Product Description
The MUELLER STREAMLINE press-pf10145 is a 1/2-inch copper press coupling with stop, designed for use in pressurized water supply and hydronic systems. The integrated stop allows for consistent insertion depth during assembly, reducing the risk of incomplete joint engagement. This fitting uses a press-style connection that eliminates open flame during installation, making it suitable for retrofit and new construction applications where torch work is restricted or impractical. Licensed plumbers and pipefitters working on residential and light commercial copper pipe systems are the primary installers of this fitting.
This coupling is configured PxP, meaning both ends accept standard copper pipe in a press connection. It is used in cold and hot water distribution systems, hydronic heating lines, and other copper pipe assemblies where a reliable, solder-free mechanical joint is required. The with-stop design seats the pipe at a fixed depth on both sides, which helps ensure full engagement of the press seal on each end.
Key Features
- Press-style connection eliminates the need for soldering or open flame
- Integrated pipe stop ensures consistent insertion depth on both ends
- PxP configuration joins two copper pipe runs in a straight coupling
- 1/2-inch nominal size fits standard 1/2-inch copper pipe
- Suitable for pressurized potable water and hydronic piping systems
Compatibility
Designed as an OEM-style press fitting for use with standard 1/2-inch copper pipe in residential and light commercial plumbing and hydronic systems.
Installation Notes
Installation requires a compatible press tool and jaw set rated for copper press fittings of this size. Shut off and depressurize the water system before cutting or joining pipe. Ensure pipe ends are cut square, deburred, and fully seated against the stop before pressing. Work must comply with applicable local plumbing codes and standards such as the IPC or UPC.
