## Summary description

THERMAFLEX Kolano PE 15/9 elbow fitting (3526-009015-030) is a polyethylene piping component designed to connect and change direction between PE pipes with nominal dimensions 15 mm and 9 mm. It serves plumbing and low-pressure fluid distribution systems, enabling compact 90° directional transitions. Suitable for repair, extension or branching of polyethylene lines in residential and light-commercial installations.

## Long description

THERMAFLEX Kolano PE 15/9 elbow fitting (model 3526-009015-030) is a polyethylene connector designed to join and change direction between PE pipes with nominal diameters of 15 mm and 9 mm. It creates a compact 90° bend for low-pressure fluid distribution systems, enabling repair, extension or branching of polyethylene lines in residential and light-commercial installations. The fitting is intended for use with compatible PE tubing and provides a straight-forward mechanical connection where a change of pipe diameter and direction is required.
Advantages
The polyethylene construction offers corrosion resistance, chemical inertness and flexibility appropriate for potable water and irrigation circuits within its pressure rating. Its compact 90° geometry allows space-saving installation in tight sections while maintaining a smooth internal profile to minimize flow disruption. The fitting is lightweight, simple to handle and suitable for quick replacement or retrofitting in existing polyethylene piping runs.
Suitable for
Repairing damaged sections of PE piping in household water supply and irrigation systems
Extending polyethylene lines where a diameter transition from 15 mm to 9 mm is needed
Creating compact 90° turns in low-pressure distribution and drainage layouts
Retrofit and small commercial installations with polyethylene tubing
Key specifications
Material: polyethylene (PE)
Connection configuration: 90° elbow joining 15 mm to 9 mm nominal PE pipe
Application pressure: suitable for low-pressure fluid distribution systems (follow system specifications)
Typical uses: potable water, irrigation, and other non-pressurized or low-pressure fluid lines
Design: compact 90° bend to minimize space requirements
How to use
Ensure both PE pipes are compatible in wall type and nominal dimension before installation. Prepare pipe ends by cutting square and deburring. Push the 15 mm and 9 mm PE pipes fully into the respective ends of the elbow fitting according to the manufacturer's insertion depth recommendations; secure connections by the appropriate method for the fitting and system (for example, push-fit, compression or heat-fusion techniques if applicable to the specific variant). Verify alignment and ensure the elbow forms the intended 90° direction change. After installation, perform a pressure test of the section according to local regulations and system requirements.
Usage recommendations
Use the elbow fitting only within the intended pressure and temperature limits of the polyethylene piping system. Match pipe wall type (e.g., PE100, PE80) and installation method to ensure long-term performance. Avoid exposure to direct UV without appropriate protection and prevent mechanical loads or impacts at the joint during and after installation.
