Masterflex I/P Tubing Options
Achieve top performance from your Masterflex I/P pump heads when you use precision-extruded tubing. Tubing is manufactured to tight tolerances that match our I/P pump heads. Choose from precision tubing or high-performance precision tubing. High-performance precision tubing has a thicker wall that improves pressure generation, suction lift, ability to pump viscous fluids, and tubing life. Choose from over a dozen different formulations.
