The Harvey 4375 is a wax ring designed for toilet installation on 3 inch and 4 inch waste lines. Plumbers and contractors rely on wax rings to create a watertight seal between the base of a toilet and the floor flange. This seal prevents sewer gases and wastewater from escaping at the connection point. A properly installed wax ring is one of the most critical steps in any toilet installation or replacement job. The Harvey 4375 includes a wax horn that extends into the drain opening to direct waste flow and improve the seal. The horn fits both 3 inch and 4 inch waste lines, making this ring suitable for most standard residential and light commercial toilet installations. The kit includes all the hardware needed to complete the job. Two 1/4 inch by 3.5 inch solid brass bolts are included along with plastic retainers, round washers, and nuts. Solid brass bolts resist corrosion from moisture and cleaning products, which helps maintain the integrity of the connection over time. Having all the necessary hardware in one package saves time on the job site. Plumbers do not need to source bolts and retainers separately. The wax material conforms to irregular surfaces during installation, filling small gaps and creating a consistent seal under the weight of the toilet. This ring is a go-to component for toilet resets, new rough-in installations, and bathroom renovation projects. It is compatible with most standard two-piece and one-piece toilets. The Harvey 4375 is a reliable, straightforward solution for professional plumbing installations requiring a durable wax seal and complete bolt kit.
The Harvey 4375 wax ring with horn provides a complete toilet sealing solution for 3 inch and 4 inch waste lines, including all mounting hardware needed for a professional installation.
