Alkotest KN4520 elbow pipe connector 45° for Ø20 mm

Alkotest KN4520 elbow pipe connector 45° for Ø20 mm is a compact plastic fitting designed to create a fixed 45-degree change of direction in pipelines with a 20 mm outer diameter. Intended for simple and reliable joining of plastic pipe runs, this elbow assists in redirecting fluid flow in domestic and light commercial plumbing and fluid-handling systems where a precise angular deviation is required.

Advantages

This 45° elbow connector provides a stable and space-saving method to alter pipe direction without the need for custom bending. Made for compatibility with Ø20 mm plastic pipes, it simplifies installation by offering a consistent angle and a secure joint. Its compact profile reduces intrusion into installation zones, and the standardized shape supports predictable flow behavior and easy replacement when system modifications are needed.

Suitable for

• Redirecting water supply lines in domestic plumbing for Ø20 mm pipes
• Light commercial fluid-handling systems requiring compact directional changes
• Repairing or modifying existing plastic pipe runs with a fixed 45° angle
• Tight installation spaces where gradual directional adjustment is preferable to sharp angles

Key specifications

• Connector angle: 45°
• Compatible pipe outer diameter: 20 mm
• Material: plastic construction suitable for standard plumbing use
• Form factor: compact elbow fitting for inline installation

How to use

Prepare pipe ends by ensuring they are clean, cut square, and free of burrs. Insert the Ø20 mm pipe ends into each side of the elbow fitting until seated according to the chosen joining method (push-fit, solvent weld, or adhesive as appropriate for the pipe and fitting materials). Ensure proper alignment to achieve the intended 45° deviation, then secure the joint following standard installation practice for the pipe system being used. After assembly, verify the connection for leaks and mechanical stability before returning the system to service.

Usage recommendations

Use compatible joining methods and adhesives rated for the pipe material, follow local plumbing codes, and avoid excessive mechanical loads at the fitting. For pressurized systems, conduct pressure testing after installation to confirm leak-free performance.
