Danco Assorted O-Ring Kit, 200-Pieces is a comprehensive set designed to help you easily repair leaky faucets. This kit includes 200 O-rings that serve as seals on faucet stems, ensuring a tighter and more effective seal to prevent water leaks. Faucets often use one or more O-rings to stop water from escaping around the spout, but over time these O-rings can wear out or get damaged, causing leaks. With this kit, you can replace worn O-rings and restore your faucet's functionality without the need to replace the entire fixture, making it a practical and cost-effective solution.
