Pipe connector SiGMA-Li ZZ2534 25 mm (3/4") PP

PP pipe connector SiGMA-Li ZZ2534 for 25 mm (3/4") piping is a mechanical coupling made from polypropylene (PP) designed for joining compatible plastic pipes in water supply and irrigation systems. The fitting creates a straightforward butt or slip connection that is suitable for low-pressure fluid transport in domestic plumbing, garden irrigation, and similar installations where chemical resistance and lightweight materials are required.

Advantages

This polypropylene connector offers chemical and corrosion resistance typical of PP materials, a lightweight design that simplifies handling and installation, and dimensional stability for consistent alignment of 25 mm (3/4") pipes. The part is suitable for repeated use in non-pressurized or low-pressure systems and resists common contaminants found in irrigation and potable water distribution when PP is an appropriate material choice.

Suitable for

• Domestic cold-water supply lines using 25 mm (3/4") plastic pipes
• Garden and landscape irrigation systems
• Low-pressure fluid transport and recirculation circuits
• Temporary or modular plastic pipe assemblies

Key specifications

• Material: polypropylene (PP)
• Nominal pipe size: 25 mm (3/4")
• Type: mechanical pipe connector / coupling for plastic pipes
• Typical applications: water supply, irrigation, low-pressure fluid lines
• Operating pressure: suitable for low-pressure systems (follow system design limits)

How to use

Prepare pipe ends by cutting squarely and removing burrs or debris. Ensure pipe outside diameter matches the connector nominal size. Insert pipe fully into the connector according to the connection method recommended for the system (push-fit, solvent-weld, or mechanical closure as applicable for PP fittings). Verify alignment and, if required by the installation type, secure the joint with appropriate clamps or joining technique. After assembly, test the system at a controlled pressure to confirm leak-free operation before putting the installation into regular use.

Usage recommendations

Use this PP connector in systems designed for polypropylene fittings and within the temperature and pressure limits of PP materials. Avoid exposure to solvents or conditions that can degrade polypropylene. Verify compatibility with the fluid transported and follow local plumbing codes and best practices for installation and testing.
