Sewer tee made of polypropylene (PPR) 90 degrees d.75 x d.50 x d.75

The PPR (PP) sewer tee 90° Ø75×Ø50×Ø75 is a transitional T-shaped fitting designed to create a right-angle branch from a Ø75 mm pipeline to a Ø50 mm pipe. It is used in indoor drainage systems for apartments, private houses, cottages, offices, and commercial premises when the layout requires connecting a smaller Ø50 line to a Ø75 main run while keeping the joint compact and installation-friendly.

Ø75 is often used as a “reinforced” line on sections where increased wastewater volume may occur (for example, when combining multiple drains or running a shared branch line—according to the design). Ø50, in turn, is one of the most common diameters for connections from sanitary fixtures and local drainage runs. The 75/50/75 configuration makes the transition neat and logical: instead of a chain of reducers and adapters, you use one fitting—reducing the number of joints and potential leak points, and simplifying future maintenance.

A 90° branch is chosen when the plan and limited space require a strictly perpendicular tie-in: in plumbing shafts, niches, service ducts/boxes, concealed routing, or tight bathroom areas. This tee is especially useful during repairs and remodeling, when you need to quickly connect a new Ø50 line, “pick up” an additional drain, or re-route part of the system without fully dismantling the main line.

The fitting is made of polypropylene (PPR/PP), which is ideal for drainage due to its resistance to operating conditions: it does not corrode, withstands humid environments, domestic wastewater, and most detergents. Polypropylene requires no painting, retains its shape, and keeps a neat appearance over long-term use. A key drainage advantage is the smooth inner surface, which supports freer flow and reduces dirt adhesion—particularly important at transitions and branching points.

The tee design supports easy assembly: drainage fittings typically combine socket and coupling sections, with leak-tightness provided by a sealing element (depending on the version). Installation requires no complex tools: prepare the pipes, clean the seating areas, check the seal, insert to the installation mark, and avoid misalignment. With proper slope and correct branch orientation, the tee ensures stable operation and reduces the likelihood of issues at the junction.

Advantages of the PPR 90° tee Ø75×Ø50×Ø75:

Ø75 → Ø50 transition in one part—fewer joints and faster installation;

90° branching for compact indoor routing;

polypropylene body: durable, corrosion-free, resistant to moisture and household chemicals;

smooth walls reduce deposit buildup and blockage risk;

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

The PPR 90° sewer tee Ø75×Ø50×Ø75 is a practical solution for reliably connecting a Ø50 line to a Ø75 main run when leak-tightness, a clean routing scheme, and stable indoor drainage performance are essential.
