## Long description

SiGMA-Li KN9025 is a 90° elbow push-fit fitting made of polypropylene (PP) with a 25 mm connection diameter. It is designed to join two pipes at a right angle in plumbing and water distribution systems, offering a tool-free push-fit installation for fast assembly and watertight connections. The fitting is suitable for potable water and common domestic plumbing repairs and installations where a compact, corrosion-resistant elbow is required.
Advantages
The polypropylene construction provides chemical resistance and long service life in wet environments, while the push-fit design allows quick and reliable connections without soldering, gluing or threaded joints. The compact 90° geometry saves installation space and simplifies directional changes in piping runs. The fitting is compatible with standard 25 mm plumbing pipe dimensions and is intended to deliver leak-resistant performance when installed according to recommended procedures.
Suitable for
Hot and cold potable water distribution in residential and commercial buildings
Repair and modification of existing plumbing systems
Tight or confined installation spaces where a compact elbow is needed
Temporary or permanent connections where tool-free assembly is preferred
Key specifications
Material: Polypropylene (PP)
Connection type: Push-fit (push-to-connect)
Angle: 90° elbow
Connection diameter: 25 mm
Application: Plumbing and potable water systems
How to use
Ensure pipe ends are cut square, deburred and free of dirt or burrs before insertion. Mark the insertion depth on the pipe if required. Push the pipe firmly into the fitting until it reaches the internal stop; you should feel resistance and then a secure seating. For disassembly, follow the manufacturer's guidelines for releasing push-fit connections—typically using the appropriate release sleeve or tool to disengage the retention mechanism. Verify the connection by checking alignment and performing a pressure test according to local plumbing regulations.
Usage recommendations
Use the fitting only with compatible 25 mm pipes and in systems within the temperature and pressure limits applicable to polypropylene push-fit fittings. Avoid exposure to direct UV light for prolonged periods and follow local codes for potable water installations. For long-term reliability, inspect joints after initial commissioning and periodically during system maintenance.
