Adapters save time and money by unlocking more combinations from the glass you already own. Whether you’re pairing a favorite 14 mm bowl with an 18 mm male-jointed rig or testing a new attachment, this reducer keeps the connection secure and the draw smooth.

• Fully seat both joints before clipping on any keck clip to protect the ground glass.
• Keep flame away from the adapter; allow hot glass to cool before removing.
• Clean with a glass-safe cleaner, then rinse with warm water for a perfect fit.
