MILK GLASS DOWNSTEM
Our Milk Glass Downstem is a borosilicate glass replacement downstem for water pipes. This model uses an 18mm ground joint with a 14mm female inside opening for the bowl, and it comes in 5, 5.5, and 6 inch lengths.
Choose the length that matches your piece, then pick from Milk Blue, Milk Purple, Milk Pink, or Milk Green. The frosted milk-glass look and diffusion slits give this downstem a more distinctive finish than a basic clear replacement while keeping the buying decision focused on fit.

How Do I Match This Milk Glass Downstem to My Bong?
Fit comes first with any replacement downstem. Match the 18mm ground joint to your water pipe, make sure your bowl works with the 14mm female inside opening, and measure the downstem length before ordering. The correct length should let the lower diffusion section sit in the water without the stem contacting the bottom of the piece. Our downstem sizing guide walks through the measurement basics.
What Do the Diffusion Slits Do?
The lower slits route smoke through the water as bubbles instead of sending it straight out of an open tube. For this product, the practical point is simple: keep the slit section submerged when you set the water level so the downstem can perform its filtration role.
How Should I Clean the Milk Glass Downstem?
For routine buildup, remove the downstem and clean it in a sealable container with coarse salt and 91% or higher isopropyl alcohol. Shake gently, then rinse thoroughly with warm water and let the piece dry before reinstalling it. Avoid forcing the glass into a joint that does not match.
