This component is a practical choice for keeping an older Letro cleaner in service when one worn part is holding back performance. Use it when inspection points to wear around water flow control, pressure response, and cleaner direction, or when a rebuild calls for replacing small parts that affect reliability. Part EJVW2 is intended for the L79BL cleaner family and should be selected by model, diagram reference, and the component description shown for “L79BL Cleaner 1-1/2" Wall Fitting Screen.”For best results, match EJVW2 to the cleaner parts breakdown and check neighboring wear items while the unit is open. A precise match helps protect cleaning coverage, water flow, and long-term reliability while avoiding full cleaner replacement. Supports reliable reassembly after inspection Helps maintain original cleaner function Best matched by part number before installation
