Alkotest KN9020 elbow connector 90° Fi20 for drainage/pipe systems

Alkotest KN9020 elbow connector 90° Fi20 is a compact plastic fitting designed to join two 20 mm nominal-diameter pipes at a right angle. Intended for drainage and small-diameter plumbing systems, this elbow provides a reliable directional change in tight routing situations. It is suitable for repair, replacement or new installations in residential and light commercial piping where Fi20 connections are specified.

Advantages

The 90° design ensures a clean angular change while maintaining internal flow for small-diameter drain runs. Manufactured from durable plastic, the connector resists corrosion and common chemical exposure found in drainage applications. Its compact form factor makes it suitable for confined spaces and allows straightforward integration with Fi20 pipe systems. The fitting is lightweight and easy to handle during installation or maintenance.

Подходит для

• Прокладки и ремонта малых дренажных линий диаметром Fi20
• Смены или замены участков трубопровода в жилых и малоэтажных коммерческих зданиях
• Поворота трассы трубопровода в ограниченном пространстве

Key specifications

• Angle: 90° elbow for directional change
• Nominal diameter: Fi20 (20 mm)
• Material: durable plastic suitable for drainage use
• Connection type: push-fit or solvent-weld compatible depending on system (verify compatibility with pipe type)
• Application: drainage and small-diameter plumbing systems

How to use

Ensure pipes to be joined are cut square and free of burrs or debris. Dry-fit the elbow to confirm alignment and required cut lengths. Prepare mating pipe surfaces according to the pipe system’s instruction (cleaning, priming or applying adhesive if required). Insert pipes into the elbow until fully seated and secure following the chosen joining method. After assembly, check the connection for alignment and test the drain run for leaks by running water through the system.

Usage recommendations

Use this fitting only with compatible Fi20 pipe materials and joining methods specified by the pipe manufacturer. Avoid excessive mechanical stress at the joint and allow any adhesive or solvent connections to cure fully before applying flow or load. For installations in exposed or load-bearing conditions, consult system guidelines to ensure correct support and spacing of pipe runs.
