The MCGUIRE LF165LKF is a flexible lavatory supply kit designed to connect shut-off valves to lavatory faucets in residential and light commercial plumbing installations. The supply line features a chrome-plated finish, a loose key set screw flange, and a 3/8-inch IPS inlet connection on one end with a 3/8-inch OD compression fitting on the other. The flexible construction allows technicians to route the line around obstructions common in vanity cabinet installations without rigid offset fittings. Licensed plumbers and experienced service technicians are the typical installers for this type of supply connection.
This lavatory supply kit is suited for use under bathroom vanities and pedestal lavatory sink installations where a flexible chrome supply line is required. The loose key set screw flange provides a finished appearance at the wall escutcheon and allows controlled tightening without a fixed key. The 3/8-inch IPS to 3/8-inch OD configuration is a standard combination for residential lavatory faucet supply connections.
Designed as an OEM-style replacement supply kit for residential and light commercial lavatory faucet installations requiring a 3/8-inch IPS to 3/8-inch OD flexible chrome supply connection.
Installation is performed by a licensed plumber under applicable IPC and local plumbing code requirements. Shut off the water supply at the angle stop or main before removing the existing supply line. Hand-tighten connections first, then snug with a basin wrench or open-end wrench — do not overtighten compression fittings, as this can crack the fitting seat. Inspect for leaks at both the IPS and OD connections after restoring water pressure.
