Mueller Streamline press-pf01326 Copper Press Reducer

Product Description

The MUELLER STREAMLINE press-pf01326 is a copper press reducing fitting designed to transition from a 3/4-inch fitting (Ftg) connection to a 1/2-inch press connection in pressurized water and hydronic piping systems. This fitting eliminates the need for open-flame soldering, using a press-tool crimping method to create a watertight mechanical joint. It is commonly installed by licensed plumbers and pipefitters working on residential and light commercial water supply lines. The Ftg x Press configuration allows one end to slip into a standard copper fitting socket while the other end accepts a press-tool connection, streamlining retrofit and new-construction installations.

This reducing fitting is suited for potable water supply, hydronic heating, and general plumbing applications where reducing pipe size from 3/4 inch to 1/2 inch is required. The press-connect end is compatible with standard press tooling used on copper press-fit systems. It is a practical choice for service work in occupied spaces where open flame is restricted or undesirable, and for installers looking to reduce labor time on joining operations.

Key Features

• 3/4-inch Ftg (fitting) inlet accepts standard copper fitting socket connections
• 1/2-inch press outlet for tool-crimped, solder-free mechanical joint
• Copper construction provides corrosion resistance in water piping systems
• Reduces pipe diameter in a single fitting, eliminating extra couplings
• No open flame required — suitable for installs in flame-restricted environments

Compatibility

Designed as an OEM-style copper press reducing fitting for use in standard residential and light commercial copper press-fit piping systems. Compatible with press tooling designed for copper press fittings in the corresponding sizes.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following local plumbing codes and IPC guidelines. Shut off water supply and depressurize the line before installing or removing any fitting. Use only a press tool and jaw set rated for copper press fittings and sized for the applicable connection diameter. Verify the pipe end is clean, deburred, and fully inserted to the fitting stop before crimping.
