Flexible Conduit Coupling for Hazardous Locations

This Appleton Century Crofts coupling connects 1/2 inch FNPT to 1/2 inch MNPT conduit in hazardous areas. It is built with a bronze body and brass core for durability. The fitting suits Class I, II and III locations where vibration or movement is a concern. It is not for buyers who need a rigid, non-flexible connection.

Multi-Angle Installation with NPT Threads

The coupling installs by threading the female and male NPT ends into compatible IMC or RMC conduit. Its multi-angle design allows alignment without precise orientation. Over-tightening can damage the bronze threads, so hand-tighten plus a slight turn is advised. It is not for installers who cannot access both conduit ends.

13 1/16 Inch Overall Length Decides Fit

The overall length of 13 1/16 inches determines whether the coupling fits inside the available enclosure space. This single measurement governs clearance in tight panels or junction boxes. Verify the dimension against your layout before ordering. It is not for projects where a shorter or longer flexible section is required.

Questions about this item

How can I verify the coupling is installed correctly after setup?

Check that the 1/2 in FNPT and 1/2 in MNPT ends thread securely into the conduit and fitting, the 13 1/16 in overall length matches the specification, and the bronze body with brass core shows no gaps at the multi-angle connection.

What comes in the box and what must be purchased separately?

The package contains the hazardous-location flexible coupling with natural-finish bronze housing and brass core, 8 in flex length, 1/2 in FNPT x 1/2 in MNPT ends; conduit, fittings and thread sealant are not included.

Which version should I choose for a 1/2 in trade-size conduit system?

Select this 1/2 in trade-size coupling rated Class I Div 1/2 Groups A-D, Class II Div 1/2 Groups E-G and Class III, designed for IMC or RMC conduit where vibration or movement requires a multi-angle connection.
