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 ensure a reliable seal at each connection point.This 4-foot washing machine water inlet hose set is constructed with ultra-high tensile strength braided stainless steel, a dual-layer PVC core, and reinforced nylon wire in the middle, ensuring durability, leak resistance, and burst protection. Designed to resist kinking, crimping, and corrosion, these hoses perform well in both high and low temperature conditions. The 4-foot braided stainless steel water supply lines are compatible with most washing machines and can be easily connected to standard household water supply valves. Both hoses are stainless steel braided for flexibility and ease of installation in tight spaces.Installation is simple and does not require a professional. First, disconnect the old hose from the water supply valve. Attach the new water supply hose to the water supply valve, then connect the other end to the corresponding hot or cold water inlet on the washing machine. Hand-tighten both connections to ensure a secure fit.
