PVC Coupling 3 in. x 4 in. Underground Rated PSI-5

Connect 3-inch Sewer and Drain (S&D) pipe to 4-inch S&D pipe using the S&D Increaser/Reducer Coupling. This coupler also links 3-inch S&D pipe to certain drainage products that are compatible with 4-inch S&D connections, as well as 4-inch S&D pipe to specific drainage products that work with 3-inch S&D connections; these drainage products include channel drain outlets and pop-up emitters. This coupling serves to connect two different diameters of S&D pipe. The Increaser/Reducer Coupling is constructed from polyvinyl chloride (PVC) and creates a Hub X Hub solvent-weld connection. It complies with relevant ASTM standards. It is intended for use in non-pressurized underground sewer and drainage systems, with a maximum working pressure of 5 psi. A hassle-free limited lifetime warranty ensures that the product is free from defects, or it will be replaced. Complimentary tools such as drainage calculators and mobile apps are provided to assist in making your project successful. Established in 1972, the company is a leader in stormwater management solutions, offering reliable products, tools, and support to help you complete your project effectively.
