Sewer tee made of polypropylene (PPR) 45 degrees d.110 x d.50 x d.110

The PPR (PP) sewer tee 45° Ø110×Ø50×Ø110 is a transition fitting for indoor drainage systems that allows a neat branch from a Ø110 mm main line to a Ø50 mm pipe at a 45-degree angle. This angle is considered more hydraulically correct than a sharp 90° branch: flow is smoother, turbulence is reduced, and therefore deposit buildup and blockage risk at the junction are lower. For this reason, 45° tees are often chosen for critical sections where stable flow capacity and quieter system operation matter.

The 110/50/110 configuration is ideal when the main stack or horizontal run is Ø110 and the branch needs to be Ø50—for example, when connecting wastewater from a bathtub, shower area, kitchen sink, washing machine (as per the design), or a group of sanitary fixtures. This tee is especially convenient during repairs and remodeling: it allows you to “tap in” an additional branch without complex assemblies or extra adapters, while maintaining clear route geometry and the required slope.

Polypropylene (PPR/PP) is a practical material for drainage systems: it does not rust or corrode, withstands humid environments and domestic wastewater, and keeps its shape and neat appearance over long-term use. The smooth inner surface supports freer flow and reduces contamination buildup, which is particularly important at branching points. The fitting is suitable for household drainage and is designed for typical indoor wastewater temperatures, including occasional hot discharges—up to 95°C.

Installation is quick and convenient: the fitting integrates easily into the pipeline thanks to standard drainage joint geometry (socket/coupling depending on the version) and the use of sealing elements. For a reliable assembly, align the route, keep the seating areas clean, insert the pipe to the installation mark, and avoid misalignment—this ensures a leak-tight and long-lasting joint.

Advantages of the PP 45° tee Ø110×Ø50×Ø110:

smooth 45° branching reduces blockage and deposit risk;

Ø110 to Ø50 transition without extra adapters;

resistant to corrosion, moisture, and household chemicals;

smooth walls for improved flow;

ideal for repairs, upgrades, and non-standard layouts;

suitable for indoor drainage in apartments and private houses.

The PPR 45° sewer tee Ø110×Ø50×Ø110 is an excellent choice when you need a reliable, tidy Ø50 branch while preserving correct drainage operation and strong main-line flow capacity.
