The Mansfield 210/211 Flush Valve Seal 630-0030 is the essential replacement gasket used to fix ghost flushing, slow leaks, or a stiff flush handle. Over time, the original flat seal stretches, deteriorates, or takes on a cone shape, breaking the watertight seal at the bottom of the toilet tower.

We can ship anywhere the US Postal Service ships. For orders being shipped outside the US, please contact us at (888) ASK-NOEL, asknoel@noelsplumbingsupply.com, or via the text widget on this screen.

“Outstanding fast delivery on two pieces of an ancient Wolverine bath stem for Kohler - from the early 40s I think. The new one has a different body design, but it screwed directly into the old hot/cold tree and was the exact 6" length. Forty eight hours after installation now, and all remains fine. Also, kudos to the people who set up the website and ordering process. Great work - clear photos and info ! PS: I'm not an employee or family...lol. I retired from electrical wholesaling here outside Chicago and I appreciate a good job. ”
