Chicago Faucets 2-043JKABNF
The Chicago Faucets 2-043JKABNF is a genuine OEM O-Ring designed specifically for the XT Style operating cartridges found in Chicago Faucets' commercial manual and metering fixtures. This precision-molded seal is the primary barrier that prevents water from bypassing the cartridge and leaking from the handle or the top of the faucet body. As an ECAST® (ABNF) lead-free component, it is manufactured to meet the most stringent federal and state requirements for potable water safety. This O-ring is engineered to maintain its elasticity and sealing profile under the high-pressure and frequent-use conditions of institutional environments.
- Overall Height: 5/64"
- Outside Diameter: 13/16"
- Inside Diameter: 43/64"
Expert Insight:
The 2-043JKABNF is the "missing link" in a successful XT-style cartridge rebuild. Installation Tip: When you pull an XT cartridge (like the 1-099XT), you'll often see this O-ring has flattened or "squared off" due to compression. Always swap this out when you pull the cartridge, even if it doesn't look broken; once the original compression set is broken, it rarely reseals perfectly a second time. Pro Tip: Use a plastic O-ring pick to remove the old seal to avoid scratching the brass cartridge housing. A single scratch in the metal can create a "micro-channel" that will leak even with a brand-new O-ring. Because this is the ABNF version, it’s safe for all drinking water applications.
