Bong Gromnets for a Snug Fit and Smoother Pulls

The Bong Shop stocks bong gromnets that help seal the join between your stem and the bong body, so you don’t deal with wobbles or air leaks. You’ll see rubber and silicone options, plus singles and multi-packs for quick replacements. Our bong accessories are tiny, but they matter a lot when you’re swapping stems, bowls, or mixing parts.

How do you pick the right size grommet?
Start by checking what you’re fitting it into: the hole on the bong and the piece you’re pushing through it (usually the downstem). If you’ve got a Bonza-style setup, look for Bonza-specific options instead of guessing with “standard” sizes. When you’re unsure, measure the hole and compare it to the product details, then size up slightly if you’re sitting between two options. A grommet that’s too loose can wobble; too tight can be a pain to install.

How do you replace bong gromnets without ripping them?
Warm water helps soften rubber or silicone before you fit it, especially if the old one has gone stiff. Use clean fingers and a tiny bit of water-based slip (even a damp fingertip) rather than forcing it in dry. If you’re pushing a stem through, twist gently as you go instead of shoving straight down. Once it’s in, give everything a quick check for cracks or rough edges around the hole, because that’s what usually chews up new bong gromnets.
