MTI® Hose

MTI® (Membrane Tube Infusion) Hose is a cutting edge tubing used to optimize the vacuum infusion process. The MTI® Hose is designed with a flexible spiral hose encased with a microporous membrane that is permeable to gas but impermeable to resin. The integrated spiral tubing provides for an effective airflow channel while the semi-permeable membrane creates a barrier effect that prevents resin from entering the hose. This self-regulating MTI® process supports uniform resin content, increased resin control and a pinhole-free finish in one shot.

Unlike with typical spiral tubing products, the risk of dry spots and impact of air bubbles are minimized with the use of the MTI® Hose. A resin trap is no longer necessary, so exact resin consumption can be calculated.

The MTI® Hose has a 5/16” ID with a 1/2“OD. It is compatible with epoxy and polyester resin systems and is suitable for vacuum infusion applications up 175 °F (80°C).
