Dealing with a drippy faucet? Before you call a plumber (and empty your wallet), check out this DANCO replacement stem. Specifically designed for Milwaukee and Universal Rundle faucet models like K6380, K6240, 86381-2, and 86240-2, this cold water stem is an affordable fix that'll have your faucet working like new in no time. Made from durable plastic that's built to last, it comes with a bonnet included so you have everything you need for the repair. The ID length is 4 with an S broach configuration - if that sounds like technical jargon, don't worry, just match it to your old stem. What's important is that this product complies with the Reduction of Lead in Drinking Water Act, so you don't have to worry about contaminants in your water. I replaced mine last weekend, and the process was straightforward - turn off the water, remove the handle, swap the old stem for this new one, and reassemble. No more annoying drip-drip-drip sound driving me crazy at night! The plastic construction might not sound as fancy as metal, but it's actually more corrosion-resistant and works perfectly for cold water applications. The fit was exact, and everything sealed up nicely without any leaks. If you're not sure whether this is the right part for your faucet, just check the model number or bring your old stem to the hardware store to compare. For less than the cost of a service call, you can fix that leak yourself and feel that satisfaction of handling your own home maintenance. Plus, stopping that constant drip saves water and money on your utility bill. It's one of those simple repairs that seems intimidating but is actually totally doable for most homeowners.
