The 90-degree elbow features a solder cup, male solder end, and a long turn radius. The fitting provides a means of changing the pipeline direction 90 degrees. Please refer to NIBCO technical data sheets and catalogs for engineering and installation information. In addition to its inherent qualities of beauty, durability and low maintenance, copper's reusability makes it an ideal application in sustainable projects. NIBCO® copper fittings are manufactured in an ISO 9001 certified facility, and backed by a 50-year limited warranty. Because of its longstanding reputation for innovation and precision in design and manufacturing, NIBCO is the preferred brand in the industry.

Nibco 9080600 – Frequently Asked Questions
1) What does Ftg x C mean on the Nibco 607-2-LT elbow, and which end goes where?
Ftg x C means one end is a male fitting end (sized to slip inside a solder cup, same as the outside of copper tube) and the other is a female solder cup that receives tube or another fitting end. On the 607-2-LT you use it when you need to come straight out of another fitting's cup without adding a stub of tube. Both ends are solder joints, so the whole connection is sweated with solder, not threaded or pressed.
2) Is the Nibco 607-2-LT elbow approved for potable water?
Yes. The 607-2-LT wrot copper elbow is lead-free and certified to NSF/ANSI/CAN 61 and 372, which are the drinking water standards inspectors look for on potable systems. It is also dezincification resistant. That covers both residential and commercial plumbing use.
3) Can this copper elbow be used on a medical gas line?
It is built to meet NFPA 99 Health Care Facilities Gas and Vacuum Systems and Compressed Gas Association Pamphlet G4.1 for medical gas, and med-gas is listed among its system uses. For a hospital or clinic install, that is the compliance line an inspector checks. Note that med-gas brazing is a separate qualification from ordinary plumbing sweat work, and the fitting has to be handled to the cleanliness requirements of that system.
4) What sizes does the Nibco 607-2-LT long radius elbow come in?
Thirteen sizes, from 1/8 inch up through 3 inch: 1/8, 1/4, 3/8, 1/2, 5/8, 3/4, 1, 1-1/4, 1-1/2, 2, 2-1/2 and 3 inch, plus one reducing configuration at 1/2 x 3/8 inch. The small end of that range (1/8 through 5/8) is where refrigeration and ACR work lives; 1/2 through 2 inch covers most domestic water and hydronic branch runs. Order by pipe size, not by the fitting's own dimensions.
5) Can I solder a Ftg x C elbow straight into a valve or another fitting's socket?
Yes, that is the point of the Ftg end. The male end is dimensioned to enter a solder socket directly, so the elbow can be sweated into a valve cup, a coupling or a tee without cutting a short piece of tube to bridge them. The C end still takes tube in the normal way. In tight mechanical rooms that saves a joint and an inch or two of run.
6) Why choose a long radius copper 90 elbow instead of a standard short radius one?
The long turn radius on the 607-2-LT sweeps the direction change over a wider arc instead of turning it tight. That is what you want where flow noise, turbulence, or pressure drop matters, and on refrigeration and ACR lines where a gentler bend keeps oil and refrigerant moving. The tradeoff is space: a long radius 90 takes up more room in the wall or ceiling than a short radius fitting, so in tight framing the standard 90 is the one that fits.
7) What material and standards does the Nibco 607-2-LT wrot copper elbow meet?
It is wrot copper, ASTM B75 alloy C12200. Material and workmanship follow ASME B16.22, and material, workmanship and dimensions follow MSS SP-104. Select diameters are UL 207 Recognized to 700 PSI. Manufacturing is in an ISO 9001 certified facility. Those are the callouts a spec engineer or institutional buyer needs on the submittal.
8) Is there a reducing version of this long radius 90 elbow?
One reducing size is offered, 1/2 inch by 3/8 inch, Nibco part 9080200. Every other size in the range is a straight same-size 90. If you need to step down at the turn on a size combination other than 1/2 to 3/8, you will need a separate reducer or coupling ahead of the elbow.
9) Which Nibco part number do I order for a 3/4 inch long radius Ftg x C 90 elbow?
3/4 inch is Nibco part 9080400. For reference across the common trade sizes: 1/2 inch is 9080250, 1 inch is 9080600, 1-1/4 inch is 9080700, 1-1/2 inch is 9080800 and 2 inch is 9080850. Give the size and that number and there is no ambiguity with the short radius version.
10) Will this elbow work on a hydronic heating or chilled water loop, or is it potable only?
Not potable only. The 607-2-LT is rated across commercial and residential plumbing, heating, HVAC, chilled and industrial systems, compressed air, fire protection and irrigation. Same fitting, same solder joint, in all of them. Lead-free certification just means it also clears potable duty, it does not restrict it to potable work.
11) Can I press this fitting or does it have to be soldered?
It has to be soldered or brazed. Both ends are solder connections, a cup on one side and a male fitting end on the other, with no sealing element and no press bead. If your crew is running a press system, this elbow is not a substitute for a press fitting on that run. On the other hand, it goes onto standard copper tube with ordinary flux and solder and no proprietary tool.
12) Does a 1/4 bend mean the same thing as a 90 degree elbow?
Same fitting. 1/4 bend is the older plumbing term for a quarter turn, which is 90 degrees, and the 607-2-LT is listed both ways. If a drawing calls out a 1/4 bend copper elbow, this is what it is asking for. The LT in the model designation is the long turn radius, which is the part that distinguishes it from a standard 90.
13) Is copper a good choice for a LEED or sustainable building spec?
Copper carries well on sustainability submittals because it is fully reusable at end of life, and Nibco calls that out for this fitting alongside its durability and low maintenance. Combined with the lead-free construction and NSF/ANSI/CAN 61 and 372 certification, it is the material distributors serving green building projects tend to stock over the alternatives.
