Fluidmaster Flush Valve Cap - 350

Fluidmaster Flush Valve Cap - 350

Restore the flush-valve cap and seal interface with this Fluidmaster Flush Valve Cap - 350. This flush valve cap closes the compatible valve body and supports the sealing/operating components required for proper toilet flush-valve operation.

350 is a universal / spec-match item selected by its verified product identity, dimensions, ratings, connections, or application rather than by appearance alone.

Fitment / What To Verify: Match tubing/hose size, length where relevant, end connections or threads, material, pressure/application, and routing. Leak-test all fluid or gas connections after installation.

Is it time to replace?

• Common Symptoms: The valve may leak, fail to shut off correctly, or the existing cap may be cracked, stripped, missing, or unable to retain the internal components.
• Visible/Sensory Cues: Cracks, damaged threads/tabs, mineral buildup, distortion, or leakage around the cap are common cues.

Pro Tip: Shut off the water and match the exact Fluidmaster valve family and cap interface before ordering; inspect the seal and valve body at the same time.
