## Long description

PP Connector SiGMA-Li ZZ2012 20 mm (1/2") polypropylene plumbing fitting is a compact coupling designed to join PP pipes in potable water and heating systems. The fitting is made from polypropylene, offering chemical resistance and a corrosion-free alternative to metal connectors. Its 20 mm (1/2") connection size suits common domestic piping runs and light commercial installations where a lightweight, durable plastic coupling is required.
Advantages
The polypropylene construction provides resistance to many chemicals and prevents rust or galvanic corrosion typical of metal parts. The connector's low weight simplifies handling and installation while reducing load on pipe runs and supports. Thermal stability within the product's rated range ensures reliable performance in cold and hot water circuits, and the smooth internal surface minimizes flow resistance and scaling. The fitting is compatible with standard 20 mm (1/2") PP pipe systems and enables secure, leak-resistant joints when installed according to recommended techniques.
Suitable for
 Domestic potable water supply lines
 Residential heating circuits and underfloor heating manifolds
 Light commercial plumbing installations
 Repair and modification of existing polypropylene piping
Key specifications
 Material: Polypropylene (PP)
 Connection size: 20 mm (1/2")
 Application: Water supply and heating systems
 Corrosion resistance: Yes — non-metallic construction
 Weight: Low — lightweight plastic construction
 Internal surface: Smooth to reduce flow resistance
How to use
Prepare pipe ends by cutting squarely and removing burrs or debris. Ensure both pipe and connector surfaces are clean and dry before joining. Depending on system requirements and local practice, use the appropriate joining method for polypropylene fittings—such as solvent welding, heat fusion, or push-fit if the specific connector variant supports it—following manufacturer-recommended temperatures, times and tools. After assembly, allow any required cooling or curing time before pressurizing the system and perform a pressure test to verify joint integrity.
Usage recommendations
Use this PP connector within the temperature and pressure ranges appropriate for polypropylene plumbing systems; avoid exposure to aggressive solvents outside PP compatibility. Store fittings away from direct sunlight to limit UV degradation and follow industry best practices for support spacing and thermal expansion allowances in piping layouts.
