Internal drainage pipe Kaczmarek PP HT 40 x 1.8 x 250 mm grey

Internal drainage pipe Kaczmarek PP HT 40 x 1.8 x 250 mm grey is a rigid polypropylene high-temperature (PP HT) tube designed for internal drainage and wastewater routing inside buildings. The 40 mm nominal diameter, 1.8 mm wall thickness and 250 mm length provide a compact solution for confined spaces, repair works and connection points in building drainage networks. The grey finish is suitable for visible and concealed installations where a neutral appearance and easy handling are required.

Advantages

The polypropylene high-temperature material ensures chemical resistance against common wastewater components and maintains dimensional stability over a wide temperature range. The pipe combines low weight with sufficient rigidity for easy handling and installation in tight spaces. Its consistent wall thickness and smooth inner surface promote reliable flow and reduce the risk of deposits. The short 250 mm length allows precise fitting and simple cutting or joining during renovation and maintenance works.

Suitable for

• Internal wastewater and drainage connections in residential and commercial buildings
• Repair and renovation of existing drainage systems
• Compact installations and confined spaces where short, rigid segments are needed
• Connection pieces between fixtures, traps and larger diameter drains

• Length: 250 mm
• Colour: grey
• Suitable for internal drainage and wastewater use

How to use

Measure and cut the pipe to the required length if necessary, using appropriate tools for plastic pipes to ensure a square, clean edge. Fit the pipe into compatible fittings or couplings designed for 40 mm PP HT systems, following the fitting manufacturer's instructions for solvent, seal or mechanical connections. Ensure joints are aligned and secured; test the assembled section for leaks before closing installation spaces. For renovation jobs, remove any damaged segments and replace with the new 250 mm piece or combine multiple pieces as needed for the layout.

Usage recommendations

Store the pipe away from direct sunlight to avoid long-term UV exposure. Use fittings and seals rated for PP HT systems and verify temperature limits of the overall drainage installation. When joining to other materials, use proper transition fittings and ensure mechanical support to prevent stress at joints.
