Features
This type of exhaust flexible pipe with interlock has an interlock liner inside, as well as one layer of stainless steel wire braids and another layer of wire meshes outside. It is a highly flexible metal hose designed to fit all common exhaust system pipe diameters.
Isolate vibration generated by the engine; thereby relieving stress on the exhaust system.
Reduce premature cracking of manifolds and downpipes and help extend the life of other components.
Compensate for the misalignment of exhaust pipes.
Applicable to different positions of an exhaust system, and the most effective when installed in front of the pipe section of the exhaust system.
Absorbs muffler Pipe thermal expansion.
Double wall stainless steel for ensuring durability.
Made of high temperature resistant & highly corrosion resistant material.
Available in full sizes & of any stainless steel material.
This type flexible pipes mainly used for OEM or OES market needs.
Quality Control
Every single unit is tested at least twice throughout the manufacturing cycle The first test is a visual inspection. The operator makes sure that:
The part is placed in its fixture to ensure proper fitment on the vehicle.
The welds are completed without any holes or gaps.
The ends of the pipes are fished to the proper specifications.
The second test is a pressure test. The operator blocks all of the entrances and exits of the part and fills it with compressed air with a pressure equal to five times that of a standard exhaust system. This guarantees the structural integrity of the welds holding the piece together.
