Sanitas 34.3232 PPR Brass Coupling D32 x 1 Inch Female Thread

The Sanitas 34.3232 PPR brass coupling is a professional-grade plumbing component engineered for seamless transitions between PPR piping systems and threaded metal fixtures. With a diameter of 32 mm and a 1-inch female thread, this fitting provides a robust and reliable connection point for various water supply and heating applications. Its design prioritizes structural integrity and long-term performance in demanding environments.

Advantages

This coupling offers exceptional durability due to its high-quality brass construction, which provides superior resistance to corrosion and mechanical stress compared to standard plastic fittings. The precision-engineered threads ensure a tight, leak-proof seal when connected to metal pipes or valves. Furthermore, the PPR side of the coupling allows for a secure, permanent thermal fusion weld, creating a homogenous joint that maintains the integrity of the entire piping network under varying pressure and temperature conditions.

Suitable for

• Connecting PPR pipes to metal threaded valves or faucets
• Residential and commercial water supply installations
• Heating system pipework transitions
• Renovation projects requiring mixed-material piping connections

When it may not be suitable

This fitting is not intended for use with non-PPR piping materials on the fusion side, as it requires thermal welding for a proper seal. It is also not suitable for high-pressure industrial steam lines or systems where the chemical composition of the fluid may react negatively with brass or polypropylene.

Key specifications

• Diameter: 32 mm
• Thread size: 1 inch female
• Material: PPR and brass
• Connection type: Thermal fusion and threaded

How to use

To install the coupling, first ensure the PPR pipe end is clean and properly prepared for welding. Use a standard PPR fusion welding machine to heat both the pipe and the coupling socket according to the manufacturer's recommended time and temperature settings. 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, to the male metal component before screwing it into the female thread of the coupling. Tighten carefully using a wrench to avoid over-torquing.

What to consider before purchase

• Verify the outer diameter of your existing PPR pipe
• Ensure the thread type of your metal component matches the 1-inch female thread
• Check that you have the correct fusion welding equipment available

Usage recommendations

Always perform a pressure test on the system after installation to ensure all joints are completely leak-free before concealing the pipes behind walls or under floors.
