1-1/2 Inch DWV Bronze Adapter

The Nibco 802 is a cast bronze drain-waste-vent adapter sized for 1-1/2 inch tube and pipe. It connects a copper tube end to a male NPT thread in residential or light commercial plumbing systems. The fitting is rated for temperatures from -20 to 400 degrees Fahrenheit. It meets ASME B16.23 standards for material and dimensions.

Copper-to-Male-NPT Connection Type

The single specification that determines fit is the C x MNPT connection: one sweat end for 1-1/2 inch copper tube and one male pipe thread of the same nominal size. The outside diameter measures 1-5/8 by 1-1/2 inches. Maximum working pressure is 577 psi at 200 degrees Fahrenheit. Verify that the mating female thread matches NPT taper and that the tube is Type K, L, or M copper.

Straightforward Sweat-and-Thread Install

Installation requires cleaning the tube, applying flux, and sweating the cup end with lead-free solder before engaging the male threads with appropriate sealant. Common issues include overheating the bronze and damaging the threads, or using pipe dope on the sweat joint instead of flux. Ensure the system is depressurised and cooled before starting work. The fitting is new and ready for immediate use.

Questions about this item

What does the 577 psi @ 200 °F rating mean for everyday drainage use?

It shows the cast-bronze body can handle far more pressure than any residential DWV system produces, so the joint will not fail from normal waste-line surges.

How does the C x MNPT connection work with standard 1-1/2 in piping?

The copper-tube end slips over 1-1/2 in Type K, L or M tube for soldering, while the male NPT threads screw into a matching female-threaded fitting or adapter.

What clearance is needed to install the 1-5/8 in outside-diameter fitting?

Allow enough space for a torch to reach the solder cup and for a wrench to engage the hex on the threaded end; the body measures 1-5/8 in across at its widest point.
