Low leakage polypropylene (PPR) branching 45 degrees d.50 x d.40 x d.50

The PPR (PP) sewer tee 45° Ø50×Ø40×Ø50 is a transitional fitting for indoor drainage systems, designed to create a neat branch from a Ø50 mm pipe to a Ø40 mm pipe at a 45-degree angle. This angle is considered one of the best options for gravity drainage: wastewater flows more smoothly, turbulence is reduced, and therefore the risk of deposits and blockages at the junction is lower. Compared to sharp 90° branches, a 45° tee helps maintain gentler hydraulics, which is especially important in sections used daily and under varying loads.

The 50/40/50 configuration is commonly used in drainage layouts for apartments, private houses, cottages, and commercial facilities. It is convenient when the main line is Ø50 (often used for kitchen and sanitary drains) while the branch needs to be Ø40—for example, for specific fixtures or auxiliary branches (according to the design). This tee enables a technically correct connection without unnecessary couplers or reducers, reduces the number of joints, and makes the node more compact and tidy—particularly in niches, service ducts/boxes, and hard-to-access areas.

The fitting is made of polypropylene (PPR/PP), one of the most practical materials for drainage: it does not corrode, withstands humid environments, and resists domestic wastewater and most detergents. Polypropylene fittings retain their shape and geometry over time, and the smooth inner surface reduces dirt adhesion. This is critical at branching points, where deposits most often form if hydraulics are poor or turns are too abrupt. The product is also suitable for occasional hot discharges—its material is designed for typical indoor drainage temperatures (up to 95°C).

Installation is quick and requires no complex tools. Standard drainage joint geometry (socket/coupling depending on the version) ensures easy pipe connection. For a reliable installation, simply: align the run, maintain the required slope, clean the seating areas, check the seal (if applicable), and insert the pipe to the installation mark without misalignment. The result is a secure, leak-tight joint that remains serviceable for maintenance if needed.

Advantages of the PP 45° tee Ø50×Ø40×Ø50:

smooth 45° branching reduces deposit and blockage risk;

Ø50 to Ø40 transition without extra connectors;

resistant to corrosion, moisture, and household chemicals;

smooth walls for improved flow capacity;

compact and convenient for tight spaces;

suitable for repairs, upgrades, and remodeling.

The PPR 45° sewer tee Ø50×Ø40×Ø50 is an optimal solution for neatly connecting a Ø40 line to a Ø50 main run while preserving correct system operation, stable flow, and long-lasting joints.
