Sanitas 33.2020 PPR Brass Coupling D20 x 1/2 inch Male Thread

The Sanitas 33.2020 PPR brass coupling is a professional-grade plumbing component engineered to provide a secure and leak-proof transition between PPR plastic piping and threaded metal fittings. Designed for versatility and longevity, this coupling features a 20 mm diameter connection for PPR pipes and a 1/2 inch male thread for metal components, making it an essential element for modern water supply and heating infrastructure.

Advantages

This coupling stands out due to its robust construction, combining the lightweight and heat-resistant properties of PPR with the structural integrity of high-quality brass. The material composition ensures excellent resistance to corrosion and chemical degradation, which is critical for maintaining water quality and system durability over time. Its precise engineering allows for seamless integration into existing plumbing networks, reducing the risk of leaks and ensuring consistent flow performance in both residential and commercial applications.

Suitable for

• Connecting PPR pipes to threaded metal valves or faucets
• Residential water supply and distribution systems
• Commercial plumbing and heating installations
• Transitioning between plastic and metal piping segments

This fitting may not be suitable for high-pressure industrial steam systems or applications involving aggressive chemicals that are incompatible with brass or PPR materials. It is also not intended for use in environments where the temperature exceeds the rated limits of the PPR piping system.

Key specifications

• Connection type: PPR pipe to male thread
• PPR diameter: 20 mm
• Thread size: 1/2 inch
• Material: PPR and brass

To install the Sanitas 33.2020, ensure the PPR pipe end is cut square and cleaned of any debris. Use a standard PPR welding machine to fuse the plastic side of the coupling to the pipe according to the manufacturer's temperature and timing guidelines. For the threaded side, apply appropriate thread sealant, such as PTFE tape or liquid sealant, before screwing the fitting into the corresponding metal component. Tighten carefully using a suitable wrench to avoid over-torquing.

What to consider before purchase

• Verify the outer diameter of your existing PPR pipe matches the 20 mm specification
• Ensure the threaded connection requires a 1/2 inch male fitting
• Check compatibility with the specific fluid type and operating temperature of your system

Usage recommendations: Always perform a pressure test on the completed installation before concealing the pipes behind walls or flooring to ensure all connections are perfectly sealed and secure.
