Mcguire LFST07LK Angle Supply Stop Sweat X Od Loose Key

Product Description

The MCGUIRE LFST07LK is an angle supply stop valve designed for shutoff control at fixture supply connections in residential and light commercial plumbing systems. It features a 1/2-inch sweat inlet connection and a 3/8-inch OD compression outlet, making it suitable for connecting supply lines to sinks, lavatory faucets, and similar fixtures. The loose-key design provides an added layer of access control, allowing the valve to be operated only with a removable key. Licensed plumbers and journeyman-level plumbers typically install this fitting during rough-in or finish plumbing work.

This angle stop is used wherever a 90-degree shutoff is required between a 1/2-inch copper supply line and a 3/8-inch OD fixture supply tube. Common applications include bathroom lavatories, kitchen sinks, and other point-of-use shutoff locations in both new construction and retrofit plumbing projects. The sweat inlet requires soldering to a copper supply line, while the OD outlet accepts a standard compression supply line fitting.

Key Features

• Angle valve configuration provides a 90-degree flow path for tight-space installations
• 1/2-inch sweat (solder) inlet connects directly to copper supply piping
• 3/8-inch OD compression outlet accepts standard fixture supply lines
• Loose-key operation restricts valve access to authorized personnel
• Compact body suited for under-sink and in-cabinet installations

Compatibility

Designed as an OEM-style replacement or new-installation angle stop for 1/2-inch copper sweat supply lines terminating to 3/8-inch OD fixture connections in residential and light commercial plumbing systems.

Installation Notes

Installation requires a licensed plumber and standard copper soldering tools including a torch, flux, and lead-free solder per applicable plumbing codes such as the IPC and local amendments. Shut off the main water supply and fully drain the line before soldering the inlet connection. Do not apply heat after the compression outlet fitting or supply line is attached. Verify local code requirements for lead-free compliance before installation.
