Aluminum Cam & Groove Coupler, Female Half, 6 Inch Female NPT

For sizes 5 inch through 8 inch, 75 PSI is the rated working pressure, so that applies directly to this 6 inch coupler. If your application runs at or below that, you're in good shape for liquid transfer. The smaller sizes in this cam and groove lineup are rated at 150 PSI, so if your system demands higher pressure, stepping down in size would be the path forward. Just keep in mind this coupler is not rated for compressed air or steam under any circumstances, regardless of pressure.

Fitting attachment suggestions are listed for each hose in the Hose section of this catalog.

For a 6 inch female NPT connection, this is the female cam and groove coupler with a 6 inch female NPT threaded end, so it matches that thread style and size on the pipe side.
