Mcguire Mfg lf2165cclkfss20 Loose Key Supply Kit

Product Description

The MCGUIRE MFG lf2165cclkfss20 is a loose key supply stop kit designed for under-sink water supply connections in residential and light commercial plumbing applications. The kit uses a 1/2-inch compression inlet and a 3/8-inch compression outlet, making it compatible with standard supply stop configurations found on sinks and lavatories. It ships with 20-inch braided hoses, providing the flexible supply lines needed to connect the stop valve to a faucet tailpiece. Licensed plumbers and experienced service techs install this type of kit during fixture replacements, remodels, or supply stop service calls.

This supply kit is suited for installations under lavatories, kitchen sinks, and similar fixtures where a compression-style angle stop is required. The 1/2-inch compression inlet connects to the water supply line stub-out, while the 3/8-inch compression outlet feeds directly to the faucet supply shank. The 20-inch hose length accommodates standard cabinet depths. The loose key design allows the stop to be operated without a built-in handle, using a utility key or shut-off tool instead, which is a common requirement in commercial or semi-public installations where uncontrolled user access to the valve is not desired.

Key Features

• 1/2-inch compression inlet x 3/8-inch compression outlet configuration
• Includes 20-inch braided supply hoses
• Loose key valve design restricts unauthorized operation of the stop
• Compression fittings require no soldering for installation
• Suitable for residential and light commercial under-sink applications

Compatibility

Designed as an OEM-style replacement or new-installation supply stop kit for standard compression-connection angle stop applications at sinks and lavatories with 1/2-inch compression supply line stub-outs and 3/8-inch compression faucet connections.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off the main water supply or the appropriate branch isolation valve and relieve line pressure before beginning work. Compression fittings should be hand-tightened then snugged with a wrench — do not overtighten, as this can crack the compression sleeve. Verify all connections for leaks after restoring water pressure before closing out the service call.
