How to determine the size of the Bonza stem kit?

A Bonza stem kit consists of three main components: the stem, grommet, and cone pieces. Remember that the genuine Bonza stem has a diameter of 15mm, with the length being adjustable. All types of Bonza cone pieces and grommets fit the stem from the manufacturer. In case you want to use accessories from other brands, remember the following standard sizes:

• Stem diameter: 15mm outer, and 14mm inner;
• Grommet outer diameter (where it connects to the bong): 22mm;
• Grommet inner diameter (connects to the stem): 15mm;

After determining these sizes, to choose the right Bonza stem kit for your bong, measure the following:

• Stem total length: the total length of the metal stem;
• Stem inner length: the length of the stem inside the bong;
• Stem outer length: the length of the stem outside the bong;

Although the stem’s outer length can be adjusted, for functionality and aesthetics, it’s best to keep it within a reasonable range (10 to 20mm). The inner length of the stem is more critical and must ensure contact with the base of the bong (or higher by 5-10mm).
