T-321 stainless steel exhaust flex hose is an economical solution for a flexible connection between the engine and the exhaust piping. Exhaust flex is most commonly used in noncritical applications, such as stand by generators. Our line of Isoflex exhaust flex hose assemblies are designed to outperform standard flex assemblies over time. The most common failures with standard exhaust flex assemblies occur at the heat-affected zone, due to annealing that is created by the welding process. Isoflex products remove the heat effected zone with spacialized weld techniques. For all critical applications, we recommend the use of our Triad CycleMAX multi-ply bellows to insure that your system will function as you intend. Our engineering staff is ready to assist you in choosing the right product for your specific application.
