Nibco H030250 – Frequently Asked Questions

1) What does the Nibco 904 DWV male adapter connect between?
It takes a copper DWV solder cup on one end and a male NPT thread on the other, so you can go from soldered copper drain pipe into a threaded female connection like a trap adapter, cleanout, or threaded fitting on a fixture drain. The end configuration is C x M (NPT).
2) Can the Nibco 904 adapter be used on a pressure water line, or is it drain only?
Drain, waste and vent only. It is a DWV fitting made to ASME B16.29, which is the thinner-wall copper drainage standard, not a pressure fitting standard. For supply piping you want a pressure-rated wrot copper male adapter instead.
3) What sizes does the Nibco 904 DWV male adapter come in?
Two: a 1-1/4 inch (MPN H030250) and a 1-1/4 x 1-1/2 inch reducing/increasing version (MPN H030350). The second is the one to grab when your copper DWV stub is one size and the threaded side needs to be the other.
4) Is the Nibco 904 adapter cast brass or wrot copper?
Wrot copper, ASTM B75 alloy C12200. That is the same base material as the DWV tube it solders to, so there is no dissimilar metal issue at the solder joint, and the fitting is listed as dezincification resistant.
5) Is this adapter approved for commercial work or just residential?
Both. Nibco lists the 904 DWV male adapter for commercial and residential plumbing systems, and it is built to ASME B16.29 for material and workmanship.
6) Do I need thread sealant on the male NPT end of a Nibco 904 DWV adapter?
The threaded end is a standard male NPT taper, so it seals on the threads and takes pipe dope or PTFE tape like any NPT joint. The other end is a solder cup, so plan the sequence: sweat the copper side first and let it cool before you torque the threaded side, since heat travels through the fitting.
