The Kohler 1131496 is a genuine dual-flush canister valve seal designed specifically for Kohler dual-flush toilets that feature a top-of-tank twin actuator button. Over time, water chemistry causes the original seal to warp or blister, leading to a slow, ghost-flushing leak into the bowl. This part is the direct solution to stop that leakage and restore proper flushing efficiency.

We can ship anywhere the US Postal Service ships. For orders being shipped outside the US, please contact us at (888) ASK-NOEL, asknoel@noelsplumbingsupply.com, or via the text widget on this screen.

“This place is amazing. I live in San Antonio, Texas and there are a few plumbing stores with vintage parts but they never have what I need and the ordering process takes them weeks. I found a rare part at Noels by reverse image search but they will do it for you. I've used them 3 times. Their agents are knowledgable and polite. They will find you the same part or the after market part and get you going on your way. They have 2-3 day shipping. My house was built in the 30's and they know exactly what the after market parts are that I need. I save money and time going to them. I sure wish they were in San Antonio! I will just go directly to Noel's next time - they are LEGENDS! ”
