Replacement Downstem 3.75"

Even if you have a very durable bong made of thick glass, you still should have a spare downstem on hand. The downstem is a piece you handle often and clean regularly, which puts it at risk for breakage. 

This 3.75-inch long glass diffuser downstem features a 18.8mm male to 14.5mm female joint, making it compatible with 18.8mm female-jointed water pipes. 

Whether you broke or misplaced the original downstem that came with your bong, or simply want a spare, this diffuser downstem will serve you well for a long time. It features a classic 6-cut style found on most bongs.
