Hose adapter fitting "NNT"

Reduction of contamination troubles! The rise in oil temperature is mitigated, ensuring longer oil life.

We would like to introduce our hose adapter fitting "NNT." Due to its R-shaped flow path, turbulence (cavitation) is suppressed, which reduces piping vibrations. Additionally, the significant reduction in fluid resistance helps lower oil temperature rise, contributing to the longevity of the oil. Furthermore, since the flow path is formed through plastic processing rather than traditional cutting, contamination does not occur. 【Features】 ■ Contributes to the longevity of the fluid (oil) used ■ Helps reduce piping vibration noise ■ Reduces contamination issues *For more details, please refer to the PDF document or feel free to contact us.

Fluid fitting

It can be started with just one standard motor and operated at the motor's maximum torque.

Our company offers "fluid couplings" that enable energy-saving startup with soft start. We have types with couplings, pulleys, flanges, and those that can be directly mounted on internal combustion engines, as well as large variable-speed fluid couplings that control the enclosed oil and can manage rotation speed and torque. Additionally, since power is transmitted through the enclosed oil, it absorbs shock loads and torsional vibrations during operation, significantly extending the lifespan of machines such as chains and belts, making it economical. 【Features】 ■ Soft start ■ Overload protection (torque limiter) ■ Absorbs shocks and vibrations *For more details, please download the PDF or feel free to contact us.
