Sanitas 34.2020 PPR Brass Coupling D20 x 1/2 inch Female Thread

The Sanitas 34.2020 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 diameter of 20 mm and a 1/2 inch female thread, this coupling provides a robust and reliable interface for various water supply and heating applications. Its design prioritizes structural integrity and long-term performance in demanding environments.

Advantages

This coupling stands out due to its high-quality construction, combining the durability of brass with the chemical resistance of PPR material. The precision-machined threads ensure a tight fit, significantly reducing the risk of leaks in pressurized systems. Furthermore, the material composition offers excellent resistance to corrosion and thermal expansion, ensuring that the connection remains stable even under fluctuating temperature conditions common in residential and commercial plumbing networks.

Suitable for

• Connecting PPR pipes to threaded valves or faucets
• Residential water supply installations
• Heating system piping networks
• Transitions between plastic and metal plumbing components

When it may not be suitable

This coupling is not intended for use in high-pressure industrial steam lines or systems carrying aggressive chemicals that are incompatible with brass or polypropylene. It should also not be used in applications where the pipe diameter or thread size does not match the specified 20 mm and 1/2 inch dimensions.

Key specifications

• Diameter: 20 mm
• Thread type: 1/2 inch female
• Material: PPR and brass
• Application: Plumbing and heating systems

How to use

To install the coupling, ensure the PPR pipe end is cut square and cleaned of any debris. Use a standard PPR welding machine to heat the pipe and the coupling socket simultaneously according to the manufacturer's temperature guidelines. Once heated, insert the pipe into the coupling and hold it steady until the material cools and sets. For the threaded side, apply appropriate thread sealant, such as PTFE tape or liquid sealant, before screwing the threaded component into the female end of the coupling. Tighten with a suitable wrench, taking care not to overtighten.

What to consider before purchase

• Verify the outer diameter of your existing PPR piping
• Check if the connection point requires a male or female thread
• Ensure compatibility with the operating temperature and pressure of your system

Usage recommendations

Always perform a pressure test on the completed installation before concealing the pipes behind walls or floors to ensure all connections are perfectly sealed.
