The "Koma-Susfit" is a mechanical pipe fitting that exhibits strong pull-out resistance by expanding the pipe using a dedicated expansion machine. The included red and blue FP colors allow for easy visual confirmation of whether the nut has been tightened. In the unlikely event that the installation is completed in a hand-tightened state, the structure is designed to leak during a water test, making it easier to identify any problematic areas early on. 【Features】 ■ Strong connection through pipe expansion ■ Easy pipe expansion work ■ Quick and reliable connection ■ Easy visual confirmation of forgotten tightening with red and blue FP colors *For more details, please refer to the PDF materials or feel free to contact us.
