Grohe Adagio Pneumatic 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.
