- 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 bars).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 in to 4 in use toggle link plates and sizes 5 in to 8 in 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.
