Wagner spray nozzle seal set for the Control Pro HEA range 250 M, 350 M, 250 R and 350 R. The Wagner HEA seal set is suitable for the spray nozzle of the HEA paint gun (hybrid and metal versions). The seal is located at the front of the gun, just behind the spray tip. This ensures that the spray tip stays firmly in place and no paint leakage can occur. This seal is necessary to maintain constant pressure and achieve a good spray pattern.
