Frozen Glycerin Bong Downstem 18mm to 14mm by CaliOtter Glass

The Ultimate Chill. Add a cooling upgrade to your setup with this glycerin downstem. It features a glass exterior filled with premium glycerin and functions like a standard downstem, with a chilled chamber designed to help lower the temperature as it passes through.

How it Works: Place the downstem in the freezer for about an hour before use. Since glycerin freezes at a lower temperature than water, it becomes very cold without freezing solid or expanding, helping reduce the risk of cracking. The chilled chamber is ready to use once it has been frozen and installed.

Long-Lasting Cooling. Unlike ice that melts over time, glycerin stays cold longer for repeated use. For best results, store it in the freezer after cleaning so it is ready when needed.

Universal Compatibility. This downstem uses a standard 18mm to 14mm joint. It fits any 18mm (or 19mm) female bong opening and works with 14mm male bowls or bangers. It is a common size for many glass bongs, making it a practical replacement or upgrade option.

*To ensure a proper fit, measure your current downstem from the bottom of the frosted joint to the very tip.
