Merit Brass MB12540 Press Reducing Fitting 1x1/2 Inch

Product Description

The MERIT BRASS MB12540 is a press-style reducing fitting used in copper piping systems to transition from a 1-inch line to a 1/2-inch connection. It features a sweat fitting (FTG) inlet on one end and a press connection on the outlet, allowing plumbers to complete transitions without open-flame soldering at the press end. This fitting is suited for potable water, hydronic heating, and mechanical piping applications where a secure, leak-tested joint is required. At 0.76 pounds, it is compact and straightforward to handle during rough-in or retrofit work.

This reducing fitting is intended for use in residential and light commercial plumbing systems where pipe size reduction is needed along a copper distribution run. It is commonly installed by licensed plumbers during new construction, remodel work, or system expansion. The FTG end accepts a standard copper pipe or fitting for soldering, while the press end eliminates torch work at that connection point, making it a practical choice in occupied spaces or areas with fire-restriction requirements.

Key Features

• Reduces from 1-inch to 1/2-inch copper piping in a single fitting
• Combination FTG sweat inlet and press outlet eliminates torch use at the press connection
• Compact form factor at 0.76 pounds for easy handling in tight spaces
• Suitable for potable water and hydronic piping applications
• Press-style connection provides a consistent, repeatable joint without flux or solder at the press end

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard copper press and sweat piping systems requiring a 1-inch to 1/2-inch reduction.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC standards. Shut off and depressurize the water supply and ensure the pipe is fully dry before making any connection. The press end requires a compatible press tool and jaw set rated for the fitting size. The FTG sweat end should be cleaned, fluxed, and soldered following standard copper joining procedures before system pressurization.
