Combine the heavy-duty construction and materials of the premier wiper arm line with a built-in wet arm system that allows for a clean and easy installation of a washer system. A simple and easy way to keep your windshield clean, the premier wet arms feature a black PVC Hose that runs up the center of the arm and ends in a four-nozzle fixture that is an integral part of the wiper arm itself. Each solid brass nozzle is adjustable to provide a maximum coverage spray pattern for most any windshield.
