The Stundenglass Large Upstem is a diffuser downstem that is part of the Stundenglass Gravity Pipe. It is located inside one of the globes of the pipe and filters smoke through water as the bong is rotated. The Upstem is essential for the functionality of the gravity bong. If you have a broken Large Upstem or simply want replacements, this accessory is for you. It is compatible with the traditional Stundenglass Gravity Pipe.
The Large Replacement Upstem is made of aircraft-grade aluminum, making it durable and long-lasting. It is also easy to install and use. The design of the Upstem is patented, ensuring its uniqueness and quality.
For those who have the Small Globes Kit or the smaller Stundenglass Kompact Gravity Pipe, there is a Small Upstem available for purchase separately.
Overall, the Stundenglass Large Replacement Upstem is a necessary accessory for those who own the Stundenglass Gravity Pipe and need a replacement or want to have extra Upstems on hand. Its high-quality construction and patented design make it a reliable and efficient component of the gravity bong.
