    Grooved one-stop coupling is a type of rigid quick-change pipe fitting. With a unique structural design, it eliminates the need to disassemble bolts, nuts, and gasket during installation. The coupling can be directly inserted into the pipe end and tightened with bolts and nuts.

    Features

    The installation efficiency is more than three times that of standard couplings. The unique structural design prevents the loss of bolts and nuts during the installation process.

    Recommended Applications

    Grooved one-stop coupling is suitable for various types of pipes, such as water supply, drainage, HVAC systems, and other pipelines.
