9Specifications
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.
