China PVC Closet Flange Manufacturer, Supplier, Factory

When constructing or renovating a bathroom, the integrity of the toilet installation is paramount. A critical, yet often overlooked, component is the closet flange. Our high-performance PVC Closet Flange is engineered for superior durability and a perfect seal, ensuring a long-lasting, leak-free connection for your toilet. Designed to work seamlessly with modern drainage systems, this flange is compatible with standard PVC Sprinkler Pipe and other common plumbing lines. For those managing project costs, our product offers an excellent balance of quality and Plastic Pipe Price. Unlike some Plastic Conduit Pipe used for electrical applications, our flange is specifically manufactured to handle waste water and resist corrosion. It also provides a reliable solution for retrofitting projects where a connection to older systems is needed, similar to the function of a PVC To Cast Iron Hub. The installation process is straightforward, making it a preferred choice for both professional plumbers and skilled DIYers.


The design of the PVC Closet Flange focuses on long-term performance and ease of installation. Constructed from high-grade, Schedule 40 PVC, this flange exhibits exceptional resistance to chemicals, acids, and alkalis commonly found in household waste systems. Its robust construction prevents cracking and warping, even under significant stress, ensuring the toilet remains securely anchored to the floor. The flange features pre-drilled holes for secure bolting and a deep, reinforced horn that provides a stable base for the wax ring, creating a watertight seal that prevents leaks and potential floor damage. The universal design accommodates all standard 3-inch and 4-inch drainage pipes, offering great versatility for various bathroom layouts.
