The MCGUIRE MFG lf170lk is a chrome lavatory supply kit designed for residential and light commercial faucet supply connections. It features a 1/2-inch sweat (SWT) inlet connection with a 5-inch extension and a 3/8-inch OD compression outlet, terminating with a loose key angle stop configuration. Built to lead-free standards, this flexible supply kit meets potable water compliance requirements for modern plumbing installations. Licensed plumbers and experienced service pros reach for this kit when connecting lavatory faucets to standard supply stop valves, particularly where the rough-in depth requires additional extension to reach the faucet tail piece.
This supply kit is suited for lavatory basin installations in bathrooms where a 1/2-inch sweat inlet stub-out is present and a 3/8-inch OD outlet connection to the faucet is required. The 5-inch extension accommodates deeper vanity cabinets or longer stub-out distances. The chrome finish integrates cleanly with standard lavatory trim. The loose key angle stop allows shutoff control without a built-in handle, which is common in applications where access management is preferred.
Designed as an OEM-style replacement or new-installation supply kit for lavatory faucets requiring a 1/2-inch sweat inlet and 3/8-inch OD outlet angle stop configuration.
Installation is performed by a licensed plumber. Shut off the main water supply or zone supply valve and relieve line pressure before beginning work. The sweat inlet connection requires a torch, flux, and lead-free solder in accordance with applicable plumbing codes such as the IPC. Do not overtighten the compression fitting at the faucet tail piece, as this may crack the fitting or damage the supply tube.
