How to Replace a Bong Bowl: Sizes Explained

A broken bowl is the most common replacement part there is — and the easiest one to get wrong if you guess at the size. Here's how to get it right.

1. Find your joint size

The bowl slides into the downstem (or straight into the piece), and the two sizes you'll run into are 14mm and 19mm. If you still have the old bowl, match it. If you don't, look at the downstem it sat in: a 14mm downstem joint takes a 14mm bowl, and a 19mm joint takes a 19mm bowl. Same rule as downstems — the bowl and the joint it slides into have to be the same size.

2. Get the gender right

A male bowl slides INTO the downstem. A female bowl receives the downstem. Most bowls people replace are male — they slide into a female joint on the downstem — but check yours before ordering. The wrong gender won't fit no matter how right the size is.

3. Pick your style

The two styles most people ask for are screen bowls and push bowls. Screen bowls hold a small screen that keeps herb out of the stem; push bowls have a built-in glass screen, so there's nothing extra to buy or lose. Either way, size and gender come first — style is just preference.

Measure twice, order once

If you're not sure, measure the opening the bowl slides into rather than the bowl itself — broken glass is hard to measure straight. And if your old bowl was a 14mm screen bowl, order a 14mm screen bowl. Replacing like-for-like is the safest move there is.
