## Long description

The NIBCO 4718-101 water supply coupling is a professional-grade plumbing component engineered for seamless transitions between different pipe sizes. This fitting facilitates a reliable reduction from a 3/4 inch connection to a 1/2 inch connection, ensuring a secure and leak-proof integration within residential or commercial water distribution networks. Manufactured from high-quality chlorinated polyvinyl chloride (CPVC), this coupling is designed to withstand the rigors of daily water supply operations while maintaining structural integrity over time.
Advantages
The primary benefit of this CPVC coupling is its exceptional durability and resistance to corrosion, which is essential for long-term plumbing reliability. Its precise design allows for a smooth transition between pipe diameters, minimizing turbulence and pressure loss within the system. The yellow-colored material is easily identifiable during installation, and the robust construction ensures that the connection remains stable under varying pressure conditions, providing peace of mind for both professional installers and homeowners.
Suitable for
Residential water supply systems
Commercial plumbing infrastructure
Reducing pipe diameter in CPVC piping networks
New construction and renovation plumbing projects
When it may not be suitable
This coupling is specifically designed for CPVC piping systems and may not be compatible with metal pipes or other plastic materials that require different joining methods. It is not intended for high-pressure industrial steam applications or systems where temperatures exceed the specified operating range.
Key specifications
Material: Chlorinated polyvinyl chloride (CPVC)
Connection sizes: 3/4 inch to 1/2 inch
Operating temperature range: 0°C to 80°C
Connection count: 2
Color: Yellow
How to use
To install the NIBCO coupling, ensure that both the pipe ends and the interior of the fitting are clean, dry, and free of debris. Apply an appropriate CPVC solvent cement to both the pipe surface and the inside of the coupling according to the manufacturer's instructions. Insert the pipe into the fitting with a slight twisting motion to ensure even distribution of the cement, then hold firmly for the recommended time to allow the bond to set. Ensure the connection is fully cured before pressurizing the system.
What to consider before purchase
Verify that your existing piping system is compatible with CPVC materials.
Ensure the 3/4 inch and 1/2 inch dimensions match your specific plumbing requirements.
Check that the operating temperature of your system stays within the 0°C to 80°C range.
Usage recommendations
Always use professional-grade solvent cement specifically formulated for CPVC to ensure a permanent, leak-proof seal. Avoid over-tightening or applying excessive mechanical stress to the fitting during installation.
