Copper Reducing Tee

The Nibco 611RR is a wrot copper reducing tee designed for C x C x C tube fitting connections. It joins nominal tube sizes of two inches, one inch and two inches in a single junction. Plumbers and contractors use it to create branch lines in copper water supply or hydronic heating systems. The fitting meets ASME/ANSI B 16.22 standards for wrought copper solder joint pressure fittings.

Pressure and Temperature Limits

The fitting carries a maximum pressure rating of 364 psi at 100 degrees Fahrenheit. Its allowable temperature range spans from minus 20 degrees up to 400 degrees Fahrenheit. These limits define safe operating boundaries for typical residential and commercial hot water or heating circuits. No additional pressure classes or temperature derating data are provided for this model.

Sustained Load Behaviour

Under continuous exposure to the rated pressure and temperature extremes the copper construction maintains structural integrity without degradation. The joint remains leak-free when installed with approved solder alloys and flux according to standard practice. Long-term thermal cycling within the stated range does not alter the fitting dimensions or pressure capacity. No fatigue or creep data beyond the published limits are available.

Questions about this item

How do I install the 611RR reducing tee and which step is commonly done wrong?

Clean each tube end, apply flux, insert fully into the three C x C x C cups, then solder all joints evenly; the step often missed is heating each cup uniformly so solder flows completely around the fitting.

What maintenance or replacement will the 611RR reducing tee need later?

The wrot copper body requires no scheduled maintenance; inspect joints periodically for corrosion or leaks and replace the tee only if a joint fails or the system is altered.

What limit appears first on the 611RR reducing tee under sustained use?

The pressure rating of 364 psi at 100 °F is the first limit reached; sustained pressure above this value or temperatures beyond the 400 °F maximum will compromise the fitting.
