Tests have shown that as the back pressure experienced by a pumping system approaches the working pressure ratings, tubing life is reduced. Working pressures are calculated at a 1:5 ratio relative to burst pressure.

This information can be used to calculate the working pressure of a specific tubing. Using the pressure ratings for peristaltic pump tubings chart and the calculation of working pressure chart, multiply the appropriate value shown times (x) the number provided below. For example: 1/16 inch I.D. Tygon® B-44-3 tubing would be 70 psi x 1.43 = 100.10 psi working pressure.
