## Description

This 3-pack of genuine Mansfield 630-0030 flush valve seals is designed specifically for Mansfield tower-style flush valves, including models 210 and 211. It also fits Mansfield Model 160 tanks, which use the 211 flush valve. These red seals are the only ones engineered to properly fit Mansfield tower flush valves and ridged-style flappers, ensuring reliable performance and a watertight seal. Measures approximately 3-1/2" outer diameter and 2-1/4" inner diameter for a secure, leak-free seal.Over time, old seals can develop a ridge or cone shape, leading to toilet leaks or difficulty flushing. Replacing a worn seal with this genuine part is the most common and effective fix. Made from a durable, proprietary compound, these seals outlast standard silicone and generic alternatives by maintaining the perfect balance of softness and support required by the flush valve.Important: Genuine Mansfield parts come sealed in official Mansfield-branded packaging. If your product arrives loose or repackaged, it is not an authentic Mansfield part.For help with installation, step-by-step installation instructions are included on the back of package.

Review: Exact fit for my Mansfield Model 160 tank - Worked perfect valve seal replacement for my Mansfield Model 160 tank. I have the "white" valve and it fit exact. Didn't get it seated correctly first time ... so rotated in the groove more and stopped my leak 100%. Easy installation. This 3 pack at desertcart was $12 and other places wanted $10.50 for one.
Review: Perfect - So we have three Mansfield 210s in the house and they've been rock solid for 20 years. The upstairs one was starting to get pretty difficult to flush and mama was not happy at the leaks, so we called a plumber and he happily quoted us about $500 to swap out the internals on all three. I didn't think that was necessary so I consulted professor internet search and found some thoughts. Turned out after some investigation was the flush valve. No surprise after 20 years of sitting in water it was rotted and came apart in my hand when I touched it. So had to turn the toilet off for a few days until these arrived. The three pack was the perfect amount, value was spot on and they were very easy to install. Our 210s have a ridge that this slides onto, perfect install is being able to turn it inside the ridge. Put everything back together and turned on the water and the fit and functionality were spot on. I flushed it twice just to make sure and checked for leaks, no issues whatsoever. Mama is happy because the handle is easier to move, I'm happy because I saved over $400 on plumber costs and won't be using that plumber again in in the future. Highly recommend, as long as you can confim the flush valve is the issue with your Mansfield Toilet.

### ⭐⭐⭐⭐⭐ Genuine Mansfield flush valve seals get the job done
*by A***R on March 17, 2026*

The rubber flush valve gaskets on Mansfield toilets age over time and begin to shrink, resulting in a seal that leaks water ever so slowly, usually causing an increase in your water bill. They are easily replaced (directions on the pkg.) but be careful to install them on the first lip of the base and be sure the seal turns freely in the groove, as you'll get the proper water-tight seal that way. This pkg of three is the way to go...much less per seal. Always good to have an extra around for quick replacement of the next seal that needs replaced...won't have to wait for a shipment next time! Also, use these genuine Mansfield gaskets....other brands are often cheaply made and will begin leaking prematurely. (I've tried several of the "imitators" with little success )
