Advanced Construction - 12-inch-long toilet hose extension with a unique design with one 7/8 male and one 7/8 female end. The female side connects to the ballcock pipe of your toilet tank, while the male side can connect to either a T-adapter for bidets, an existing water supply hose for toilets, or an electric bidet. Versatility - The extension allows T-adapter attachment to be properly fitted to the tank. These accessories are now functional with a skirted toilet seat design, concealed ballcock supply, or if you have limited space or an inaccessible water supply. If the space next to your toilet is tight, or the connection fixtures are hidden, this extension hose connects your T-Adapter or bidet seat. Must-Have Addition - It is a must-have when you have leaking while connecting your T-adapter with the toilet tank, it solves the leaking problem. Secure and Simple Installation - The plastic threads on the female side of the hose install easily, and the special cone washer prevents leaks. The quality build of the parts allows for easy connections to ballcock toilet flush tanks/electric bidet seats. To avoid cross-threading and potential leaking, the design of the plastic threads is precise. You can do it yourself quickly with no complex tools required. 365-Day Money Back Guarantee - If you are not fully satisfied with the hose extension, we will refund your money, no questions asked.
