Rwc UIP4008 Transition Coupling 1/2 Inch Cts X Pvc Brass

Product Description

The RWC UIP4008 is a 1/2 inch nominal transition coupling designed to connect CTS (Copper Tube Size) pipe to PVC pipe in a single fitting. Constructed from brass, this coupling provides a durable, corrosion-resistant connection between two of the most common pipe materials used in residential and light commercial plumbing systems. It is well-suited for repair, retrofit, and new installation work where a transition between flexible plastic tubing and rigid PVC is required. Licensed plumbers and experienced DIYers install this type of fitting where material changeovers occur in supply or distribution lines.

The UIP4008 is used in residential and light commercial plumbing applications where a pipe material transition is necessary. Common scenarios include connecting PEX or polyethylene CTS tubing to existing PVC supply lines, adapting new flexible tubing runs to legacy rigid PVC distribution systems, or making repairs where two different pipe materials meet. The 1/2 inch nominal size covers the most frequently encountered residential supply line diameter.

Key Features

• 1/2 inch nominal size fits the most common residential supply line diameter
• CTS x PVC end configuration allows direct connection between two distinct pipe materials
• Brass construction provides corrosion resistance and durability in wet environments
• Transition design eliminates the need for additional adapters or glue-on couplings at the changeover point

Compatibility

Designed as an OEM-style replacement and standard-use transition fitting for 1/2 inch nominal CTS to PVC plumbing connections in residential and light commercial systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC) where applicable. Shut off the water supply and relieve system pressure before cutting into any existing line. Ensure pipe ends are cleanly cut, deburred, and free of debris before making the connection. Follow the fitting manufacturer guidelines for insertion depth and joint preparation on the PVC side.
