10mm, 14mm, or 18mm? How to Identify Your Bong's Joint Size and Gender

Buying a brand new quartz banger or glass bowl only to realize it does not fit your rig is incredibly frustrating. Figuring out your joint size and gender is actually very simple once you know what to look for. Here is a quick guide on how to identify your exact setup, and why SmokeMEGA clearly labels every single piece in SmokeMEGA's Best Bongs collection to ensure you buy the perfect fit the first time.

How to Measure the Joint Size (10mm, 14mm, or 18mm)

You do not need a ruler to figure out your joint size. You can easily identify it using common household items. A 10mm joint, often called a micro joint, is about the width of a standard pencil eraser. You will usually find this size on very small dab rigs. A 14mm joint is the industry standard and is about the size of a standard pen cap. SmokeMEGA curates 14mm as the primary standard because it provides the best balance of airflow and flavor. Finally, an 18mm joint is an oversized option that is almost the exact width of a dime. This size is built for massive pieces that require heavy airflow. SmokeMEGA makes shopping simple by clearly marking the sizes across SmokeMEGA's Bong Bowls collection.

Male vs. Female Joints Explained

Understanding the gender of your glass is the easiest part of the process. If the bowl goes inside the bong's joint, the bong is female. If the bowl goes over the bong's joint, the bong is male. SmokeMEGA hand-selects and clearly categorizes both styles so concentrate users never have to guess which one they need. You can easily find the right match for your specific rig by browsing SmokeMEGA's Quartz Banger & Dab Nail collection.

Frequently Asked Questions

Can I use a 14mm bowl in an 18mm bong?

No, it will not create an airtight seal. However, you can buy a cheap glass adapter that converts an 18mm joint down to a 14mm size.

What is the most common joint size for a dab rig?

The 14mm female joint is by far the most common size in the industry, which is why you see so many 14mm male bangers available.

Do I need a male or female banger for a female water pipe?

If your water pipe has a female joint, you need to buy a male banger or bowl so it can slide inside the pipe's joint.

Are silicone bongs measured the same way as glass?

Yes, silicone pipes use the exact same 10mm, 14mm, and 18mm sizing standards so you can use standard glass accessories with them.
