Sanitas 33.2525 PPR Brass Coupling D25 x 3/4 inch Male Thread

The Sanitas 33.2525 PPR Brass Coupling is a professional-grade plumbing component engineered to facilitate a seamless transition between PPR piping systems and threaded metal fittings. With a nominal diameter of 25 mm and a 3/4 inch male thread, this coupling provides a robust and reliable connection point for various water supply and heating applications. The integration of high-quality brass with durable PPR material ensures long-term stability and performance in demanding plumbing environments.

Advantages

This coupling stands out due to its superior material composition, which combines the chemical resistance of PPR with the mechanical strength of brass. The design minimizes the risk of leaks at transition points, providing a secure seal that withstands pressure variations and thermal expansion. Its corrosion-resistant properties make it suitable for both hot and cold water systems, ensuring longevity and reducing the need for frequent maintenance in complex piping infrastructures.

Suitable for

• Connecting PPR pipes to threaded valves or pumps
• Residential and commercial water supply installations
• Heating system piping transitions
• Renovation of existing plumbing networks

When it may not be suitable

This fitting is not intended for use in high-pressure steam systems or industrial applications involving aggressive chemicals that may degrade the PPR material. It is also not compatible with piping systems that do not utilize standard metric PPR dimensions or standard BSP threaded connections.

Key specifications

• Material: PPR and high-quality brass
• Connection type: PPR socket to male thread
• Nominal diameter: 25 mm
• Thread size: 3/4 inch male
• Application: Hot and cold water plumbing

How to use

To install the coupling, first ensure the PPR pipe end is cut square and cleaned of any burrs. Use a professional PPR welding machine to heat the socket end of the coupling and the corresponding pipe simultaneously according to the manufacturer's temperature and timing guidelines. Once heated, insert the pipe into the coupling socket and allow it to cool undisturbed to form a permanent, leak-proof bond. The threaded side can then be connected to the corresponding female fitting using appropriate thread sealant, such as PTFE tape or liquid sealant, to ensure a watertight seal.

What to consider before purchase

• Verify the outer diameter of your existing PPR piping
• Check that the threaded component has a matching 3/4 inch female connection
• Ensure you have the correct PPR welding equipment available
• Confirm the system pressure and temperature ratings match your installation requirements

Usage recommendations

Always use professional-grade thread sealing materials when connecting the male thread to ensure a long-lasting, leak-free joint. Avoid overtightening the threaded connection to prevent damage to the brass insert.
