Swap in a White Rhino 19/14mm glass downstem and give your bong a fresh, airtight fit that drops right into a 19 mm joint while holding any 14 mm bowl slide. Each stem is precision-cut from borosilicate glass for extra heat resistance, with diffusion slits at the tip that break smoke into fine bubbles for a cooler, smoother pull. Choose the perfect length—3-6"—to match everything from compact beakers to tall straight-tubes, and keep an extra on deck so a clumsy knock never ends the sesh.

• Length options: 3", 3.5", 4", 4.5", 5", 5.5", 6" measured from joint bottom to diffuser

• Material: Thick borosilicate glass resists heat and minor bumps

• Diffuser style: Multi-slit tip for improved smoke cooling

• Purpose: Direct replacement or backup downstem for 19 mm bong joints
