Vacuum Button for 204-4-Arm Handles

This vacuum button is a genuine Chicago Faucets replacement part designed specifically for 204-4-arm handles. It restores the vacuum breaker function on compatible commercial or institutional faucets. The component is supplied new and ready for installation.

Suits maintenance on Chicago Faucets 204 series

The button fits only the 204-4-arm handle configuration, so it suits maintenance teams standardised on that hardware. It will not work on other handle styles, different brands, or faucets lacking the 204 arm pattern. Buyers needing a different handle interface should look elsewhere.

Simple press-fit replacement

Installation typically involves removing the old button and pressing the new plastic unit into the handle arm. The 7/16 inch height and 3/4 inch width and length match the original cavity. The most common issue is ordering the wrong button for a non-204 handle, which prevents proper seating.

Questions about this item

Do I need a 204-4-Arm handle already installed for this vacuum button to fit?

Yes, this button is made for use with 204-4-Arm handles only.

Will the button work if I keep my existing faucet body and only replace the handle button?

It replaces the button on a 204-4-Arm handle, so the handle must already be that model.

How can I confirm the button is seated correctly after I press it into the handle?

The plastic button sits flush at 7/16 in. height and 3/4 in. square when fully installed.
