Legend Valve 101R-KF Copper Reducing Coupling 3/4x1/2

Product Description

The LEGEND VALVE 101R-KF is a copper reducing coupling designed to connect two different pipe sizes in a plumbing or hydronic system. It transitions from a 3/4-inch nominal inlet to a 1/2-inch nominal outlet, allowing technicians to adapt supply lines, branch connections, or distribution runs without additional fittings. Licensed plumbers and pipefitters install this type of fitting in residential and light commercial applications where pipe sizing changes are required along a water supply or heating distribution line.

This reducing coupling is suited for use in domestic water supply systems, radiant heating loops, and general plumbing rough-in work. It is installed wherever a run of 3/4-inch copper pipe must transition down to 1/2-inch copper, such as at branch takeoffs feeding fixtures, appliances, or zone valves in hydronic systems.

Key Features

• Transitions 3/4-inch nominal copper pipe to 1/2-inch nominal copper pipe in a single fitting
• Copper construction provides corrosion resistance and long service life in water systems
• Sweat-solder end connections compatible with standard copper tube and fittings practice
• Compact reducing coupling profile minimizes installation space requirements

Compatibility

Designed as an OEM-style replacement and general-use reducing coupling for 3/4-inch nominal to 1/2-inch nominal copper pipe systems in residential and light commercial plumbing applications.

Installation Notes

Installation is performed by a licensed plumber following local plumbing codes and IPC requirements. Shut off and drain the supply line completely before cutting and fitting. Use appropriate flux and lead-free solder when making sweat connections, and allow joints to cool fully before restoring pressure. Inspect the joint for leaks after pressure is restored before closing the wall or concealing the work.
