The wrot copper heat exchanger slips entirely through the fitting on the small end of the run, and exhibits good corrosion-resistance properties. Sizes available are the same as listed for the NIBCO® 611 tee, where the tee has one or more reductions on one end of run. 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.
