Pipe fitting MAGNAPLAST Trójnik UDBEA 87° DN 110/50 – pipe tee 87-degree, DN110 to DN50

MAGNAPLAST Trójnik UDBEA 87° DN 110/50 is a single-piece pipe tee designed to join a DN110 main run with a DN50 branch at an 87-degree angle. The fitting is intended for drainage and sewer applications where a near-right-angle diversion is needed between pipes of different diameters. Its geometry supports secure connection and alignment in gravity or low-pressure waste systems.

Advantages

The tee provides a compact solution for adapting between DN110 and DN50 pipework with a minimal change in flow direction due to its 87° branch angle. Manufactured to fit common drainage systems, it simplifies installation by eliminating the need for multiple adapters or separate reducing pieces. The one-piece construction reduces potential leak points and maintains consistent internal flow paths between inlet and branch.

Suitable for

• Gravity drainage lines in residential and commercial buildings
• Sewer connections requiring a near-right-angle branch
• Retrofit projects where DN110 must be reduced to DN50
• Underground and above-ground waste installations compatible with DN110 and DN50

Key specifications

• Branch angle: 87 degrees between main and branch
• Main pipe connection diameter: DN110
• Branch connection diameter: DN50
• Single-piece tee design suitable for drainage systems
• Intended for gravity or low-pressure waste and sewer applications

How to use

Position the MAGNAPLAST Trójnik UDBEA so the DN110 spigot or socket aligns with the existing main line and the DN50 outlet faces the intended branch direction. Prepare mating pipe ends by cleaning and, if required by the pipe material, applying the appropriate lubricant or sealant compatible with the system. Insert and seat each connection fully according to the pipe manufacturer’s fitting instructions to ensure proper engagement and sealing. Support the assembly as required and check alignment before backfilling or commissioning the drainage run.

Usage recommendations

Use compatible DN110 and DN50 pipes and seals rated for drainage or sewer service. Verify local codes for minimum slope and installation practices for gravity drainage. Avoid exposing the fitting to sustained internal pressure beyond gravity flow conditions unless explicitly approved by the pipe system specifications.
