Product identity

The Banjo CPLG150 is a polypropylene coupling designed for drain and trap assemblies in plumbing systems. It connects two 1-1/2 inch FNPT threaded pipes in a straight run. The fitting is rated for a maximum operating pressure of 150 psi.

Critical specification

The fitting uses Schedule 80 polypropylene construction with FNPT x FNPT threads. This determines compatibility with matching Schedule 80 pipe and threaded components. The pressure rating of 150 psi and temperature range of -20 to 150 degrees F define its safe operating envelope.

Fit and alternatives

This coupling suits installers joining two female-threaded Schedule 80 polypropylene pipes of the same diameter. It is not for buyers who need a different pipe size, a slip connection, a higher pressure rating above 150 psi, or a material other than polypropylene.

Questions about this item

How does the 150 psi rating hold up once the coupling is installed in a real plumbing system?

The coupling is rated for a maximum working pressure of 150 psi. When installed correctly with compatible Schedule 80 pipe and proper thread sealant, it will maintain that pressure limit within the stated temperature range of -20 to 150 degrees Fahrenheit.

What does the FNPT x FNPT connection type mean for compatibility with other fittings?

FNPT stands for Female National Pipe Taper threads on both ends. This means the coupling accepts male NPT threaded pipe or nipples of the same 1-1/2 inch nominal size, creating a sealed joint when tightened with thread tape or pipe dope.

What physical space and pipe size are needed to fit this Schedule 80 coupling?

The coupling fits 1-1/2 inch nominal pipe size and is built to Schedule 80 wall thickness. You will need matching Schedule 80 male-threaded pipe or nipples and enough clearance to thread both ends fully into the coupling body.
