Tygothane<span class="sup">®</span> Precision Polyurethane Pressue Tubing

Tygothane® Precision Polyurethane Pressure Tubing
Formulation C-544-A I.B.

Because of its excellent wear properties, Tygothane® frequently outperforms rubber, plastic and metal materials in the most physically demanding applications.

More flexible than many other reinforced urethane tubings, Tygothane® Pressure Tubing can be used in the most physically demanding applications, such as those requiring a tight bend radius. Specially formulated from tough, ether-based polyurethane resin, Tygothane® tubing is resistant to a range of chemicals, including oils, greases, solvents and chemicals.

Because of its excellent wear properties, Tygothane® frequently outperforms traditional rubber, plastic and metal materials when exposed to abrasive conditions. Tygothane® also is plasticizer-free, and remains flexible even when cycled through temperature extremes.

*NSF has length restriction, determined by tubing size, for NSF 61 applications.
