Torsional Bellows

Tru-Flex’s BT and BTL bellows meet 2007, 2010, and 2011 EPA regulations for on- and off-road vehicles and equipment requiring that exhaust systems be leakfree from the turbocharger through the treatment system. Available in inside diameters ranging from 2.5 to 5 in (63.5 to 127 mm), BT and BTL designs offer solutions for a no-leak decoupler that will accommodate all four motions, including torsion. An interlocked liner improves durability and reduces static loss and noise, and the thermal-insulation properties eliminate the need for extra insulation. Various end connection styles are available.
