I/P® Pump Tubing

Manufactured to tight tolerances of Masterflex® pump heads to ensure accurate flow rates and long tubing life

Optically inspected and factory tested—ensures clean, defect-free tubing that performs to specifications

Fourteen pump tubing formulations are available, each with different chemical compatibility properties, agency approvals, and performance characteristics

Norprene®, PharMed® and Tygon® formulations are the firmest we offer; C-FLEX® and silicone are the softest

Firm tubing has longer life, better pressure generation, stronger vacuum/suction lift, and lower gas permeability than soft tubing
