kit includes an installation chart.
• Maximizer Interconnect Tubing kit
This kit contains cut and fitted tubing to connect the Workstation pumps A and B inlets to the
Maximizer valves A and B outlets. There are two preformed PEEK 1/8” OD sets of tubing in this kit.
• pH Montior Tubing kit
The pH monitor includes cut and fitted tubing to connect the pH flow cell to the Conductivity flow
cell. There is a length of PEEK, orange, 1/16” OD x 0.02” ID tubing rated to 5000 psi and a length of
PEEK, green, 1/16” OD x 0.03” ID tubing rated to 3000 psi for higher flow rates.
2.9.4 Fittings Tightener
The fittings tightener is designed to apply appropriate tightness to the nut, stainless steel lock ring, and the
ferrule, when installing 1/4-28 fittings on the end of tubing. The flattened end of the lock ring should face
towards the nut with the tapered end facing the tapered end of the brown ferrule. Place the tubing and
fittings into the green fittings tightener. Do not allow the tubing to slip out of the ferrule. Tighten the fitting to
seat the ferrule onto the tubing, but do not over-tighten. Once the fitting is made, it can be inserted into the
port. Refer to instructions on next page.
