TUBE FLEX and EGR Pipe are the two automotive parts we take the most pride in offering:
TUBE FLEX absorbs vehicle noise from engine vibration, for a better living environment. From its place between the engine and muffler, this unique pipe fills the in-cabin environment with a mood of tranquil luxury by absorbing the vibration noises of the idling engine.
The EGR Pipe, a device installed inside the engine, cleans exhaust gas by circulating incomplete combustion gas back to the engine compartment. The demand for the EGR Pipe is expected to grow as controls on CO2, NOX, and other exhaust gas emissions become more rigorous in the months and years ahead.

TUBE FLEX absorbs engine vibration in three axes, enabling automakers to design engines with optimal features for a comfortable and quiet cabin space. TUBE FLEX helps meet the requirements of automakers.

TUBE FLEX is made up of two layers, each with a thickness of only 0.25 mm. This design makes it possible for even a short part to absorb expansion, compaction, and vibration. The five-layer structure includes an outer pipe for both fire-prevention and insulation against excessive thermal emission from inside to out. Safety, needless to say, is guaranteed. Our engineers have realized an integrated production system covering every step from prototyping to mass production, including the processes for production equipment and fixtures. We meet quality, delivery, and cost requirements to satisfy our customers’ wishes.

A special jig for small-radius bending of thin tubes at our manufacturing line allows us to significantly downsize the main body of the pipe. This, in turn, reduces the size of engine compartments and improves vehicle mileage.

Unique and advanced forming techniques such as hydroforming and bulging allow us to save space and simplify joint structures for much easier assembly. The ease of assembly will further strengthen the position of EGR Pipe, a product already at the center of attention for its advantages in emission control.
