Kube Silicone Oil Bong by PieceMaker
The Kube Silicone Oil Bong is a cube-shaped silicone dab rig by PieceMaker that doubles as its own carry case. Built from food-grade silicone with a stainless steel base, it packs flat for travel and reassembles in seconds — every component slots into the body when you're done. If you've ever tried to transport a glass oil rig and winced at every bump in the road, this is the fix.
What Makes the Kube Silicone Oil Bong Worth It
Most oil rigs are fragile. Glass-on-glass joints, thin downstems, wobbly bases — they're built for the coffee table, not for a backpack. The Kube takes a completely different approach. PieceMaker designed it from medical-grade silicone that flexes on impact instead of shattering. The cube shape isn't just for looks (though it does look properly unusual sitting on a shelf). It's functional: the flat top surface has individual recessed slots for the L-shaped glass downstem and bowl, the included dab tool, and PieceMaker's "Kontainer" — a small silicone pot for storing your concentrates. Everything has a home.
Pick it up and you'll notice the weight sits low. That's the removable stainless steel base plate doing its job — it keeps the Kube planted on whatever surface you set it on, and when you're packing up, it unscrews to become a storage compartment. The mouthpiece, downstem, bowl, dab tool, and Kontainer all nest inside the body. Screw the base back on and you've got a sealed, self-contained unit roughly the size of a large Rubik's cube. No separate pouches, no bubble wrap, no anxiety.
The one thing to keep in mind: this is a silicone piece with a glass downstem. The silicone body is virtually indestructible, but that glass L-shaped downstem and bowl are the weak link. Handle those two parts with the same care you'd give any glass joint. PieceMaker includes them because glass preserves flavour better than silicone for the actual vapour path — a smart trade-off, but worth knowing about before you toss the whole thing into a rucksack without padding.

Why a Silicone Oil Bong Beats Glass for Travel
We've sold glass oil rigs for years. They look beautiful, they hit clean, and they break. Not sometimes — regularly. A customer walks in, buys a gorgeous borosilicate rig, and two weeks later they're back because it rolled off the desk or got knocked in a bag. That's the reality of glass.
Silicone changed the game for anyone who moves their gear around. Drop the Kube off a table and nothing happens. Squeeze it into a packed bag and it flexes back to shape. The cube geometry actually helps here — flat sides sit flush against other items instead of rolling around like a cylindrical bong would. And because PieceMaker engineered the storage into the base, you're not carrying 5 loose pieces wrapped in socks. It's one sealed unit, roughly 10cm per side.
The trade-off? Silicone doesn't have the visual clarity of glass, and purists will tell you flavour is marginally different through a silicone chamber versus borosilicate. They're not wrong — but PieceMaker addressed the flavour concern by using a glass downstem and bowl for the actual vapour path. The silicone handles structure and durability; the glass handles taste. It's a sensible split. For a dedicated home setup where the rig never moves, a full glass piece might edge it on aesthetics. For anything involving a bag, a car, a festival, or flatmates who knock things over, the Kube is the smarter pick.
How to Use the Kube Silicone Oil Bong
- Unscrew the stainless steel base from the bottom of the Kube and remove all stored components: mouthpiece, glass L-shaped downstem and bowl, dab tool, and Kontainer.
- Screw the base back onto the bottom of the Kube to give it a stable, weighted platform.
- Insert the glass L-shaped downstem into the designated port on the side of the cube. Attach the glass bowl to the downstem.
- Press the silicone mouthpiece into the top opening until it sits snug.
- Fill the Kube with water through the mouthpiece opening before inserting the mouthpiece — add just enough so the bottom of the downstem is submerged by about 1-2cm. Too much water and you'll get splashback.
- Use the included dab tool to load a small amount of concentrate from the Kontainer onto the bowl or nail.
- Heat the bowl with a torch, allow it to cool for a few seconds to the right temperature, then apply the concentrate and inhale through the mouthpiece.
- After your session, pour out the water, disassemble all parts, and store everything inside the Kube body. Screw the steel base on to seal it up for transport.
Cleaning Your Silicone Oil Bong
Silicone is forgiving but it does absorb odour over time if you neglect it. After each session, rinse the body with warm water. For a deeper clean every week or two, soak the silicone parts in a mix of warm water and isopropyl alcohol (90% or higher works best), then rinse thoroughly. The glass downstem and bowl can be soaked in isopropyl alcohol separately — a zip-lock bag with alcohol and coarse salt does the job in about 30 minutes. The stainless steel base just needs a wipe down. Avoid putting the glass components in the dishwasher; the silicone body is technically dishwasher-safe, but hand washing gives you more control.
Frequently Asked Questions
Is the Kube Silicone Oil Bong safe to use with concentrates?
Yes. The body is made from food-grade silicone rated for high temperatures, and the actual vapour path runs through a glass downstem and bowl. You're not heating the silicone directly — the torch only contacts the glass components.
Can I use the Kube as a regular bong for dry herb?
It's designed as an oil bong for concentrates, and the included bowl and downstem are optimised for that. You could technically use dry herb with the glass bowl, but the L-shaped downstem and chamber size are built with dabs in mind. For dry herb, a dedicated silicone bong with a larger bowl would serve you better.
How durable is the silicone body really?
Very. PieceMaker's medical-grade silicone flexes on impact — you can drop it on concrete and it bounces. The weak point is the glass downstem and bowl. Those need care. The silicone body itself is essentially unbreakable under normal use.
Does the Kube smell when stored?
If you clean it after each session and store it dry, odour is minimal. Silicone can absorb smells over time if residue builds up, so a weekly deep clean with isopropyl alcohol keeps it fresh. The sealed base helps contain any residual scent during transport.
What size is the Kube when packed up?
Roughly the size of a large Rubik's cube — compact enough to fit in a jacket pocket or small bag compartment. All 5 removable parts (mouthpiece, downstem, bowl, dab tool, Kontainer) store inside the body with the steel base screwed on.
Can I replace the glass downstem if it breaks?
PieceMaker uses a standard L-shaped glass downstem. If yours breaks, contact us — we can help you find a compatible replacement. It's the one part worth having a spare of if you travel frequently.
How much water should I put in the Kube?
Just enough to submerge the bottom of the downstem by 1-2cm. The cube shape means the water volume is smaller than a standard bong — overfilling leads to splashback through the mouthpiece. Less is more here.
