Wall Elbow Fitting SiGMA-Li KWW2512, 25 mm (1/2"), 90° PP for Plumbing

SiGMA-Li wall elbow fitting KWW2512 is a 90° polypropylene (PP) fitting designed for 25 mm (1/2") plumbing systems. It provides a compact right-angle connection between a wall outlet and horizontal or vertical piping runs. Manufactured from corrosion-resistant PP, the fitting is suitable for potable water and general plumbing installations where reliable, low-maintenance performance is required.

Advantages

The polypropylene construction ensures resistance to corrosion, chemicals and scaling while remaining lightweight for easy handling. A precise 90° angle supports space-saving layouts and neat transitions at wall outlets. The fitting is compatible with standard 25 mm plastic plumbing systems, enabling straightforward integration and reduced installation time. Its smooth internal surfaces promote good flow characteristics and minimize pressure loss.

Suitable for

• Domestic potable water supply lines using 25 mm pipework
• Bathroom and kitchen wall outlet connections
• General plumbing and service risers in residential buildings
• Renovation projects replacing metal elbows with plastic fittings

Key specifications

• Material: polypropylene (PP)
• Angle: 90 degrees
• Connection size: 25 mm (1/2")
• Application: potable water and general plumbing
• Design: compact wall elbow for outlet-to-pipe transition

How to use

Prepare compatible 25 mm piping and wall outlet points, ensuring clean, square pipe ends. Assemble the elbow according to the connection method used in the system (push-fit, solvent weld, or fusion) following the pipe manufacturer’s instructions. Position the fitting so the 90° turn aligns with the intended direction of the run, then secure the joint and test the system for leaks at working pressure. Ensure accessibility for any required future maintenance.

Usage recommendations

Verify compatibility with the specific 25 mm piping system and follow local plumbing codes. Avoid exposing polypropylene fittings to direct flame or solvent conditions outside recommended installation methods. Pressure-test the installation after assembly and perform periodic inspections for mechanical stress or displacement.
