Product Identity

The Chicago Faucet Company 1-021JKABNF cartridge seat washer is a replacement component for specific faucet models. It measures 0.565 inches in diameter and fits manufacturer model 1276-ABNF. This new part addresses wear in compatible bathroom fixtures. Plumbers and homeowners repairing compatible Chicago Faucet units will find this direct-fit washer essential for restoring proper sealing function.

Fitment Guidance

This washer suits technicians servicing Chicago Faucet model 1276-ABNF fixtures requiring a 0.565 inch diameter seat washer. Buyers needing washers for different manufacturers, alternative Chicago Faucet models, or other diameters should verify compatibility before purchasing. The part includes no additional hardware, so installers must supply any required tools or supplementary seals separately.

Critical Specification

The decisive measurement is the 0.565 inch diameter, which must match the original seat washer exactly for proper sealing. Confirm the faucet is model 1276-ABNF before ordering, as this washer is engineered for that specific assembly. An incorrect diameter will prevent proper cartridge seating and cause persistent leaks.

Questions about this item

How often should the 0.565 in cartridge seat washer be replaced in a 1276-ABNF faucet?

Replace the washer when dripping appears at the spout or handle; the rubber seat compresses over time and loses seal integrity in the 1276-ABNF cartridge assembly.

What fails first when the 1276-ABNF faucet runs continuously?

The 0.565 in seat washer deforms under constant pressure and temperature cycling, causing leaks before the cartridge body or handle mechanism wears.

Does the 0.565 in washer affect water noise or temperature stability in the 1276-ABNF faucet?

A worn washer lets water bypass the seat, creating chatter or whistle and allowing hot and cold cross-flow that shifts outlet temperature.
