What is the minimum thickness for brass water closet flanges?

The minimum thickness for brass water closet flanges is established at 0.125 inches. This specification is important for ensuring that the flange is sturdy enough to support the toilet and withstand the forces exerted during use, such as weight and pressure from water flow. A flange that meets or exceeds this thickness will help prevent bending or breaking, which can lead to leaks and other plumbing issues.

In plumbing standards, materials such as brass are chosen not only for their durability and resistance to corrosion but also for their specific applications. The specified thickness is critical as it contributes to the integrity and longevity of the plumbing installation, ensuring that the connections remain watertight and secure over time.
