KAN-therm coupling with internal thread 25x1/2" PP, model 04103125

The KAN-therm coupling with internal thread 25x1/2" PP (polypropylene) is designed to join 25 mm plastic piping to a 1/2" threaded fitting. Manufactured from polypropylene, the coupling offers a lightweight and corrosion-resistant transition between plastic pipelines and metal or plastic threaded components. The product is intended for installations where a secure female thread connection is required and where PP material properties—chemical resistance, low thermal conductivity and dimensional stability—are desirable.

Advantages

This KAN-therm coupling provides a compact and reliable mechanical connection between a 25 mm PP pipe and a 1/2" threaded fitting without the need for fusion or adhesive at the thread interface. Its polypropylene construction reduces susceptibility to corrosion and scaling while keeping the fitting lightweight. The internal thread allows straightforward assembly with standard 1/2" male threaded components and ensures a consistent sealing surface when used with appropriate sealing materials. The coupling’s dimensions and design support standard installation practices in domestic and commercial plumbing systems.

Suitable for

• Connecting 25 mm polypropylene pipeline to 1/2" threaded valves, taps or fittings
• Domestic and commercial potable water systems compatible with PP components
• Heating circuits where PP fittings are specified and a threaded transition is required
• Utility installations such as distribution manifolds and service connections

Key specifications

• Material: Polypropylene (PP)
• Pipe connection size: 25 mm
• Thread type: Internal female thread equivalent to 1/2"
• Function: Transition coupling between plastic pipe and threaded fitting
• Typical applications: Water supply, heating, utility connections

How to use

Prepare the 25 mm PP pipe by cutting squarely and deburring the end to ensure a smooth insertion. Insert the pipe into the coupling using the recommended joining method for the KAN-therm PP system (for example, mechanical joint or compatible socket technique as required by the specific installation). Engage the 1/2" male threaded component into the internal thread and apply an appropriate thread sealant (such as PTFE tape or approved anaerobic sealant) if a threaded metal or plastic fitting is being connected. Tighten to the torque appropriate for the mating component, avoiding excessive force that could deform the polypropylene thread.

Usage recommendations

Use this coupling in systems designed for polypropylene fittings and ensure temperature and pressure limits of the overall installation are compatible with PP material. When connecting to metal fittings, select thread sealants suitable for potable water where required and follow manufacturer guidance for allowable torque values to prevent damage to the internal thread.
