Chicago Faucets 1797-114JKNF
The Chicago Faucets 1797-114JKNF is a genuine OEM replacement basin cup washer (also known as a friction or mounting washer) designed for use with commercial faucet shanks and basin installations. This specialized washer is engineered to provide a stable, cushioned seal between the faucet body and the mounting surface (sink or countertop). Its unique "cup" profile helps distribute the clamping force of the mounting nut evenly, preventing the fixture from wobbling or shifting over time. Constructed from high-quality, durable materials, the 1797-114JKNF is built to resist the constant moisture and pressure common in high-traffic commercial environments.
- Overall Height: 3/4"

Expert Insight:
The 1797-114JKNF is one of those small parts that makes a huge difference in the longevity of your installation. If your faucet feels loose or "spins" when you turn the handles, this washer has likely flattened out or perished. Installation Tip: When installing, ensure the "cupped" side is oriented correctly against the underside of the basin or the friction washer to create a proper tension lock. Pro Tip: Over-tightening the mounting nut can actually deform this washer and cause the sink deck to flex or crack, especially on stainless steel or thin china. Tighten until the faucet is immobile, then give it just a quarter-turn more. Always check for debris on the mounting shank threads before sliding this washer on to ensure a smooth fit.
