Pipe connector Alkotest ZZ2534 G threaded M/F 25×3/4 for PP-N pipes

Alkotest ZZ2534 G threaded M/F 25×3/4 is a pipe connector for polypropylene (PP-N) piping systems. It provides a secure mechanical transition between a 25 mm PP-N pipe and a 3/4-inch threaded fitting, enabling connection to valves, taps, pumps or other threaded components used in plumbing, water supply and heating installations. The design supports a sealed joint between plastic pipe and metal or plastic threaded parts while maintaining flow continuity.

Advantages

The connector combines a push-in or fusion-compatible body for PP-N pipe with a standard 3/4" threaded end, enabling straightforward adaptation between plastic piping and threaded hardware. Its construction ensures reliable sealing and mechanical stability under typical domestic and light-commercial conditions. The component is compact, requires minimal installation space and is suitable for confined areas where a threaded transition is needed.

Suitable for

• Connecting 25 mm PP-N pipes to 3/4" threaded valves and fittings
• Plumbing and potable water distribution in residential and small commercial systems
• Heating circuits where a threaded interface to radiators or pumps is required
• Repair and modification of existing pipe runs that use mixed plastic and threaded components

Key specifications

• Material compatibility: polypropylene (PP-N) pipe to threaded fittings
• Pipe side size: 25 mm nominal (for 25× PP-N pipe)
• Thread type and size: 3/4 inch male/female threaded interface
• Connection form: mechanical threaded transition between pipe and fitting
• Application areas: plumbing, potable water, heating installations

How to use

Prepare the 25 mm PP-N pipe by cutting squarely and deburring the end. Depending on the connector design, insert and secure the pipe by the recommended joining method for PP-N (for example, socket fusion, electrofusion or push-fit where applicable) to ensure a sealed connection. Thread the 3/4" counterpart onto the connector's threaded end using appropriate sealing tape or thread sealant if required by the installation standards. Tighten to the torque recommended for the mating fitting material to avoid over-stressing the plastic components.

Usage recommendations

Use compatible joining methods and follow local plumbing codes for potable water or heating systems. Verify pressure and temperature limits of the overall system and ensure thread sealing materials are suitable for potable water if required. Inspect the assembled joint for leaks after initial pressurization and periodically during operation.
