Chicago Faucets 1-343JKABNF
The Chicago Faucets 1-343JKABNF is a genuine OEM cap gasket engineered to provide a watertight seal between the faucet cartridge and the valve body cap. This critical sealing component is a staple in commercial plumbing maintenance, specifically designed for use with Chicago Faucets' iconic Quaturn™ and Slow-Compression cartridges. As an ECAST® certified part, it is manufactured using high-quality, lead-free materials that meet or exceed NSF/ANSI/CAN 372 standards. This gasket prevents "top-side" leaks—where water seeps out from under the handle or cap—ensuring that your facility's water pressure remains consistent and your fixtures remain free of mineral buildup and water damage.
Pro Tip:
The 1-343JKABNF is often the culprit when you see water pooling around the base of the faucet handle. Because this gasket is compressed every time the faucet is serviced, it should be replaced whenever you pull the cartridge to swap a washer or O-ring. It’s a low-cost "insurance policy" against nuisance leaks. Pro tip: Ensure the seating surface on the valve body is clean of old debris before installing the new gasket for the best seal.
