I can’t speak for durability, but worked perfectly making the shower usable again. ### ⭐⭐⭐⭐⭐ prefect *by on Reviewed in the United States May 25, 2020* Genuine part delivered fastI purchased this unit because my shower temperature became uncontrollable. It would either be very hot or very cold, but never the right mix. So, I searched the Kohler online to find the solution, it suggested that I should change the cartridge, then I ordered it on line. Surprisingly, it was delivered the very next day. Installation was easy even for a novice just 4 steps, there was still videos online. I simply replaced the old part and rings with matching new ones. Two wide black rings for the outside and the two small black rings for the inside. For now, it seems to have solved the temperature control problem, but how long this lasts the time will tell us. We are so happy our shower just like the new again. ### ⭐⭐⭐⭐⭐ valve leak not due to the pressure unit *by on Reviewed in the United States November 26, 2023* After installing, the valve leaked. Turns out it had nothing to do with the replacement cartridge. After much on line searching, I found the valve housing was corroded where the main o-ring seals. There was scaling and green corrosion on the brass housing causing a rough surface and a leak at the o-ring seal. I used a light acid solution to remove most of the corrosion and scale then I used 800, 1000, 3000, 5000, 7000 and 10,000 grit wet paper to polish the surface. Added a little silicon grease to the o-ring and valve surface, reassembled and the leak was gone. The unit functions perfectly. I would not be surprised if some of the "leaking" problems reported by others were not due to this issue.Also, I disassembled the failed pressure cartridge out of curiosity and found the internal pressure diaphragm was completely rotted away causing random mixing and unstable/unpredictable temperatures. This failure also caused the nearby bathroom sink to have hot water coming from the cold faucet! That was a very bizarre and confusing symptom.Hope this helps someone. ## Frequently Bought Together - GP500520 Pressure Balancing Unit Cartridge Replacement, Compatible With Kohler Shower Cartridge, Kohler Shower Valve, Rite-Temp Bath and Shower 1/2" Single Handle valves 1pcs - KOHLER GENUINE PART GP77759 MIXER CAP FOR PRESSURE BALANCE 1/2" SHOWER VALVE - DANCO Waterproof Silicone Faucet Grease | Silicone Sealant | Plumbers valve Grease for O-rings | 0.5 oz. | 1-Pack (88693) --- ## 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.tn/products/203955519-gp500520-pressure-balancing-unit-cartridge-replacement-compatible-with-kohler-shower](https://www.desertcart.tn/products/203955519-gp500520-pressure-balancing-unit-cartridge-replacement-compatible-with-kohler-shower) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-05*
