  • The Fig. 7003 Hingelok Coupling is specially designed for
    applications requiring a quick connection and/or disconnection
    of a pipe joint. The Fig. 7003 Hingelok Coupling is ideal for those
    applications where frequent pipe removal is required for
    maintenance or any other reason. Fig. 7003 Hingelok Coupling
    provides for system working pressure ratings up to 300 psi (20.7 bar).
  • The Fig. 7003 Hingelok Coupling halves are permanently hinged
    to provide an assembly that eases handling and installation.
    The two coupling halves are hinged for ease of handling and
    are secured by a cam-action handle. Sizes 1" to 4" use toggle
    link plates and sizes 5" to 8" use a toggle bolt to attach the
    cam-action handle to the housings. The cam-action locking
    handle permits rapid installation without the need for
    additional tools and maintains secure closure of the coupling
    into the pipe grooves. Final assembly of the locking pin to the
    Hingelok Coupling adds an extra measure of security required
    in critical pipe joint applications.
