About this item
- Perfect Fit for Geberit & Fluidmaster Systems:Our 63x33x2mm flush valve seal is designed to replace worn-out washers in Geberit dual flush valves and Fluidmaster toilet cisterns. Ensures a watertight seal to prevent leaks and maintain efficient flushing.
- Durable: High-quality rubber diaphragm for long life, the seal is made of flexible and durable EPDM rubber that withstands constant water pressure and resists deformation, ensuring years of reliable sealing without cracking or hardening.
- Cost-effective: 3-piece value pack that can be replaced multiple times and includes 3 identical seals - ideal for immediate repairs and future replacements. Save time and money compared to buying a single gasket.
- Easy to install: DIY is easy to install in minutes, no plumber required! Simply remove the old seal, clean the seat, and press the new Geberit diaphragm into place. Fits standard 63mm flushometers.
- Reduced losses: Prevent costly water waste and leaks, poor seals can lead to persistent water leaks. Our replacement gaskets ensure a tight seal, reduce water bills and prevent tank damage.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
