What materials can cleanout plugs be made of?

Cleanout plugs are essential components in plumbing systems, designed to provide access to the drainage system for cleaning and maintenance purposes. The materials used for these plugs must be durable and resistant to the conditions they will face in a plumbing environment.

Brass is commonly used for cleanout plugs because it is strong, resistant to corrosion, and has good mechanical properties, making it ideal for applications in drainage systems where contact with water and various substances is likely. Plastic is another appropriate material, as it is lightweight, resistant to corrosion, and cost-effective. In many cases, plastic options are also designed to withstand common chemicals found in residential and commercial drainage systems.

Other materials, like steel and aluminum, may not be ideal for cleanout plugs due to issues related to corrosion over time. Rubber and glass, while useful in certain applications, do not provide the necessary strength or chemical resistance for cleanout plugs. Similarly, while ceramic and composite materials have their applications, they do not generally meet the requirements for the structural integrity and longevity expected from cleanout plugs. Hence, brass and plastic stand out as the most suitable materials according to plumbing codes and practices.
