Chicago Faucets 1797-122JKCP
The Chicago Faucets 1797-122JKCP is a genuine OEM flanged lock nut designed to secure faucet components and trim in place. This specialized nut features an integrated flange that acts as a built-in washer, providing a larger surface area to distribute pressure and ensure a rock-solid connection. Finished in a high-luster polished chrome (CP), it is intended for use in visible areas where aesthetic consistency is required. Constructed from high-quality brass, it is engineered to resist corrosion and thread fatigue, making it a reliable choice for high-traffic commercial and institutional restrooms.

Expert Insight:
The 1797-122JKCP is frequently used on concealed bypass valves and remote spout shanks to lock the decorative trim against the wall or deck. Because the flange is part of the nut itself, it simplifies installation by reducing the number of loose parts you have to juggle under a sink or behind a wall. Installation Tip: To maintain the mirror-like finish, always use a smooth-jawed wrench. If you're installing this in a high-vibration environment (like near a commercial dishwasher), a small drop of removable thread-locker can prevent the nut from backing off over time. Pro Tip: If your decorative escutcheon is wobbling, it's usually because this nut has loosened—tightening it back up is often a 30-second fix that saves your trim from getting scratched.
