SiGMA-Li plumbing elbow 90° PP 20 mm (3/4") BOR Plus model KW2034

SiGMA-Li plumbing elbow 90° PP 20 mm (3/4") BOR Plus model KW2034 is a polypropylene right-angle fitting engineered for 20 mm (3/4") pipe connections. The fitting provides a compact and reliable 90° change of direction for piping systems. Its BOR Plus treatment enhances surface properties and chemical resistance, making it suitable for potable water and general plumbing applications where a durable PP elbow is required.

Advantages

The polypropylene construction ensures corrosion resistance and low weight while maintaining dimensional stability. BOR Plus surface treatment improves resistance to scaling and some chemicals, extends service life in contact with potable water, and facilitates smoother flow at the elbow. The 20 mm (3/4") connection size is compatible with common piping in residential and light commercial installations, and the 90° geometry allows space-efficient routing of lines.

Suitable for

• Potable water distribution in residential plumbing systems
• General water supply and circulation lines in light commercial buildings
• Connections where a compact 90° directional change is required
• Replaceable sections in plastic piping networks

Key specifications

• Material: polypropylene (PP) with BOR Plus surface treatment
• Connection size: 20 mm (3/4")
• Angle: 90° elbow
• Typical applications: potable water and general plumbing
• Weight: lightweight thermoplastic construction for easy handling

How to use

Prepare pipe ends according to the piping system requirements (cut square, deburr, and clean). Install the elbow by following the manufacturer's recommended joining method for polypropylene fittings used in your system—this may include solvent welding, mechanical insertion, or fusion depending on the pipe and connector type. Ensure proper alignment to maintain the 90° direction and check joints for secure sealing. After installation, perform a pressure test of the section in line with local plumbing codes and standards.

Usage recommendations

Use this polypropylene elbow in systems within the temperature and pressure ratings of PP materials; avoid exposure to aggressive solvents or sustained temperatures beyond the material specification. For potable water installations, follow sanitary installation practices and relevant local regulations. Verify compatibility of joining technique with BOR Plus treated surfaces to ensure reliable long-term performance.
