The Avagard Drain Blaster is a heavy-duty solution for high-pressure drain cleaning. Crafted from tough and corrosion-resistant heat-treated 303 grade stainless steel, this nozzle is built to withstand the toughest cleaning tasks. With a 3/4-inch female hose thread inlet, it's compatible with various hose setups for versatile use. Ideal for cleaning 4-inch to 6-inch drains, catch basins, sidewalks, or cart paths, it operates effectively at a minimum water pressure of 70 PSI. The two-stage flushing action ensures efficient removal of dirt and debris, while the front jets cut through blockages and the rear jets propel the nozzle upline. Plus, with a wire attachment connector, you can use a wire locator to determine the drain route with ease. Professional-grade and long-lasting, the Avagard Drain Blaster is your go-to tool for effective drain cleaning.
