The Fig. 7401 Rigidlok Coupling from Gruvlok provides a rigid
pipe connection. Rigidity is attained simply; it is designed in.
The Fig. 7401 Rigidlok coupling utilizes a technologically
advanced housing design that conforms to and grips the pipe.
With the Fig. 7401 there emerges a new generation of rigid
Coupling installation is fast and easy, remove only one nut and
swing the housing over the gasket and into the grooves. The
exclusive Guidelok feature automatically separates the grooved
pipe ends and guides the coupling into position as the bolts
are tightened. Precisely sized and oriented tines in the housing
key section firmly grip the pipe. The combination of these
designed in features produce a secure, rigid pipe joint connection.
This coupling is an ideal connector for service and applications
that require a rigid connection.
The Fig. 7401 Rigidlok Coupling is designed for use with roll
grooved or cut grooved standard weight and roll grooved
lightweight pipe, as well as with grooved-end fittings and valves.
The Rigidlok Coupling maintains a rigid connection with
support and hanging in conformance with applicable ANSI
B31.1 Power Piping Code, ANSI B31.9 Building Service Pipe Code
as well as NFPA 13 sprinkler systems.
The Fig. 7401 Rigidlok Coupling allows for working pressure
ratings to 750 psi (51.7 bar) when used on standard wall roll or
cut grooved pipe.
