Caulking ferrules for sanitary drainage must be made of what material?

Caulking ferrules for sanitary drainage are typically made from a copper alloy due to its excellent properties that make it ideal for plumbing applications. Copper is resistant to corrosion, which is crucial in sanitary drainage systems where moisture and chemicals are present. The durability and strength of copper allow for a reliable and secure connection, minimizing the risk of leaks.

Moreover, copper can withstand temperature fluctuations and has good thermal conductivity. Its malleability also enables it to form a tight seal when caulked with the surrounding material, ensuring the integrity of the drainage system.

In contrast, steel alloys are more prone to rust and corrosion when exposed to water, while plastic may not provide the same level of structural support and durability needed for long-term drainage applications. Brass, while also corrosion-resistant, is less common compared to copper alloys in this specific use case. Therefore, the properties of copper alloy make it the preferred material for caulking ferrules in sanitary drainage systems.
