Elbow fitting 45° KAN-therm Kolano 45 PP 25 mm

The KAN-therm Kolano 45 PP 25 mm is a 45-degree elbow fitting made of polypropylene (PP) designed for pipe systems with a 25 mm nominal diameter. It provides a compact direction change in plumbing, heating and general fluid conveyance installations where corrosion resistance and low weight are required. The fitting is compatible with systems that use polypropylene components and is intended for use with potable water and heating circuits when a 25 mm PP elbow is specified.

Advantages

This polypropylene elbow offers chemical and corrosion resistance, low thermal conductivity and a lightweight construction that simplifies handling and installation. Its molded shape ensures a smooth internal flow path to reduce pressure loss at the bend. The material is durable under typical operating conditions of potable water and heating systems, and the 45° angle provides a gentler directional change compared with a 90° elbow, which can improve flow characteristics in some installations.

Suitable for

• Plumbing installations transporting potable water with 25 mm piping
• Residential and commercial heating circuits using polypropylene pipework
• General fluid conveyance and recirculation lines where a 45° directional change is needed
• Replacement or repair of existing PP-based pipe runs with 25 mm diameter

Key specifications

• Material: polypropylene (PP)
• Angle: 45 degrees
• Nominal diameter: 25 mm
• Connection type: socket/insert for compatible 25 mm PP pipe systems
• Typical applications: potable water, heating circuits, general fluid conveyance

How to use

Prepare pipe ends by cutting square and deburring to ensure full insertion into the fitting sockets. Confirm compatibility of the 25 mm polypropylene pipe and the installation method (e.g., heat fusion, solvent welding, or push-fit) appropriate for the specific system and local standards. Insert the prepared pipe ends into the elbow sockets to the recommended depth and complete the chosen joining method. After assembly, check alignment and secure adjacent piping as required to avoid mechanical stress on the joint; then pressurize the system and inspect for leaks following the applicable testing procedure.

Usage recommendations

Use with pipes and joining methods recommended for polypropylene to ensure reliable, long-term performance. Avoid exposing the fitting to temperatures and pressures outside the limits specified by the overall PP piping system design. When in doubt, consult system documentation or a qualified installer for correct fusion or connection techniques.
