While the downstem that came with your bong is an important part of your water pipe, if it’s made of glass it can crack or break. That’s why it’s a good idea to switch out your glass downstem with one made of super durable silicone like this piece from Entropy Labs.
This colorful downstem is constructed from food-grade silicone, making it virtually unbreakable. The downstem features a 18.8mm>14.5mm male joint, making it compatible with most female-jointed water pipes.
This durable, flexible, heat-resistant downstem features diffusion holes to smooth the smoke. It’s available in numerous lengths and multiple colors so finding the exact size and color you need should be easy.

Worked Perfectly
To be honest I didn't even know what size I needed so I guessed but it worked for exactly what I needed it for.
Happy customer
I highly suggest this particular silicone product if, like me, you’re tired of breaking glass down stems. The diffused end allows for a smooth pull. Maybe not as smooth as the glass stem it replaced, but close enough. True to size, fits my piece nice and snug. Make sure to properly size this product before purchasing, instructions can be found on the website using the search feature (I did not see a link for instructions on the product page). Received my order within a week.
