Alex K Showerhead Downstems are Aqua Lab's best-selling replacement downstem and have been a staple bong accessory in our store for many years. These glass downstems add a high-functioning percolator to any bong or water pipe. Alex K downstems fit most standard bongs, bubblers, and water pipes requiring a 14/18mm fitting. The 14/18mm showerhead downstems feature quality boro glass and several diffusion slits for added airflow and superior water filtration. Alex K replacement downstems are handblown in Arizona from a quality, American borosilicate glass.
After using straight cut down stems for who knows how long I wanted to try something different. I learned about "showerhead" down stems and came across Alex K and lo and behold Aqualabs carried them! It works wonderfully and is a semi-ash catcher too!
This has been my first diffusing downstem and it’s been amazing. Much better filtration over a stranded stem and allows for bigger smoother hits. With that being said there are much better stems out there for not too much more money. Make sure you measure correctly for your piece
