Grav® Adjustable Downstem

Whether you're tired of trying to measure broken downstems, or perhaps just prefer different water levels in your bong, the Grav Adjustable Downstem is here to save the day! This unique adjustable downstem from Grav can extend anywhere from 4" to 6" inches in length and is compatible with any 18mm joint beaker bong or straight-based water pipe with a 45° joint angle. It’s an 18mm-to-14mm replacement downstem meaning it will fit within an 18mm water pipe joint while providing a 14mm female at the top for your bowls and accessories. The Grav Adjustable Downstem features a tri-cut showerhead diffuser that expertly filters your smoke through water, and the two halves of the downstem are held together by a custom fitted segment of heat shrink tubing.
