Kaczmarek internal sewage elbow PP HT 75×50×90 grey - model 2220222190

Kaczmarek internal sewage elbow PP HT 75×50×90 grey (model 2220222190) is a three-way polypropylene fitting designed for internal wastewater and drainage systems. It connects pipes of different diameters—75 mm, 50 mm and 90 mm—providing a compact junction suitable for both vertical and horizontal routing. The fitting is manufactured from high-temperature (HT) polypropylene material and finished in grey to match standard internal drainage installations.

Advantages

The PP HT construction offers chemical resistance and dimensional stability at elevated temperatures typical for internal sewage applications. Its three-way configuration enables branching between main and secondary pipes without additional adapters, reducing installation time and potential leak points. A smooth internal surface aids flow and reduces the likelihood of blockages, while the grey colour provides visual consistency with common drainage components.

Suitable for

• Internal wastewater discharge and drainage systems
• Connections between pipes of different diameters (75 mm to 50 mm and 90 mm)
• Vertical and horizontal routing in residential and commercial buildings
• Renovation or replacement work where a compact three-way junction is needed

Key specifications

• Material: polypropylene (PP) with high-temperature (HT) properties
• Configuration: three-way elbow fitting
• Pipe diameters: 75 mm main branch, 50 mm secondary branch, 90 mm tertiary branch
• Colour: grey
• Application: internal wastewater and drainage systems

How to use

Verify pipe diameters and routing direction before installation. Prepare the pipe ends by cleaning and deburring to ensure a proper fit. Insert pipes into the appropriate sockets of the fitting following the system’s recommended joining method (e.g., solvent welding, rubber seals or push-fit connection as applicable to the installation system); ensure joints are fully seated and aligned to avoid stress. Check slope and alignment to maintain gravity drainage; perform a leak test after completing the connections.

Usage recommendations

Use the fitting only within indoor sewage and drainage systems and within the temperature and chemical exposure limits specified for PP HT materials. Avoid mechanical damage during handling and provide adequate support for connected pipes to prevent undue loads on the fitting. Follow local plumbing codes and manufacturer guidance for joining methods and testing procedures.
