Chicago Faucets 1797-129JKABNF
The Chicago Faucets 1797-129JKABNF is a genuine OEM replacement rubber washer designed for sealing faucet shanks and mounting assemblies. This flat rubber washer is a critical "soft goods" component that creates a watertight barrier between the faucet body and the mounting surface, preventing water from seeping through the sink deck and damaging the cabinetry or flooring below. As part of the AB (Lead-Free) lineup, this washer is made from high-grade, chemical-resistant elastomers that meet all modern plumbing standards. It is specifically sized to fit standard Chicago Faucets mounting shanks, ensuring a snug fit and long-term durability in high-use commercial environments.
- Overall Height: 3/16"
- Outside Diameter: 9/16"
- Inside Diameter: 11/32"
Expert Insight:
The 1797-129JKABNF is often the "missing link" during a faucet reinstall. Over years of use, the original rubber can become brittle or compressed, leading to those annoying puddles inside your vanity or under your prep sink. Installation Tip: When replacing this washer, ensure the underside of the sink deck is completely clean and dry. Even a small amount of old plumber's putty or mineral buildup can prevent this rubber from seating properly. Pro Tip: This washer is designed to be paired with the metal friction washer and the mounting nut. If you're doing a full maintenance overhaul on a commercial sink, we recommend replacing these every time you pull the faucet to guarantee a leak-free seal on the first try.
