General Pipe Cleaners high-performance nozzles increase water jet performance. They incorporate fluid mechanics to significantly increase thrust, pulling power and cleaning power without needing to increase water flow or pressure. The nozzles are custom-machined to redirect the water through efficient inner surface channels directed toward each orifice. The nozzles have replaceable threaded inserts at each orifice so when the nozzle wears, the technician only has to replace the inserts, not the whole nozzle. The penetrating Chisel Point nozzle with four forward jets and six back jets breaks up debris and hard grease deposits, and melts ice clogs. The Traction nozzle pulverizes sand and mud blockages with one forward jet and six back jets. The Cleaning nozzle has the thrust to pull the hose long distances with all eight jets to the rear. 800/245-6200; www.drainbrain.com.
