Multi layer tube

Multi layer tube


With our co-extrusion process, our seamless tubing meets critical design tolerance. Ideal for handling high pressure evenly, such as a balloon catheter.

Our Multi layer tube, with high concentricity (more than 90%), enables the catheter to handle high pressures consistently and effectively. With the co-extrusion process, unlike welded tubing, our seamless precision tubing meets critical design tolerance. Ideal for the application requires handling high pressure evenly, such as a balloon catheter, for ensuring a tight fit between balloon and blood vessel.
