Review: Amazing part - great customer services - 11/10 customer service. I bought a Fluidmaster 5403 3-Inch flapper in November 2021. In March 2026 4 1/2 years later it had developed a small blister on its O-ring and would not seal correctly. Typical wear I assumed. As I was ordering another one I saw it had a ten year warranty. After ordering the new one I went to the Fluidmaster web page and found the warranty information. I filled in and sent the warranty form and 45 minutes later I got an email with a FedEx tracking number saying a replacement part was on its way. The new part got here in 3 days. This flapper fits perfectly - took on a minute to install - and works great. Not only is this a great part that does the job the customer services was bonkers good. From now own Fluidmaster will be used for all my toilet needs. The people at Fluidmaster shall sit amongst the chosen. Review: Toilet Flapper that Fixed the Issue Right Away - I bought this because a couple of toilets were constantly running, and this fixed the problem immediately. Installation was pretty simple, just a few adjustments and it was done. Pros: • solved running toilet issue • straightforward installation • good seal once installed • has held up well for a couple of months • 10-year warranty adds peace of mind • great value for money pack • great replacemnt Cons: • no major negatives so far This ended up being a simple but very effective fix. No issues since installing it. ## Features - Size: 3 Inch.Fluidmaster Universal flapper 3 - 191415 - This is highly durable - Universal flapper - Easy to install with two simple adjustments - Durable silicone seal - Kink free chain - 10 Year warranty - Note: This product is designed to fit toilets with 3″ flush valves ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002C1AVV8 | | Best Sellers Rank | #3,196 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #4 in Toilet Flappers | | Brand | Fluidmaster | | Brand Name | Fluidmaster | | Connector Type | Socket | | Customer Reviews | 4.5 out of 5 stars 7,338 Reviews | | Exterior Finish | Red | | Global Trade Identification Number | 00039961015433 | | Included Components | Fluidmaster 5403 3-Inch Universal Water Saving Long Life Toilet Flapper | | Inlet Connection Size | 3 Inches | | Inlet Connection Type | 3-inch flush valve | | Item Dimensions | 5.25 x 9 x 3.25 inches | | Item Type Name | Fluidmaster 5403 3-Inch Universal Water Saving Long Life Toilet Flapper | | Item dimensions L x W x H | 5.25 x 9 x 3.25 inches | | Manufacturer | Fluidmaster | | Manufacturer Part Number | 5403 | | Manufacturer Warranty Description | Lifetime | | Material | Rubber | | Material Type | Rubber | | Model Number | 5403P4 | | Number of Ports | 2 | | Outlet Connection Size | 3 Inches | | Outlet Connection Type | 3-inch flush valve | | Set Name | Toilet Valve Set | | Size | 3 Inch | | Smart Home Compatibility | Not Smart Home Compatible | | Thread Size | 3 inches | | Thread Type | 3 inches | | UPC | 039961015433 | | Unit Count | 1.0 Count | | Valve Type | standard | ## Product Details - **Brand:** Fluidmaster - **Exterior Finish:** Red - **Global Trade Identification Number:** 00039961015433 - **Inlet Connection Size:** 3 Inches - **Inlet Connection Type:** 3-inch flush valve - **Item dimensions L x W x H:** 5.25 x 9 x 3.25 inches - **Material:** Rubber - **Number of Ports:** 2 - **Outlet Connection Size:** 3 Inches - **Outlet Connection Type:** 3-inch flush valve ## Images ![Fluidmaster 5403 3-Inch Universal Water Saving Long Life Toilet Flapper - Image 1](https://m.media-amazon.com/images/I/51prkVwBUlL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing part - great customer services *by C***N on March 24, 2026* 11/10 customer service.
