Alkotest ZW2534 connector, female thread 3/4" to pipe Ø25 mm (PP)

The Alkotest ZW2534 connector is a polypropylene (PP) fitting designed to join a 25 mm outer-diameter PP pipe to a 3/4" (G) female threaded fitting. It provides a transition between a smooth-bore PP pipeline and a standard threaded plumbing connection, intended for water supply and general plumbing installations. When fitted correctly, the connector creates a mechanical and sealed joint compatible with typical household and light-commercial plumbing systems.

Advantages

The PP construction offers chemical resistance and corrosion-free performance in potable water and non-aggressive fluid systems. The combination of a socket for a 25 mm pipe and a female 3/4" thread simplifies transitions without the need for additional adapters. The connector is lightweight, dimensionally stable, and suitable for use in systems where a reliable threaded interface is required.

Suitable for

• Connecting 25 mm polypropylene pipes to 3/4" threaded fittings in water supply networks
• Domestic and light-commercial plumbing repairs and modifications
• Projects requiring a sealed transition from PP piping to threaded valves, taps or meters

Key specifications

• Material: polypropylene (PP)
• Pipe connection: socket for outer-diameter 25 mm pipe
• Threaded end: female 3/4" (G) thread
• Application: cold and treated water supply, general plumbing
• Connection type: mechanical socket joint to pipe and threaded coupling to fittings

How to use

Prepare the 25 mm PP pipe by cutting a clean, square end and deburring the inner and outer edges. Insert the pipe into the connector socket until it seats fully; use the appropriate joining method for PP pipes (heat fusion or approved adhesive/solvent recommended by system specifications) or a compatible mechanical compression sleeve if applicable. Apply suitable sealing tape or thread sealant to the male 3/4" thread before engaging the threaded mating part, and tighten to the torque recommended for the mating fitting to avoid deformation. Verify alignment and perform a pressure check according to relevant installation standards.

Usage recommendations

Use the connector in systems operating within the temperature and pressure limits suitable for polypropylene components. Avoid exposure to aggressive chemicals and direct UV for prolonged periods. Follow local plumbing codes and manufacturer guidance for jointing methods and pressure testing to ensure a durable, leak-free installation.
