Nibco H055400 – Frequently Asked Questions
1) Is the Nibco 907 elbow a DWV fitting or a pressure fitting?
The 907 is a DWV fitting, made for drain, waste and vent lines only. It is not intended for pressure water distribution. If you are running domestic hot and cold supply, you want a pressure-rated wrot copper 90 (the 607 style), not this one. The 907 is built to ASME B16.29, which is the DWV dimensional standard, while pressure copper fittings follow ASME B16.22.
2) What kind of joint does the Nibco 907 90-degree elbow make, and do I need a press tool?
Both ends are solder cups, C x C, so the joint is soldered (or brazed) with a torch. No press tool, no threading, no gaskets. You clean the tube end and the cup, flux both, slip the tube in and heat the joint until solder draws in. For DWV work a 50/50 alternative lead-free solder is standard practice.
3) What pipe sizes does the Nibco 907 DWV elbow come in?
Four sizes: 1-1/4, 1-1/2, 2 and 3 inch. Those are the common DWV runs, 1-1/4 and 1-1/2 for lavatory and fixture arms and vents, 2 inch for showers, tubs and kitchen branch waste, 3 inch for closet bends and main stacks. Both cups on any given fitting are the same size, since it is a straight-size elbow rather than a reducing one.
4) Is a 90-degree copper elbow allowed on a horizontal drain line?
The 907 is a 1/4 bend, a full 90-degree change of direction. Plumbing codes generally restrict a short-pattern 90 to vertical-to-horizontal or vent use; for horizontal-to-horizontal drainage you are normally expected to use a long-turn fitting or a pair of 1/8 bends (45s). Check what your local AHJ enforces before you set it. For vertical drops, stack offsets and vent takeoffs, a 1/4 bend is the usual choice.
5) Can I use the Nibco 907 elbow on a commercial job, or is it residential only?
Both. The 907 is specified for commercial and residential plumbing alike, and it is built to ASME B16.29 for material and workmanship, which is what a spec writer on a commercial DWV drawing will be looking for. Nibco copper fittings are made in an ISO 9001 certified facility.
6) How do I order the right Nibco 907 elbow by part number?
Order by pipe size, and each size carries its own Nibco number: H055250 for 1-1/4 inch, H055300 for 1-1/2 inch, H055400 for 2 inch, and H055550 for 3 inch. There is no handing, no finish and no end-configuration choice to make, since both ends are solder cups of the same size.
7) What alloy is the Nibco 907 wrot elbow made from?
Wrot copper, ASTM B75 alloy C12200, which is the standard DWV copper alloy. It is dezincification resistant, so there is no brass component to lose zinc in aggressive water. That matters more on waste and vent than most people assume, since condensate and sewer gas sit in these lines constantly.
8) Is copper DWV worth using on a green building project instead of plastic?
Copper is reusable at end of life, which is why it keeps showing up on sustainable project specs where recycled content and material recovery score points. The 907 is solid copper, C12200, with no plastic or lining to separate out. It is also a torch joint rather than a solvent weld, so there are no VOC cements on site.
