The main benefit of the 20 cm connection tube is the sealing and security it provides in sanitary basin installations. With this product, your installation is more resistant and guarantees that water will not leak. Developed to be applied in all models of toilets that have horizontal water inlet, the tube connects the toilet bowl to the water installation behind the wall, in a simple and easy way without requiring any type of equipment. It is the perfect fit that ensures water enters your basin safely. In addition, it has a length closer to the standard distance to reduce material waste at the time of installation.
