The MCGUIRE MFG lf165lk is a flexible lavatory supply kit designed for connecting water supply lines to lavatory faucets in residential and light commercial plumbing applications. Finished in chrome, it features a 3/8-inch IPS inlet connection on one end and a 3/8-inch OD compression outlet on the other, with a loose key shutoff valve included. The lead-free construction meets current safe drinking water standards, making it code-compliant for potable water service. This supply kit is a standard tool-of-the-trade item installed by licensed plumbers and plumbing contractors during faucet installation or replacement.
This flexible supply kit is suited for under-sink lavatory installations in bathrooms, powder rooms, and similar wet areas. The chrome finish blends with standard chrome fixture trim. The loose key valve allows for shutoff without a built-in handle, which is preferred in some commercial or semi-public settings where valve tampering is a concern. Compatible with standard lavatory faucet supply inlets using 3/8-inch OD compression fittings.
Designed as an OEM-style replacement or new-installation supply kit for residential and light commercial lavatory faucet applications using 3/8-inch IPS by 3/8-inch OD connections.
Installation is performed by a licensed plumber or qualified plumbing technician. Shut off the water supply at the main or angle stop before beginning work. Hand-tighten compression fittings first, then snug with a wrench — avoid overtightening, which can crack ferrules or damage fittings. Work should comply with applicable local plumbing codes and IPC standards for potable water supply connections.
