Kohler Part GP876851 Rite-Temp Mixer and Pressure-Balancing Unit Kit, SINGLE, Black

The Kohler website has information on identifying specific valves and a helpful video on replacement installation. I have a K304 valve fitting and this kit fit perfectly in my 10-year-old faucet. The PBU was redesigned so it did not look like my old discontinued unit but it fit just fine. The mixer looked identical to my old unit. I would recommend going with genuine Kohler parts vice cheaper imported knock-off units. In either case, this fixed my small leak. The only negative is the kit includes a very small amount of lubricant but I managed to stretch it out. The kit is designed to repair several variants of shower fixtures and you'll have extra washers after the install.

la marca lo dice todo excelente

We had a leaking bathtub faucet , went to a hardware store to find out they don’t sell parts for Kohler bathtub faucets, so instead of ordering the parts from their website and wasting a lot more money , we decided to order from Amazon for way cheaper. It’s been about 3 weeks or so and it’s been working perfectly ! No leaks, no sounds of running water like our old parts did. If I can rate more than 5 stars I would. Very easy to install too

My 15-yr-old Kohler mixer valve sprung a leak, so I order this to replace it. I was very surprised that it fit absolutely perfectly! The directions are clear and the installation went very smoothly and the whole job took less than 30 minutes beginning to end. I highly recommend this product.
