WHAT OUR CUSTOMERS SAY…

“Y'all are amazing. I live in Texas and it's faster to order express from Noel's than go to local parts stores. Customers can text Noel's a picture of the part they need and Noel's will find that part or the equivalent and text the link. They have 2-3 day shipping available. The staff answers the phone quickly, politely and they know their stuff! The unit I needed plumbing parts for was built in the 30s. No matter, Noels has me covered. I highly recommend them. Thank you Noel's for your efficient, old school excellence combined with current technology! You have saved me so much time, money, and aggravation! A++++++ ”

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.
