Tygon S3 Pressure Tubing #B-44-4X I.B. (Formerly "Pressure Tubing")

Tygon S3 Pressure Tubing #B-44-4X I.B. (Formerly "Pressure Tubing")

Reinforced for elevated working pressure, Tygon S3™ Pressure Tubing is the most flexible of the reinforced tubings available today.


Tygon S3™ B-44-4X I.B. can be used to transport many types of fluids in applications ranging from those regulated by FDA guidelines to industrial laboratory applications involving virtually all non-solvent based chemicals.

Lightweight and easy to handle, Tygon S3™ B-44-4X I.B. goes into service quickly. It readily curves around corners and obstructions, requiring a minimum of couplings and fittings. Its flexibility can save up to one-third the footage and much of the labor required to install rigid stainless steel, glass tubing or piping.

Tygon S3™ B-44-4X I.B.’s smooth non-porous inner bore resists particle entrapment and resultant bacterial growth. Its excellent non-wetting properties facilitate complete drainage and increase the overall effectiveness of cleaning, making it the ideal choice in food, beverage, dairy, and other bacterialsensitive applications. Custom antimicrobial version available upon request.
