How To Select Your Glass Joint Size & Type

Posted by Elev8 Presents on 12/2/2019

Is the ground glass joint 10mm, 14mm or 19mm?  Is it male or female?

Here at Elev8 Glass Gallery we hear over and over, what size joint do I have?  This is a very common question that most every one has at some point in their life.    The good news is we have the answers that will help you.  Below is an image that shows a great way to see what size and style joint you have.  

Know what size ground glass joint you have

19mm (18.8) Female Glass Joint-
This is the largest of the standard joint sizes used in the industry.    These joints are used on many water pipes that have a downstem.  This is so that you can have a nice large downstem and have what we think is the perfect size joint for your bowl.  This 19mm male joint fits perfectly with a 19mm male joint.  The joint is about the size of a quarter.

14mm Female Glass Joint-
This is the middle standard female joint size.   This is the most common glass joint size for rigs and water pipes that do not have a removable down stem.  A 14mm-10mm downstem is what is used in this joint if you have a removable downstem.  The joint is about the size of a nickle.  

10mm Female Glass Joint-
This is the baby joint and is mostly used on mini rigs and small water pipes.   There is no downstem that can go into this and only works with a 10mm male joint.  The joint size is about the size of a dime.

19mm (18.8) Male Glass Joint-
This male joint fits the 19mm female joint and is the largest of the standard male joints in the industry.  The joint size is about the same as a dime

14mm Male Glass Joint-
This male joint is the most common male joint in the industry.  Most bowls are this because they usually go into a 19mm downstem that transition to a 14mm female.  This joint size is about 20% smaller than a dime

10mm Male Glass Joint-
This male joint is the most common male joint in the industry. Most bowls are this because they usually go into a 19mm downstem that transition to a 14mm female. This joint size is about 60% smaller than a dime

18mm Glass Joint- There is just no such thing.  In math one uses the rounding rule.  Because this joints actual measurement is 18.8mm, the joint is rounded up to 19mm.  Anyone that says 18mm is ignorant to the correct size of the joint and should be corrected to prevent further bad information in the world.

Using some coins you might have in your pocket will help easily identify what size joint you have an type.

Male joints go into the female joint.
