The Fig. 7401 RigidLOK Coupling utilizes a technologically advanced housing design that conforms to and grips the pipe. 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. The Figure 7401 RigidLOK Coupling with a Pre-Lubricated Grade “E” EPDM, Type “A” gasket (coupling is easily identified by purple nuts) is intended for use in fire protection systems installed in accordance with NFPA Standard 13 “Sprinkler Systems.”
