The FIG 7003 HingeLok Coupling is specially designed for applications requiring a quick connection and/or disconnection of a pipe joint. The hingelok coupling is ideal for those applications where frequent pipe removal is required for maintenance or any other reason. It provides for system working pressure ratings up to 300 psi (20.7 bar). The coupling halves are permanently hinged to provide an assembly that eases handling & installation 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.
Recommended for water service, diluted acids, alkalies solutions, oil-free air and many other chemical services. For hot water applications the use of Gruvlok Extreme Temperature lubricant is recommended. NSF-61 Certified for cold and hot water applications up through 12 in.
NOT FOR USE IN PETROLEUM APPLICATIONS.
