Nonmetallic fittings are typically made from which materials?

Explanation:
Nonmetallic fittings are designed to work with nonmetallic piping, which in many low-rise residential sprinkler systems is plastic (such as PVC or CPVC). Plastic fittings are molded to fit these pipes and are favored because they provide corrosion resistance, lightweight handling, and easier, cost-effective installation through solvent-weld or similar joints. Metals like steel, brass, or aluminum are used with metallic piping, so they aren’t considered nonmetallic fittings in this context.
