Before buying a replacement bowl or shooter, check your bong's joint size and connection type. Measure the connection, not the bowl width or bong height.

For size and joint-type matches, see the full 14mm vs 19mm compatibility table.

Joint Size at a Glance

• 14mm and 19mm are common bowl and shooter joint sizes. Check your product specification rather than assuming.
• Record whether the joint is male or female as well as its size.
• Measure the correct point on the joint, then compare with the manufacturer's specification.

Male and Female Joints

• Female joint: an opening that accepts a male bowl or shooter.
• Male joint: a protruding connection that a female bowl or shooter fits over.

How to Measure Your Bong Joint

1. Clean and dry the joint. Let the piece cool, empty the water and remove the bowl carefully. Residue can affect the reading.
2. Check existing specifications. Look for the joint size in the original listing or markings on an accessory that already fits. Note any installed adapter.
3. Identify the connection. Record male or female, then locate the tapered section where the accessory seats.
4. Check where to measure. Follow the manufacturer's joint-measurement guide. A tapered joint has different diameters along its length.
5. Take the measurement gently. A ruler gives an approximate reading; a caliper is more precise. Do not squeeze or lever against glass.
6. Compare and record. Confirm the nominal size and joint type against the product specification. If the reading is unclear, send TBBC support a photo with a ruler for scale.

Common Measuring Mistakes

• Measuring the bowl rim or mouthpiece: measure the mating joint instead.
• Choosing by bong height: a taller piece does not necessarily have a larger joint.
• Reading an arbitrary point on the taper: check the manufacturer's measurement point.
• Missing an adapter: distinguish the original joint from the connection on an installed reducer.
• Rounding an unclear reading: confirm the specification rather than guessing between sizes.
• Pressing tools against glass: measure gently and never force an accessory in as a size test.

FAQs

Can I measure a bong joint with a ruler?

A ruler can give an approximate reading. For greater precision, use a caliper gently at the measurement point specified by the manufacturer.

Why does the diameter change when I move the caliper?

The joint is tapered. Its diameter changes along its length, so readings from different points are not directly comparable.

What should I do if my measurement is between 14mm and 19mm?

Check the measurement point, original specifications and any adapter. Send TBBC support a clear photo with a ruler for scale if the size remains uncertain.

After confirming the measurement, check the stated specifications in Bowls & Shooters. Complete your setup with Herb Grinders & Herb Crushers.
