Collection Ash Catchers UK | 14.5mm & 18.8mm Glass Pre-Coolers

Ash catchers are one of the simplest ways to keep your bong cleaner for longer. By catching ash and debris before it reaches your main chamber, they help reduce cleaning time while keeping airflow smoother and more consistent.

 At A Bong Shop, we stock practical 14.5mm and 18.8mm glass ash catchers designed to fit most standard UK setups. Choose from dry ash catchers for straightforward protection, or percolator ash catchers for added diffusion and cooler pulls.

Not sure which size you need? Most UK bongs use 14.5mm (often called 14mm) or 18.8mm (18mm) joints. If you’re unsure, check your bowl size or browse our full range of bongs and bowls to confirm compatibility.

If you want to keep your setup cleaner and smoother, an ash catcher is one of the most effective upgrades you can add to any bong. 👉 For the perfect bong
