Each package includes 1 red-colored washer hose for hot water and 1 blue-colored washer hose for cold water. Each hose features a 3/4-inch female hose thread x 3/4-inch female hose thread connection. The 3/4-inch NPT connections on both ends provide a secure fit for your washing machine and water supply valves. Extra-thick rubber washers help create a reliable seal at each connection point.The 4-foot washing machine hot and cold water hoses are constructed with ultra-high tensile strength braided stainless steel, a dual-layer PVC core, and reinforced nylon wire in the middle. This design ensures durability, leak resistance, and protection against kinking, crimping, and corrosion. The hoses are suitable for both high and low temperature water applications. Compatible with most washing machines, these supply lines easily connect to standard household water valves in the laundry area. The stainless steel braiding allows for smooth installation, even in tight spaces.Installation is simple and does not require a professional. Begin by disconnecting the old hose from the water supply valve. Attach the new hose to the water supply valve, ensuring a snug fit. Then locate the hot and cold water inlets on the washing machine and hand-tighten the corresponding ends of the hoses to the proper inlets.
