Slides & Bowls

Slides and bowls are among the most frequently replaced components in any bong setup, making quality options an important part of daily use. A well-designed slide affects airflow, burn rate, and how easily a bowl snaps, while factors such as bowl size, hole configuration, and handle style influence how flower packs, burns, and clears. Many users keep multiple slides on hand to suit different pieces and session preferences. Joint size determines compatibility. Most slides are made with 14mm or 18mm male joints, which are standard across scientific and heady glass. Some smaller or older pieces use 10mm joints, while the choice between 14mm and 18mm often comes down to bong design and personal airflow preference. Selecting the correct joint size ensures a proper seal and consistent function. Hole count and placement play a major role in how a slide performs. Single-hole bowls offer simplicity and help prevent pull-through, while multi-hole slides distribute airflow more evenly and catch ash before it enters the downstem. Some designs incorporate built-in screens or gridded patterns for improved airflow and debris control. Handle styles range from simple nubs and marbles to worked horns and sculptural elements that add grip and visual character. Slides are often used interchangeably across different pieces, especially when joint size is compatible. At the same time, many collectors choose to match slides to specific tubes based on visual accents and overall presentation. Clear bowls are commonly paired with clear tubes, while accented slides featuring color, millies, or fuming are often selected to complement worked or accented glass. Artist-made slides can also become collectible in their own right, with limited runs, collaborations, and one-off designs valued for their craftsmanship and connection to a particular artist or era.
