Sewer tee made of polypropylene (PPR) 90 degrees d.110 x d.50 x d.110

The PPR (PP) sewer tee 90° Ø110×Ø50×Ø110 is a transitional T-shaped fitting used to create a right-angle branch from a Ø110 mm main line to a Ø50 mm pipe. It is one of the most common solutions for indoor drainage in apartments, private houses, cottages, offices, and commercial premises—when the main pipeline or stack is Ø110 and a smaller Ø50 line needs to be connected (as per the system design).

A 90° angle is convenient where space is limited: in plumbing shafts, service ducts/boxes, niches, under screed, or in concealed installations. The tee helps form a neat branch and assemble a compact node without extra parts. It is especially often used during repairs and remodeling, when an additional branch must be connected or a new line “picked up,” while keeping a clear, logical route geometry.

The PP drainage tee design is optimized for installation: typically, one end is a socket type, the other a coupling type, and the branch outlet is formed as a coupling. This configuration makes the fitting easy to integrate into the line and allows quick Ø110-to-Ø50 transitioning. The joint is made using standard drainage connection principles (usually a socket joint with a sealing ring, depending on the system), providing leak-tight and reliable performance without glue or complex tools.

The material—polypropylene (PPR/PP)—is ideal for drainage: it does not corrode, withstands humid environments, domestic wastewater, and most detergents. The smooth inner surface reduces dirt adhesion and deposit buildup at the branch area, helping the system maintain flow capacity for longer. Polypropylene fittings are also designed for typical indoor wastewater temperatures, including occasional hot discharges (up to 95°C).

Advantages of the PPR 90° tee Ø110×Ø50×Ø110:

Ø110 to Ø50 transition in a single part—fewer joints and easier installation;

90° branching for compact indoor routing;

polypropylene body: durable, corrosion-free, moisture- and chemical-resistant;

smooth walls reduce deposit and blockage risk;

suitable for repairs, upgrades, and non-standard remodeling.

The PPR 90° sewer tee Ø110×Ø50×Ø110 is a practical choice for a reliable branch from a 110 mm main line to a 50 mm line when leak-tightness, installation convenience, and stable drainage performance are essential.
