MAGNAPLAST Kolano UdBB 50/67 plumbing elbow 146325

MAGNAPLAST Kolano UdBB 50/67 plumbing elbow 146325 is a purpose-built plastic elbow for creating a sealed change of direction and size transition between pipes with 50 mm and 67 mm diameters. Designed for wastewater and drainage systems, the fitting ensures a reliable connection where a reduction or enlargement between these two pipe sizes is required. The product is intended for use in both new installations and repair work in residential and commercial plumbing systems.

Advantages

The elbow provides a controlled and sealed directional change while accommodating two different pipe diameters without the need for additional adapters. Its molded construction reduces the risk of leaks and simplifies installation compared with multiple-piece transition assemblies. The design supports standard drainage system layouts and facilitates smooth flow between connected pipes.

Suitable for

• Connection between 50 mm and 67 mm wastewater or drainage pipes
• Residential bathroom and kitchen drainage systems
• Commercial and light-industrial drainage applications
• Repair or retrofit work where size transition and directional change are required

Key specifications

• Material: corrosion-resistant plastic (polymer)
• Connection diameters: 50 mm and 67 mm
• Type: plumbing elbow with size transition
• Sealing method: integrated socket/joint design for sealed connection
• Application: wastewater and drainage systems

How to use

Ensure both pipe ends are clean, free of debris, and cut squarely. Insert the smaller and larger pipe ends into the corresponding sockets of the elbow until seated according to the manufacturer’s depth marks or fit tolerance. Apply any required lubricant or sealing compound recommended for the pipe system material to assist insertion and achieve a watertight joint. Support the connected pipes to avoid strain on the fitting and verify alignment and gradient for proper drainage before finalizing the installation.

Usage recommendations

Use the elbow in gravity drainage systems only; avoid applying excessive mechanical load or torque during installation. Check compatibility with the specific pipe material and local building codes. Perform a pressure or water-tightness test after installation to confirm a sealed connection.
