Grohe Adagio Pneumatic Single Flush Air Button Service Bellows - 113219

The Genuine Grohe 113219 Black Rubber Bellows is the essential service component for the Grohe Adagio pneumatic single-flush push button system. If your flush button has lost its "spring" or no longer activates the flush valve, the internal bellows have likely perished or split. This replacement part allows you to repair the existing button assembly (38488 / 38388) without the cost of replacing the entire chrome housing.

Maintenance Tip

To install, carefully remove the chrome button from the wall or furniture to access the rear housing. Pop out the old, worn bellows and replace them with the new 113219 unit. Ensure the air tube is firmly reattached to the nipple on the rear of the bellows for consistent flushing performance.
