## Long description

SiGMA-Li ZZ321 PP 32 mm (1") for piping systems is a polypropylene (PP) connector designed to join sections of 32 mm nominal-diameter piping. The fitting is intended for plumbing and fluid transport applications where a thermoplastic, corrosion-resistant connection is required. Its dimensions match standard 32 mm pipes and it is suitable for installations in residential and light commercial systems that use PP components.
Advantages
The connector is made of polypropylene, which provides chemical resistance to common water and non-aggressive fluid media and reduces the risk of corrosion compared with metallic fittings. Its standardized 32 mm (1") nominal size ensures compatibility with corresponding PP pipes and simplifies installation. The lightweight construction facilitates handling and positioning during assembly while maintaining mechanical strength appropriate for typical domestic and light commercial pressure ranges.
Suitable for
Domestic cold and warm water distribution systems
Connection of 32 mm polypropylene piping runs
Light commercial plumbing and fluid transport applications
Indoor installations where corrosion-resistant plastic fittings are preferred
Key specifications
Material: polypropylene (PP)
Nominal diameter: 32 mm (1")
Application: piping connector for plumbing and fluid transport
Compatibility: designed for use with 32 mm PP pipes

How to use
Prepare the pipe ends by ensuring they are clean, cut square, and free of burrs or debris. Push the pipe ends into the connector until a firm fit is achieved according to the installation practice for polypropylene fittings.
