The sealing ring solves the problem of the smelly smell at the connection between the drain pipe under the bathroom sink and kitchen sink and the drain pipe of the washing machine and the sewer!
The soft silicone material is suitable for hoses with a diameter of 3-6 cm. It is anti-odor, anti-mouse and anti-fly. The gap between the sewer pipe and PVC drain pipe can be easily fixed. The diameter is 30mm, the outside is 65mm, and the inner ring has screw holes!
