14mm Female to 18mm Male Glass Adapter
14mm Female to 18mm Male Glass Adapter
This premium 14mm female to 18mm male glass adapter (also commonly called a reducer or expander) is an essential accessory for any dab rig, bong, or water pipe collection. It bridges the gap between different joint sizes, letting you attach 14mm male accessories (like quartz bangers, herb bowls, or nails) to an 18mm female joint on your main piece — or expand a smaller setup to accept larger components.
Key Features:
- Precision Ground Joints: One end features a 14mm female joint and the other a robust 18mm male joint, both expertly crafted for a tight, leak-free seal and optimal airflow.
- High-Quality Borosilicate Glass: Constructed from thick, durable borosilicate glass that resists thermal shock from torches, e-nails, and high-heat dabbing sessions.
- Compact & Stable Design: Low-profile build (typically 2–2.75 inches tall) adds minimal height while keeping your rig balanced and stable during use.
- Versatile Joint Conversion: Easily converts an 18mm female connection down to 14mm or allows you to use larger 18mm male pieces on smaller setups.
- Attach your favorite 14mm male bangers or bowls to an 18mm female dab rig or bong.
- Expand a 14mm male piece to fit into an 18mm female joint.
- Customize and upgrade your current glass collection without buying new rigs.
- Combine mismatched glass pieces for improved filtration, recyclers, ash catchers, or multi-chamber setups.
