Caroma Invisi Series 2 Bridge Assembly with Bellows | 237275

The Mechanical Link: The Bridge Assembly (237275) is the critical component that sits between your wall buttons and the Invisi Series 2 Outlet Valve.

• The Identification: This part only suits the Series 2 cisterns. You can identify these by the clear or black pneumatic hoses (unlike the thick blue hoses of the Series 1).

• The Failure Point: Those orange bellows move with every single flush. Over time, especially in high-use homes or commercial buildings, the rubber can perish, tear, or lose its “spring,” meaning your button press won’t trigger the blue paddles on the valve.

Genuine Caroma Spare — Part No. 237275 If you press your flush buttons and feel no resistance—or if the buttons stay depressed—the issue is likely located in this bridge assembly. It acts as the pneumatic-to-mechanical converter for the Invisi system.

Why check the 237275 Bridge?

• Wear and Tear: Repeated compression causes the orange bellows to develop hairline fractures. Once air escapes, the flush fails.

• Commercial Durability: This is a common maintenance item for high-traffic bathrooms where the toilet is flushed dozens of times per day.

• Direct Fit: Designed to clip perfectly onto the internal cistern bracket, aligning directly with the outlet valve’s blue paddles.

Complete Your Series 2 Service: If you are opening up your Invisi Series 2 cistern, it is the best time to check the “Inlet” side of the system as well. The matching valve is the Caroma Unifill Inlet Valve, known for its quiet fill and reliability.

• Q: Will this fit my old Water Wafer cistern?

  • A: No. The legacy Water Wafer (Series 1) uses the thick blue hose system and a different “Slave Bellows.” This 237275 assembly is strictly for the modern Invisi Series 2.

• Q: Do I need to replace the whole bridge if only one side is broken?

  • A: This part is sold as a complete assembly to ensure the tension and pneumatic seal are perfectly balanced across both the half and full flush.

Series 1 (The Pioneer): Uses the thick blue pneumatic hoses. Most parts are now discontinued, but we stock the 405041 Inlet and the Compact Button Upgrade Pack. Series 2 (The Modern Standard): Uses clear/thin or black pneumatic tubes and the unifill valve.
