KR-A General Wire Kinetic Water Ram without Carrying CaseThe Kinetic Water Ram uses a burst of compressed air that drives a shock wave (kinetic energy) through water to break up stoppage. It's particularly useful when the stoppage is on the far side of a drum trap or series of tight bends, since the shock wave can travel around bends without losing its force.Features: Compact, light weight tool for quickly opening clogged sinks, toilets and tubs Handles rust, grease, sediment, and scale in lines up through 4" in diameter Self-contained pump and pressure gauge Hit the stoppage with just the right amount of force Get instant impact with no build-up of pressure in the plumbing system The force is transmitted through water, so it's not affected by stacks or vents Specifications: 16 gauge plated cylinder tested for up to 600 lbs, pressure 160 lbs. gearless pressure gauge provides pinpoint pressure control Built-in air compressor easily pumps up to desired pressure Flexible cone seals drains ranging from 1 1/4" to 4"diameter Equipped with Schr der valve for use with external air compressor when clearing difficult stoppages KR-A Includes: Kinetic Water Ram, Complete with Extension Hose, 4" Rubber Cone, and Five Rubber Plugs.
