Merit Brass MB12490 Press Reducing Coupling 2x3/4 in

Product Description

The MERIT BRASS MB12490 is a press-fit reducing coupling designed to connect two pipes of different diameters without soldering or threading. Transitioning from a 2-inch line down to a 3/4-inch line, this coupling installs using a standard press tool, creating a secure, permanent joint suitable for potable water, hydronic heating, and other common piping systems. At 1.4 pounds, the MB12490 is a compact, durable fitting appropriate for installation by licensed plumbers and pipefitters working on residential or light commercial projects.

This reducing coupling is used where a pipe run must step down in diameter, such as branch takeoffs from a main supply line or transitions into fixture supply lines. The press connection method eliminates open flame, making it well suited for installations in tight spaces, near combustible materials, or in jurisdictions where soldering is restricted. It is appropriate for use in new construction and retrofit applications alike.

Key Features

• Press-fit connection eliminates the need for soldering, threading, or gluing
• Reduces from 2 inches to 3/4 inches in a single fitting
• Permanent, reliable joint suitable for pressurized piping systems
• Compact form factor at 1.4 pounds for easy handling in confined spaces
• Flame-free installation reduces fire risk and speeds up workflow

Compatibility

Designed as an OEM-style press-fit reducing coupling for 2-inch by 3/4-inch pipe connections in residential and light commercial plumbing and hydronic systems.

Installation Notes

Installation must be performed by a qualified plumber using a compatible press tool with the correct jaw size for both the 2-inch and 3/4-inch ends. Always shut off the water supply and depressurize the line before installation. Ensure pipe ends are clean, deburred, and fully inserted to the stop before pressing. Follow applicable local plumbing codes and IPC guidelines for fitting selection and system pressure ratings.
