The WV-1/4-LK uses StoneAge’s flow-through technology and features a revolutionary high-speed rotating design with no high pressure seals or bearings to service. It cleans lines as small as 2” (51 mm) with long sweeping elbows. The head design also features permanent, pre-drilled orifices rather than threaded nozzles.

The tool has a 1/4” NPT pipe thread inlet and can pass hrough long radius elbows in lines 2” (51 mm) and larger if a 1/4” NPT hose fitting is used.
