Which material should fittings be made of when used with copper pipes?

Fittings used with copper pipes should be made of brass due to its compatibility with copper in terms of thermal expansion, corrosion resistance, and mechanical strength. Brass, which is an alloy of copper and zinc, shares similar properties with copper, allowing for a strong bond and minimizing the risk of galvanic corrosion, which can occur when dissimilar metals are connected. This compatibility is crucial for maintaining the integrity of plumbing systems and ensuring long-lasting connections.

Brass fittings are also able to withstand high pressure and temperature changes without deforming, making them ideal for various applications in plumbing. They provide a reliable and leak-proof connection when used with copper pipes, ensuring efficient flow and minimal maintenance over time. Furthermore, brass is less prone to corroding than some other materials, ensuring durability in a wide range of conditions typically found in plumbing environments.
