Got a leaky or stiff Kohler faucet? This Liberflow 2-pack cartridge set replaces the Kohler 1000187 (cold) and 1000188 (hot) cartridges, and it might just fix your problem without calling a plumber. These are made for deck faucets with 3/4 inch valves, so check your faucet's specs first. They're compatible with a ton of Kohler models – think K-125, K-6504, Road Kings, Street Glides, and many more (we've listed a bunch in the details). Each cartridge is built from brass and ceramic, which means they're durable, resist wear, and give you smooth operation. The ceramic discs inside provide reliable on/off control and help prevent leaks and drips, saving water and money. Installation is pretty straightforward; you don't need to be a pro. Just make sure the water's off, pop out the old cartridge, and slide this one in. It's designed to fit perfectly and restore your faucet's smooth function. Whether your handle is hard to turn or you've got a constant drip, these replacement parts can bring your faucet back to life. Keep a set on hand for quick repairs – your kitchen or bathroom will thank you!
