Main Feature: Multiple Joint Size Conversions

The main feature of these glass adapter grommets is the ability to convert between common bong and dab rig joint sizes. They are designed for customers who need to size up, size down or connect compatible accessories that do not naturally fit together.

Available Adapter Options

• 10 mm Male to 14 mm Female: Helps compatible 10 mm rigs or pieces accept 14 mm male accessories.
• 14 mm Male to 18 mm Female: Useful when upgrading compatible setups to accept larger 18 mm male accessories.
• 14 mm Female to 18 mm Male: Helps adapt smaller compatible connections for 18 mm female bongs, rigs or downstems.
• 18 mm Female to 14 mm Male: Reduces compatible 18 mm setups for use with matching 14 mm female connections.

Borosilicate Glass Construction

Borosilicate glass is a strong choice for bong and dab rig accessories because it handles heat well, looks clean and is easy to inspect after use. The clear glass design makes these adapters easy to match with most glass water pipes and concentrate setups.

Frosted Ground Joints for a Secure Fit

The frosted ground joint style helps create a snug connection when paired with the correct matching size and gender. This is important for airflow, accessory stability and everyday setup comfort.

Who Is This For?

These glass adapter grommets are best for bong owners, dab rig users, bowl piece shoppers and glass accessory collectors who need better compatibility across different joint sizes.

They are especially useful for customers who own more than one glass piece and want to keep using favourite bowls, bangers, nails, downstems or accessories without replacing the full setup.
