The "Koma-Susfit" is a mechanical pipe joint that exhibits strong pull-out resistance by expanding the pipe using a dedicated expansion machine. The red and blue FP colors included with the main body allow for easy visual confirmation of any forgotten nut tightening. Even if the installation is completed in a hand-tightened state, the structure is designed to leak during water testing, 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.
