Sanitas PPR Brass Coupling 34.2525, 25mm x 3/4 inch Female Thread

The Sanitas PPR Brass Coupling 34.2525 is a professional-grade plumbing component engineered for seamless transitions between PPR piping systems and threaded metal fittings. This coupling features a 25mm diameter connection for PPR pipes on one side and a 3/4 inch female thread on the other, providing a robust and leak-proof interface for various water supply and heating applications.

Advantages

The primary benefit of this coupling is its high-quality construction, which combines the thermal stability of PPR with the mechanical strength of brass. The brass threaded insert is designed to withstand significant pressure and temperature fluctuations, ensuring long-term reliability in demanding plumbing environments. Its corrosion-resistant properties prevent degradation over time, making it an ideal choice for both residential and commercial infrastructure projects where durability is essential.

Suitable for

• Connecting PPR pipes to threaded metal valves or faucets
• Plumbing installations in residential heating systems
• Potable water supply networks
• Industrial fluid transport systems requiring transition fittings

This coupling may not be suitable for high-pressure steam lines or systems involving aggressive chemicals that could react with brass or the specific grade of PPR material used. It is also not intended for use with non-standard pipe diameters or threads that do not match the specified 25mm and 3/4 inch dimensions.

Key specifications

• Pipe diameter: 25mm
• Thread type: 3/4 inch female thread
• Material: PPR and brass
• Application: Plumbing and heating systems

To install the coupling, first ensure the PPR pipe end is clean and properly cut. Use a standard PPR welding machine to fuse the 25mm side of the coupling to the pipe according to the manufacturer's temperature and timing guidelines. Once the weld has cooled and solidified, the threaded side can be connected to the corresponding 3/4 inch male fitting using appropriate sealing materials like PTFE tape or liquid thread sealant to ensure a watertight connection.

What to consider before purchase

• Verify that your existing pipe system is compatible with 25mm PPR standards
• Ensure the mating component features a standard 3/4 inch male thread
• Check the pressure and temperature ratings of your system against the fitting specifications
• Confirm that you have the necessary tools for PPR welding

Always perform a pressure test on the completed installation before concealing the pipes behind walls or flooring to ensure all joints are secure and leak-free.
