Legend Valve MB12300 Press Coupling Without Stop 3/4 in

Product Description

The LEGEND VALVE MB12300 is a 3/4-inch press-fit coupling designed without an internal tube stop, allowing pipe to pass fully through the fitting during assembly. This configuration is commonly used when making repairs on existing lines where a standard coupling with a tube stop cannot slide into position. The fitting uses a press-connection system, eliminating the need for open flame soldering. It is installed by licensed plumbers and pipefitters working on copper or compatible piping systems in both residential and light commercial applications.

The MB12300 fits 3/4-inch press-fit piping systems and is suited for repair and retrofit work where pipe travel through the coupling body is required. Typical installations include water distribution lines, hydronic heating loops, and similar closed-loop or supply piping systems. The press-without-stop design is a standard solution when a damaged section of pipe is being cut out and a repair coupling must slide over the remaining pipe ends before being pressed into final position.

Key Features

• Press-fit connection eliminates open-flame soldering for faster, safer installation
• No internal tube stop allows full pipe pass-through for in-line repair work
• 3/4-inch nominal size fits standard press-fit piping systems
• Compact coupling profile suitable for tight installation spaces

Compatibility

Designed as an OEM-style press-fit repair coupling for 3/4-inch residential and light commercial piping systems where a through-pass coupling configuration is required.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with press-fit tooling and manufacturer-approved jaw sets. Shut off water supply and depressurize the line before cutting out the damaged section and positioning the coupling. Always verify that pipe ends are clean, deburred, and properly marked to the insertion depth before pressing. Follow local plumbing codes, including applicable IPC requirements, for press-connection fittings in your jurisdiction.
