## Long description

The SiGMA-Li KWW1612 wall elbow fitting is a 90° polypropylene (PP) connector with BOR Plus surface treatment, engineered for joining 16 mm plastic pipe to a 1/2" threaded fixture. Designed for compact angled transitions in plumbing systems, this fitting provides a sealed connection between plastic tubing and threaded valves, taps or appliances. The polypropylene construction offers resistance to corrosion and common domestic water conditions, while the BOR Plus treatment improves surface quality and durability for reliable performance in water distribution installations.
Advantages
The fitting combines a compact 90° design with lightweight PP material, ensuring easy installation in confined spaces without adding significant weight. The BOR Plus treatment enhances the durability of the connector and its resistance to wear and deposits. The threaded 1/2" receptacle provides a standard interface for many valves and fixtures, while the 16 mm connection side is compatible with common plastic tubing systems used in domestic and light commercial water supply.
Suitable for
Connecting 16 mm plastic pipes to 1/2" threaded faucets, valves or appliances
Compact angled transitions in household water supply and distribution
Light commercial plumbing where corrosion-resistant plastic fittings are preferred
Installations requiring a neat, space-saving 90° connection to a wall-mounted fixture
Key specifications
Material: polypropylene (PP) with BOR Plus surface treatment
Connection A: 16 mm push-fit / socket for plastic tubing
Connection B: 1/2" threaded female connection
Angle: 90° elbow
Typical use: cold and warm water distribution (non-pressurized appliance interfaces depend on system design)
Design: compact wall elbow for space-limited installations
How to use
Prepare the 16 mm plastic pipe by cutting squarely and deburring the end. Insert the pipe into the 16 mm side until it seats firmly according to the pipe system's fitting instructions. Apply appropriate thread sealant or PTFE tape to the 1/2" male thread of the fixture, then engage the fitting's 1/2" female thread and hand-tighten before final wrench-tightening as required; avoid excessive torque to prevent damage to the polypropylene body. Ensure the installation follows local plumbing codes and pressure ratings of the overall system.
Usage recommendations
Use this SiGMA-Li wall elbow in indoor cold and warm water distribution systems where plastic fittings are suitable. Avoid exposure to direct UV or continuous high-temperature conditions beyond the material's rated limits. For secure threaded joints, use compatible sealant or tape and check for leaks after pressure testing the system.
