WAVIN Tee Internal D50/40/87° PP Pipe Fitting

The WAVIN internal tee is a professional-grade polypropylene (PP) pipe fitting engineered for reliable performance in residential and commercial drainage and sewage systems. This component features a precise reduction from 50 mm to 40 mm with an 87-degree branch angle, facilitating efficient wastewater management and secure pipe junctions. Manufactured from high-quality, impact-resistant polypropylene, this fitting offers long-term durability and consistent performance in demanding plumbing environments.

Advantages

This pipe fitting stands out due to its exceptional chemical and thermal resistance, which prevents degradation when exposed to standard household cleaning agents or hot water discharge. The smooth internal surface minimizes the risk of blockages and sediment buildup, ensuring optimal flow rates throughout the drainage network. Its lightweight design simplifies handling and installation, while the robust construction ensures a tight, leak-proof connection that maintains structural integrity over many years of service.

Suitable for

• Residential sewage and greywater drainage systems
• Commercial wastewater plumbing installations
• Connecting pipes of different diameters in internal drainage networks
• Renovation and new construction plumbing projects

When it may not be suitable

This fitting is designed specifically for non-pressure gravity drainage systems and is not suitable for high-pressure water supply lines or industrial chemical transport systems. It should not be used in applications where temperatures consistently exceed the thermal limits of polypropylene.

Key specifications

• Material: Polypropylene (PP)
• Branch diameter: 40 mm
• Main diameter: 50 mm
• Angle: 87 degrees
• Application: Internal drainage and sewage

How to use

To install the fitting, ensure the pipe ends are clean, dry, and free of burrs. Apply a suitable lubricant to the pipe end or the rubber seal within the fitting to facilitate a smooth insertion. Push the pipe firmly into the socket until it reaches the stop point. Ensure the assembly is properly supported by pipe clips to prevent sagging or misalignment during operation.

What to consider before purchase

• Verify the required pipe diameters for your specific drainage layout
• Ensure compatibility with existing pipe materials
• Check local building codes regarding the use of polypropylene fittings
• Confirm the required angle for your plumbing configuration

Usage recommendations

Regularly inspect the drainage system for signs of leaks or blockages. Avoid pouring harsh chemicals or solid waste into the system to maintain the longevity of the polypropylene fittings and the overall plumbing network.
