Incredible functionality and diffusion from this 5mm. thick 19″ RoorTech straight tube. Featuring 45 degree joint fitting an 18mm. to 18mm. extended downstem that is set up with the Roor 18mm. built-in screen slide. The second stage filtration of the barrel perc with rock candy diffusion is second to none. The rock candy style is taking a standard slit style diffusion of most showerheads and other styles of percs and wrapping and beading molten glass over those larger openings in order to make the bubbles coming out smaller. Thus more and smaller bubbles equals more diffusion and filtration. This all is topped off by the splash guard to keep the water in the pipe.
