Say Goodbye to Messy Cleanups – Grab Yours Now!

he 4-Slit Removable Ash Catcher is a simple upgrade that makes a noticeable difference to your setup. By catching ash and debris before they reach your bong, it helps reduce buildup, improve cleanliness, and make regular maintenance easier. Its removable downstem also makes rinsing and deep cleaning much more convenient than fixed-piece designs.

Ash Catcher details

Removable Downstem

A removable downstem makes maintenance quick and painless. Just detach it for easy rinsing and deep cleaning. This keeps your hits smooth and your ash catcher clean.

Traps Unwanted Ash

Catch ash and debris before they reach your bong. By trapping ash in its own chamber, this ash catcher ensures cleaner hits, reduced buildup, and less frequent deep-cleaning of your bong.

Cools Smoke

Experience smoother, more refreshing hits as this design diffuses and cools smoke. By cooling the smoke before it reaches you, you’ll enjoy enhanced flavor, reduced harshness, and a more comfortable bong hits.

4-Slit Percolator

This ash catcher's percolator features slits that work in harmony to break up and diffuse smoke, ensuring smoother hits.

Fit & Compatibility

This ash catcher uses a 14mm male-to-14mm female connection and is designed for compatible setups that need a cleaner, easier-to-maintain smoking experience. If you use a Castle beaker bong, this is built to pair with that style of setup. Before ordering, confirm both your joint size and joint angle so you get a secure fit and proper bowl position.

How to check fit:

Confirm your bong’s joint size is 14mm female

Confirm whether your setup needs a 45° or 90° ash catcher

Make sure your bowl matches the ash catcher’s receiving joint

Designed for buyers who want dependable function without overpaying for hype

How to Use, Fill, and Clean It

Attach the ash catcher to your compatible bong, then add just enough water to submerge the slits on the downstem. Too much water can cause splashback; too little reduces filtration. After use, remove the downstem for a quick rinse or deeper clean.

For deeper cleaning, use a glass-safe cleaning solution, rinse thoroughly, and allow all removable parts to dry fully before reassembly. Regular cleaning helps preserve flavor, airflow, and overall performance.

FAQs

What does the 4-slit percolator do?

The 4-slit downstem helps diffuse smoke into smaller bubbles, which can make hits feel cooler and smoother.

Do I need a 45° or 90° ash catcher?

That depends on your bong’s joint angle. Beaker bongs commonly use a 45° ash catcher, while straight vertical setups often use 90°.

Yes, it will fit all Castle Glassworks beaker bongs. Please note that we cannot guarantee compatibility with non-Castle Glassworks bongs.

What’s The Ideal Water Level?

Just enough to submerge the slits on the downstem—too much can cause splashback, too little reduces filtration.
