The Hemper Ninja Rig is a 7-inch (17.8 cm) borosilicate glass dab rig featuring a showerhead percolator and a built-in dab tool holder. Designed by Hemper, it filters concentrates through diffused water percolation for cooler, smoother vapour — the kind of hit that makes you wonder why you ever used a basic nail-and-dome setup. Standing at a compact height with ninja-themed decals across the body, this rig keeps your setup tidy and your sessions efficient.
The Hemper Ninja Rig measures 7 inches (17.8 cm) tall and is constructed from borosilicate glass with a showerhead percolator. Everything you need to know about what you're getting, laid out flat.

The Ninja Rig ships with the glass rig body and a standard banger, though Hemper's included components can vary by batch — check the product listing for the exact box contents. Below is a quick reference for completing your dab station when you buy the Ninja Rig.
| Item | Why You Want It |
|---|---|
| Butane torch | Consistent, even heating for your banger — essential for low-temp dabs |
| Silicone dab mat | Protects your surface and catches stray concentrate |
| Replacement quartz banger | Bangers degrade with use; a fresh one restores flavour immediately |
| Carb cap | Restricts airflow over the banger for more efficient vaporisation |
| Cotton swabs | Post-dab banger cleaning to prevent charred residue buildup |
| Isopropyl alcohol (90%+) | Weekly deep cleaning of the showerhead percolator and chamber |
Complete your dab station: pair the Ninja Rig with a quality butane torch for consistent heating, and pick up a silicone dab mat to protect your table and catch any stray concentrate. A set of replacement quartz bangers is worth having on hand too — they wear over time and a fresh one makes a noticeable difference to flavour. Browse the Hemper range and the dab accessories category at Azarius for compatible gear.
The Ninja Rig outperforms most compact dab rigs in its size bracket because it combines a genuine showerhead percolator with a practical built-in tool holder at a compact 17.8 cm height. Most dab rigs under this size do one of two things wrong: they skip proper percolation entirely, or they're so over-engineered with multiple chambers that cleaning becomes a weekend project. The Ninja Rig from Hemper hits a sweet spot — short enough to stash in a cupboard or tuck behind a monitor, but tall enough that you're not burning your eyebrows leaning into a hit.
The showerhead percolator is the real workhorse here. It sits at the base of the water chamber and forces your vapour through multiple small slits before it reaches your lungs. That diffusion cools the hit noticeably — you taste terpenes instead of just heat. We've tried rigs at this price point that use a basic downstem with no diffusion at all, and the difference in smoothness is night and day. The Ninja Rig punches well above what you'd expect.
Then there's the built-in dab tool holder. Sounds like a small thing until you've lost your third tool down the back of a sofa. Having a dedicated spot on the rig itself means your tool is always where you left it, and your workspace stays clean. It's a thoughtful touch that shows Hemper actually thinks about how people use their gear, not just how it photographs.
The main trade-off with the Ninja Rig is stability: at 7 inches tall with a relatively narrow base, it is not the piece you want on the edge of a crowded coffee table. Set it on a flat, stable surface and you're golden — but give it a knock and you'll be sweeping glass. A silicone mat underneath adds grip and peace of mind. Also worth noting: the ninja decals are printed on the exterior, so go easy with abrasive cleaners. Isopropyl alcohol and coarse salt inside the chamber work brilliantly for resin buildup, but keep the outside wipe-downs gentle. Compared to something like a larger beaker bong — such as the Blaze Glass beaker series or a standard 14-inch straight tube — you're trading raw volume and stability for portability and a more concentrated flavour profile, which for concentrates specifically is exactly what you want. Against a recycler rig like the Hemper Skull Recycler, the Ninja Rig is simpler to clean but offers less vapour recycling. Each design serves a different priority.
A showerhead percolator is a disc or flared tube with multiple slits cut into the bottom edge, positioned inside the water chamber, that breaks vapour into dozens of tiny bubbles for increased cooling and filtration. When you inhale, vapour is pulled down through the percolator and forced out through those slits into the water. This massively increases the surface area in contact with water. More surface area means more cooling, more filtration, and a smoother draw. According to harm-reduction guidance published by the Trimbos Institute, water filtration in glass pipes can cool smoke and vapour, though it does not eliminate all harmful compounds. The Ninja Rig's showerhead perc produces a satisfying churn — you can hear the bubbles stacking — without adding so much drag that you feel like you're sucking a milkshake through a coffee stirrer. The water level sweet spot sits about 1 cm above the top of the percolator slits. Too little water and you lose the filtration benefit; too much and you get splash-back. Fill it, take a dry pull without heating anything, and adjust from there.
Using the Ninja Rig takes six straightforward steps, from filling the chamber to post-session cleaning. Follow the sequence below for the best results each time you order a session with your concentrates.
