Elbow fitting 45° SiGMA-Li BOR Plus K4520, polypropylene (PP), 20 mm

SiGMA-Li BOR Plus K4520 is a 45° elbow fitting made from polypropylene (PP) with a 20 mm nominal diameter, intended for creating angular pipe connections in plumbing systems. The fitting is suitable for potable water and general hydraulic installations where PP components are used, offering a corrosion-resistant joint and compatibility with common PP pipe assemblies.

Advantages

The polypropylene construction ensures chemical and corrosion resistance while keeping the component lightweight. The 45° angle allows smoother directional changes than a 90° elbow, reducing flow turbulence and pressure loss in many applications. The 20 mm nominal size fits standard small-diameter PP piping, enabling straightforward integration into existing systems and simplified assembly during installation.

Suitable for

• Potable water distribution in residential and commercial buildings
• General plumbing and sanitary installations using PP pipes
• Space-limited routing where a 45° directional change is required
• Repair and retrofit work on small-diameter plastic piping

Key specifications

• Material: polypropylene (PP)
• Angle: 45° elbow
• Nominal diameter: 20 mm
• Application: potable water and general plumbing systems
• Connection type: compatible with standard PP pipe joining methods
• Corrosion resistance: suitable for water and common non-aggressive media

How to use

Prepare pipe ends by cutting square and deburring internal and external edges. Ensure mating pipe surfaces and the fitting are clean and free of contaminants. Assemble the fitting to the PP pipe following the chosen joining method appropriate for PP components (e.g., push-fit, solvent or thermal joining where applicable). Confirm correct alignment at 45° and allow any required setting or cooling time per the pipe system's joining recommendations before applying pressure or filling the system.

Usage recommendations

Use the fitting within the temperature and pressure limits specified for polypropylene piping systems. Avoid exposure to aggressive chemicals beyond typical potable water and household fluids. For long-term performance, follow manufacturer guidelines for joint type, installation torque (if applicable), and system testing after assembly.
