The size of the bottom piece is what you need to see to order the right flapper.** A: The only guess I can make is that if there is a bar going across the top, it won't fit an older one-piece Kohler toilet so this differenciates it right away. I have the older model so I need this flapper without the black bar. The bar fits between the two extended arms you see in the picture. I made the mistake of ordering the one with the bar, model #GP84995, and it just didn't work. This model, GP83064 is the only one I found that sits on the opening properly and doesn't leak. I think my toilet is from 1989, when my home was built. **Q: Is there a coordinating valve seal for this flapper?** A: No that I know, the flapper seals the hole on the lower part of the water box. **Q: Is this made of chlorazone rubber for chlorine resistance?** A: Hello, yes it is made from chlorazone rubber for chlorine resistance. **Q: Whitch flappers have 2” spacing between straps** A: This one, why? ## Customer Reviews ### ⭐⭐⭐⭐⭐ > DOES THE JOB *by S***Y on July 14, 2013* STOPPING "RUN-ON" IN YOUR OLDER 1-PIECE KOHLER TOILET 1>> Turn the screw in the center of the top of the balcock mechanism ¼ turn to the right. > Repeat as necessary, but don't be too quick to repeat.

This OEM Kohler flapper #83064 works if you have an earlier Kohler Rialto with a square drainage box and metal side lugs. I called Kohler direct to confirm. Apparently some later model Rialto toilets have a different drainage box (plastic and rounded) that requires a different type of Kohler flapper - you cannot always rely on the pictures shown on the back of the package - call Kohler if you are not sure. ## Frequently Bought Together - Kohler KO-83064 GENUINE PART GP83064 FLAPPER FOR SELECT ONE-PIECE TOILETS - KOHLER Silent Fill Toilet Valve Kit, Genuine Part GP1138930, Adjustable with Multiple Fill-Rate Inserts - Kohler GP83888 Gasket for Some Toilets --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/5845873-ko-83064-genuine-part-gp83064-flapper-for-select-one-piece](https://www.desertcart.no/products/5845873-ko-83064-genuine-part-gp83064-flapper-for-select-one-piece) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-10-21*
