Internally Insulated, Zero-Leak, Torsional And Non-Torsional Bellows

Tru-Flex Metal Hose introduces its Internally Insulated, Zero-Leak, Torsional and Non-Torsional Bellows

• Internal insulation provides low cost alternative to exterior “blanket” methods that can damage exhaust components 
• Features no-leak de-coupler that accommodates all four motions, including torsion
• Works with engine layouts that have exhaust outlets in parallel with crankshaft
• Can be used with engines that demonstrate torsional outputs which create more than 2% displacement at site of exhaust outlet
• Reduces heat loss by up to 88% compared to unlined bellows
• Dampening effect of  internal insulation provides 70% noise reduction over non-insulated systems, enhancing operator comfort
• Reduces static loss, increasing vehicle engine performance and overall fuel efficiency
• Robust, flexible, interlocking interior liner is available in inside diameters ranging from 2.5 to 6 in. (63.5 to 152.4 mm)
• Interior liner is sleeved in an insulation material that is not exposed to external elements or atmospheric conditions that plague external insulation systems
• Internal insulation reduces exposure to superheated exhaust gases to enhance fatigue life 
• Helps vehicles meet 2013 emission standards requiring exhaust systems be leak-free and have heat loss limited to 25 F
