It's the fixed teeth that give this Viper its name, along with the fiberglass strands that make it strong and durable – far more than any conventional plastic nozzle. Made of composite material with brass internal stems, these nozzles shut off past a straight stream and fog position. Their burst point is about 930 P.S.I. with a melting point of around 250 degrees. Weight: 10.5 oz. Length: 5-¼". 95 gpm, 1-½" N.S.T. Rigid Base.
