KAN-therm Kolano PP 90 mm 90° plumbing elbow 04104090

KAN-therm Kolano PP 90 mm 90° plumbing elbow is a polypropylene fitting designed to create a right-angle change of direction in PP piping systems. The 90 mm nominal dimension and 90° angle make this elbow suitable for standard drainage and plumbing layouts where compact, corrosion-resistant connections are needed. The product is intended for use in both residential and commercial installations that require reliable flow direction changes in sewage, waste water and non-pressure drainage systems.

Advantages

This PP elbow provides chemical and corrosion resistance inherent to polypropylene, offering long service life in environments where metal fittings would degrade. Its lightweight construction simplifies handling and installation while reducing load on piping supports. The smooth internal surface helps maintain flow characteristics and reduces the risk of deposits. The standardized 90° geometry ensures compatibility with other PP piping components of the same nominal diameter.

Suitable for

• Domestic wastewater and drainage systems
• Commercial sanitary installations
• Underfloor and concealed plumbing runs
• Renovation projects requiring replacement of corroded fittings

Key specifications

• Material: polypropylene (PP)
• Angle: 90°
• Nominal size: 90 mm
• Application: drainage and non-pressure sewage systems
• Surface: smooth internal bore for reduced buildup

How to use

Select the elbow that matches the nominal diameter of the existing PP piping. Prepare mating pipe ends by cutting square, deburring and cleaning to remove dirt and grease. Join the elbow to pipes following the system's recommended joining method for PP components (for example solvent welding, fusion welding or the specified mechanical joint), ensuring proper alignment at 90° and full insertion to the marked depth. Allow any required curing or cooling time before testing the system. Inspect assembled joints for correct fit and leak-tightness prior to covering or concealing the installation.

Usage recommendations

Use compatible PP fittings and follow manufacturer or system-specific joining procedures to ensure reliable connections. Verify that operating temperatures and chemical exposure in the installation are within polypropylene's performance limits. Provide adequate support and spacing to avoid undue stress on the elbow, and perform pressure or leak tests where applicable before putting the system into service.
