## Long description

The WAVIN INTER-TEE reducer is a professional-grade polypropylene (PP) fitting engineered for the seamless transition between pipes of different diameters, specifically connecting 50 mm and 40 mm sections. Designed for internal sewage systems, this grey-colored component provides a robust and leak-proof connection, ensuring the integrity of your plumbing infrastructure. Its high-quality construction offers excellent resistance to common household chemicals and temperature fluctuations, making it a reliable choice for both new installations and system repairs.
Advantages
This reducer stands out due to its high-quality polypropylene material, which provides exceptional durability and long-term resistance to corrosion and chemical degradation. The precision-engineered design ensures a tight, secure fit that minimizes the risk of leaks, contributing to a quiet and efficient drainage system. Its lightweight nature and standardized dimensions facilitate quick and easy installation, saving time and effort during plumbing projects. The smooth internal surface helps prevent blockages by ensuring optimal flow characteristics throughout the pipe network.
Suitable for
Connecting 50 mm and 40 mm pipes in internal sewage systems
Residential and commercial drainage installations
Repairing or modifying existing grey-pipe plumbing networks
Gravity-fed waste water management
When it may not be suitable
This component is specifically designed for internal non-pressure sewage systems and should not be used in high-pressure water supply lines or for applications involving temperatures exceeding the thermal limits of polypropylene. It is also not intended for outdoor use where it would be exposed to direct, prolonged UV radiation, as this may degrade the material over time.
Key specifications
Material: Polypropylene (PP)
Color: Grey
Connection diameters: 50 mm to 40 mm
Application: Internal sewage systems
Resistance: Chemical and thermal resistance typical for PP plumbing fittings
How to use
To install the reducer, ensure that the pipe ends are clean, dry, and free of debris. Insert the 50 mm end into the larger pipe and the 40 mm end into the smaller pipe. It is recommended to use a suitable plumbing lubricant on the seals to ensure a smooth insertion and to prevent damage to the gaskets. Push the pipes firmly into the fitting until they are fully seated to guarantee a secure, watertight connection.
What to consider before purchase
Verify the outer diameter of your existing pipes to ensure compatibility with the 50/40 mm sizing
Check local building codes regarding the use of polypropylene fittings in your specific plumbing application
Ensure you have the necessary pipe cutters and lubricants for a professional installation
Usage recommendations
Regularly inspect your plumbing connections for any signs of moisture or leaks, especially after significant changes in water usage or temperature. Ensure that the pipes are properly supported to prevent mechanical stress on the reducer fitting.
