Straight Tube Percolator Bong | 40cm Stong Age with Removable Ash Catcher

Standing at a highly functional 40cm, this premium heavy-walled scientific pipe is engineered from high-grade borosilicate glass to deliver superior structural stability and thermal durability. The standout feature of this setup is the included high-volume removable ash catcher. 

Two-Stage Ash Catcher Core

The biggest frustration of running a large scientific setup is scrubbing stubborn resin out of the main water chamber. This 40cm Stone Age straight tube solves that problem completely by moving the initial filtration zone outside the pipe. The specialized removable glass ash catcher acts as a primary filter shield—trapping ash, tar, and debris right at the source.

 Velvet-Smooth Inhales

Engineered for unrestricted, rapid-fire clearing speeds, this straight tube features a wide 19mm female ground glass joint. This larger intake diameter expands internal volumetric capacity significantly, minimizing draw resistance so you can pull deep, effortless hits without straining your lungs.

Industrial Heavy-Wall Protection 

Blown entirely from premium, extra-thickened scientific borosilicate glass, this water pipe is built to handle the physical demands of high-frequency social settings. The bottom is anchored by an extra-thickened flat pedestal base that widens the footprint, lowering the overall center of gravity to keep the column securely planted on your table during busy gatherings.

FAQ

Q: How exactly does the ash catcher keep the main bong cleaner and save me scrubbing effort?

A: When you take a draw, the ash catcher acts as a physical security filter. As smoke pulls through the bowl, all the heavy tar, unburnt particles, and loose ash are pulled directly into the ash catcher's independent water chamber first. 

Q: What is the benefit of a 19mm joint over a standard 14mm joint on a 40cm straight tube?

A: The 19mm joint provides a noticeably wider intake channel, allowing a much higher volume of air to pass through at once. 

Q: Can I use the straight tube bong without the ash catcher attachment if I want to?

A: Yes, absolutely. Because it features a universal 19mm female ground glass joint, you can plug any standard 19mm downstem or 19mm male slide bowl directly into the main body of the bong.
