Specifications
Tubing operating life test were done at 600 RPM, with 20°C water,
0 PSI, back pressure until the tubing breaks. Average tubing life
hours are shown. However, tubing life varies considerably
depending on tubing formulation, tubing back pressure, and fluid
pumped. Tubing should be inspected periodically for wear.
