    Product Information



    Korea's first UL approved Loop Flexible Joint - U type & V type


    Certificate: UL, FM


    The purpose of installing Loop Flexible Joints is to protect fire and other piping in buildings from shocks generated by seismic load or ground subsidence in the event of earthquakes, thereby preventing direct damages, fire, explosion, and other disasters and reducing damages arising therefrom.

    In comparison to loops or bellows made of solid pipes, they require less anchor load and smaller space for installation.


    Youngjin Loop Flexible Joint is designed to move in all directions hence suitable for various applications,especially fire sprinkler systems.

    1) Simple structure, excellent expansion compensation properties

    2) Smaller spatial requirements for the same level of expansion

    3) Easy piping alignment and multiple pipe arrangements for efficient space use

    4) Lightweight for easy installation

    5) Almost no thrust force from piping, hence reductions in anchor and support installation costs

    6) Excellent soundness against exciting force

    7) Omnidirectional absorption: absorbs seismic displacement in six directions
