Upgrade your setup with a 5.75 inch 8 slit downstem designed for smoother, cooler hits and more consistent filtration. Made from durable borosilicate glass, this diffused downstem uses eight precision-cut slits to break smoke into smaller bubbles for better smoke-to-water contact. It is an easy replacement or upgrade for compatible beaker setups that use a 19mm female joint and 14mm bowl connection.
