Cast Bronze Fittings are threaded fittings made from which material?

Cast Bronze Fittings are threaded fittings made from which material?

• A. Solder Alloys
• B. ASME B16.15
• C. Threaded fittings made from cast bronze.
• D. ASTM B 32

Answer: (C)

Cast bronze fittings are threaded connections formed from bronze, a copper-based alloy (usually with tin). The term “cast bronze” means the body is created by casting bronze, then the threads are machined to fit standard piping. Bronze provides good corrosion resistance and strength in water-based systems, which is why threaded bronze fittings are commonly specified in sprinkler installations. The other options don’t identify the material. Solder alloys are used for joining copper pipes, not the fitting material themselves. The standard number points to how the fittings are defined or tested, not what they’re made of. ASTM B32 relates to bronze and brass castings in general, not the material of these specific threaded fittings.
