Amsterdam Downstem with 4-Arm Diffuser - 29,2mm / 11cm

Amsterdam Downstem with 4-Arm Diffuser - 29,2mm / 11cm

This Amsterdam model combines a downstem's function with a four-arm diffuser tip. This design directs the flow through several arms, while the stated dimensions help you choose a component that fits your bong and separate bowl.

The lower section of the downstem forms a four-arm diffuser. Instead of directing flow through only one outlet, the design distributes it across several points. This is the model's key functional feature and distinguishes it from a simple downstem with a single opening.

The 11 cm length determines how far the component reaches inside the bong's body. When fitted correctly, the downstem should sit at the appropriate depth without the diffuser resting on the bottom.

This model requires consideration of two different connections: 29,2 mm on the bong side and 18,8 mm on the bowl side. These values are not interchangeable—each describes a different attachment point. Before buying, compare the diameter of the bong's connection, your bowl's joint, and the length of your current downstem.

The downstem therefore suits a setup that matches all three specifications: a 29,2 mm connection, an 18,8 mm bowl, and an 11 cm length. This reduces the risk of choosing a component that looks right but has unsuitable dimensions.

Use and cleaning

The diffuser's four arms create more crevices than a simple tip, so remove buildup regularly. Remove the component without forcibly twisting it, and rinse and dry the joint surfaces thoroughly before reinstallation. Careful handling is especially important when removing the downstem from a tight connection.
