3/4" WH Warthog Classic Rotary Nozzles

When you're running higher-flow jetting equipment, you need a nozzle that can keep up. The Warthog® WH Classic 3/4" has been a trusted choice for professional sewer cleaning crews since 1990, delivering reliable, high-impact cleaning performance in some of the toughest applications.

Designed for cleaning 6"–36" sewer lines, the WH Classic uses Warthog's proven Controlled Rotation Technology to cut through grease, sludge, roots, scale, and stubborn deposits while providing consistent wall-to-wall pipe cleaning.

Built for jetters producing 30–50 GPM, the 3/4" WH Classic is an excellent fit for combination trucks, trailer jetters, and large truck-mounted systems. Whether you're maintaining municipal infrastructure or handling demanding commercial and industrial jobs, this nozzle is built to deliver dependable results shift after shift.

Available Configurations

Standard Configuration

The Standard configuration features two rear jets and one front coring jet, making it the go-to choice for routine sewer cleaning and preventative maintenance.

Its balanced jetting pattern provides excellent cutting, pulling, flushing, and overall cleaning performance across a wide range of pipe conditions. Combined with its durable, rebuildable construction and redesigned centralizer, it's built to provide reliable service for years to come.

Descaler Configuration

For heavy scale, mineral deposits, and hardened buildup, the Descaler configuration delivers extra cleaning power where it's needed most.

Featuring two additional center descaler jets, this configuration directs greater force through the side jets while positioning them closer to the pipe wall for increased cleaning impact. The result is faster, more aggressive descaling and improved polishing of the pipe interior.

The Descaler model also includes convenient access ports for fluid changes without disassembly and a rugged 4-fin cast unibody design that allows steeper rear jet angles for improved pulling power, flushing performance, and reduced hang-ups while navigating the pipe.
