Crafted from heavy-duty, flexible premium rubber, this 3-inch replacement flush valve seal stops leaks right at the source. Thanks to its smart screw-on design, the seal disc actively pivots against the tilt-valve base to guarantee a perfect drop-in alignment with every single flush. The tool-free, screw-on design means you can easily thread off your hardened, old seal and snap this replacement disc directly onto the actuating unit within minutes.

“The vacuum breaker on my outdoor spigot failed and Noel's Plumbing was the only placeI could find that had the appropriate mfr. part. I sent a text with photos on Wednesday evening to make sure the part I found was correct. In less than 2 hours later, I had a reply confirming it was the correct part. Placed my order that evening and received the part on Saturday afternoon (about 2.75 days) and my plumbing issue was resolved! I highly recommend - I really appreciated the prompt and pleasant response. ”
