Hibbent 2-Pack 3-Inch Toilet Flapper — Gerber 99-788 Compatible, Easy Install, Blue

Upgrade your bathroom with the Hibbent 2-Pack Large 3-Inch Toilet Flapper. Carefully engineered to fit 3-inch flush valves, including Gerber 99-788, this replacement helps restore a reliable flush while aligning with common plumbing guidelines. The vivid blue flapper adds a touch of color to the tank, making replacements quick to spot and install.

Key features at a glance

The flapper blends two high-quality materials for lasting performance. A soft, durable rubber seal creates a tight shutoff, while a stainless steel chain resists rust and keeps the lever connected for smooth operation. The assembly measures about 4.9 inches by 3.66 inches, optimized for a 3-inch opening.

• 3-inch flapper compatible with 3-inch flush valves; includes Gerber 99-788 compatibility.
• Soft rubber seal plus stainless steel chain for long life and steady performance.
• Designed to reduce water waste by replacing worn flappers and preventing constant running leaks.

Real-world use cases

Imagine a toilet that once whistled or dripped after every flush. Installing this flapper can help restore a controlled flush cycle and stop the nagging drip. The 2-pack format means you’re prepared for a spare toilet or future maintenance.

What to expect in daily life

Users may notice a more predictable flush rhythm and reduced chances of overflow in households with aging flappers. The blue color helps distinguish a fresh replacement in the tank, and the sturdy chain stays attached through daily use.

Easy setup and care

Replace the old unit by removing the flapper and snapping the new one into place. Attach the chain to the flush lever, adjust as needed, and test the flush. No additional tools required, and you can swap both units in minutes.

Note: Before ordering, double-check that your tank opening is 3 inches in diameter to ensure a proper fit.
