Product Overview
The ZNBSIXP Flush Valve Seal is engineered for durability and performance. Crafted from premium silicone rubber, the 4.25‑inch blue seal provides a watertight barrier that resists wear, temperature fluctuations, and chemical exposure. Its compression inlet and rubber washer‑nut outlet ensure a secure fit without the need for additional tools. Weighing just 1.76 ounces, the lightweight design simplifies handling while maintaining robust sealing power. Compatible with American Standard Champion 4 and Eljer Titan 4 models, this seal replaces the original O‑ring to restore optimal flushing efficiency.

FAQ
Will this seal fit my older toilet model?
The seal is designed for 4.25‑inch outlets, which are standard on most American Standard Champion 4 and Eljer Titan 4 toilets. If your toilet uses a different size, we recommend measuring the outlet diameter before purchase.
Do I need any tools to install the seal?
No special tools are required. The compression inlet and rubber washer‑nut outlet allow you to press the seal into place by hand, making the installation quick and hassle‑free.
How does the seal reduce noise?
The silicone rubber material dampens vibrations caused by water flow, significantly lowering the audible sound of each flush.
Is the seal reusable if I need to remove it?
While the seal can be removed, repeated removal and re‑installation may compromise its elasticity. For best results, replace the seal if it has been taken out more than once.
What warranty does ZNBSIXP offer?
We provide a one‑year limited warranty covering manufacturing defects. Contact our support team with your purchase details for assistance.
