Replacing old, leaky faucet connectors? This set of two 20-inch stainless steel supply lines is a universal upgrade. They have standard 1/2-inch IPS (Iron Pipe Size) threads on one end to connect to your shut-off valve, and a 3/8-inch OD (Outside Diameter) compression fitting on the other end for your faucet. The braided stainless steel exterior is durable and resists kinking, while the inner tube is designed for safe drinking water. They're unbranded but built to handle standard household water pressure. Perfect for installing a new kitchen or bathroom faucet, or as a preventative replacement for worn-out rubber hoses. Always a good idea to use quality lines to avoid potential water damage. A basic, essential plumbing part for any DIYer or professional.
