When people think about getting a good result from a Powermatic, they usually focus on the machine or the tobacco.
The cigarette tube gets overlooked.
But tube size, condition, storage, and placement all matter more than most people realize.
A crushed tube, a bent opening, or a tube that is not seated correctly can easily make it look like something is wrong with the machine when the machine is actually working fine.
The two sizes Powermatic owners ask us about most are King Size and 100mm.
This guide explains the difference, how tube loading changes depending on the Powermatic model, what to check when tubes tear or do not fill properly, and which size may make more sense for you.
What Size Cigarette Tubes Do Powermatic Machines Use?
Powermatic machines are commonly used with both King Size and 100mm cigarette tubes.
The important part is that not every model handles those tubes in exactly the same way.
King Size is the standard choice for many Powermatic owners.
100mm tubes are longer and are preferred by people who want a longer finished cigarette.
Whichever size you use, follow the operating instructions for your specific machine instead of assuming every Powermatic works the same way.
This matters most with the Powermatic V+, because its automatic tube-loading system is designed specifically around King Size tubes.
King Size vs 100mm Cigarette Tubes
The biggest difference is simple:
100mm tubes are longer.
That sounds obvious, but the size you choose can also affect how you load the machine depending on the Powermatic model you own.
King Size Tubes
King Size is the standard format for many cigarette injector users.
It is widely used across the Powermatic lineup and is especially important if you own a Powermatic V+.
Why?
Because the V+ automatic tube-loading system is designed for King Size tubes.
If automatic tube loading is one of the main reasons you bought or are considering the V+, King Size is the size that lets you use that feature.
100mm Tubes
100mm tubes are longer than King Size.
They are a good choice for people who simply prefer a longer finished cigarette.
On Powermatic models that support them, 100mm tubes can be used according to the manufacturer’s operating instructions.
On the Powermatic V+, though, there is one important difference:
100mm tubes are loaded manually.
They do not go through the automatic King Size tube-loading system.
The Powermatic V+ Is a Little Different
The V+ deserves its own explanation because its tube system is different from the rest of the lineup.
One of the biggest features of the V+ is its automatic tube-loading chamber.
The system helps line up King Size tubes and move them toward the injection nozzle, which means you do not have to place every tube by hand.
That is a major convenience feature.
But it only applies to King Size tubes.
If you want to use 100mm tubes with the V+, you can still use them, but you load them manually according to the manufacturer’s instructions.
The quick version:
- King Size: automatic tube loading is available
- 100mm: manual loading is required

Tube Quality Matters More Than You Think
Not every filling problem starts inside the machine.
Sometimes the tube itself is the issue.
Before you load one, take a quick look at it.
Watch for:
- Crushed ends
- Bent openings
- Torn paper
- Deformed filters
- Moisture
- Tubes that look out of shape
- Any obvious damage
A damaged tube may not sit properly on the injector nozzle.
That can lead to:
- Tearing
- Wrinkling
- Uneven filling
- Partial filling
- Poor tube placement
So if your cigarettes suddenly start coming out wrong, checking the tube should be one of the first things you do.
Do not immediately assume the machine needs repair.
For more on incomplete fills, see our Why Is My Powermatic Not Filling Cigarette Tubes Completely? Causes & Fixes.
Why Do Cigarette Tubes Tear?
A torn tube can happen for several reasons.
Common things to check include:
- A damaged or crushed tube
- Incorrect tube placement
- Poor tobacco preparation
- Large stems or hard pieces
- Too much resistance during injection
- Tobacco residue around accessible parts of the injection area
If one tube tears once in a while, that does not necessarily mean anything is wrong.
Try a fresh, undamaged tube and check the tobacco.
If it keeps happening over and over, stop and look at the setup before wasting more tubes.
Do not take the machine apart or start making internal repairs yourself.
If the problem continues after normal troubleshooting, follow the manufacturer’s instructions and warranty process.
For more information, see our Powermatic Warranty & Service Guide (2026): What’s Covered and How to Get Help.
Tube Placement Matters Too
A perfectly good tube can still give you a poor result if it is not seated correctly.
If the tube is crooked, loose, or only partly on the nozzle, you may see:
- Partial fills
- Torn paper
- Crushed tubes
- Uneven cigarettes
- Failed injections
Do not force a tube onto the machine.
If it does not slide on the way it normally should, take it off and check:
- The tube itself
- The accessible nozzle area
Sometimes a small amount of residue is enough to make tube placement feel different.
The Powermatic V+ also includes tube detection designed to confirm that a tube is properly positioned before injection begins.
Sometimes a “Tube Problem” Is Really a Tobacco Problem
This is where troubleshooting can get confusing.
The tube may look like the problem, but the tobacco may actually be what caused it.
If the tobacco is too wet, too dry, full of stems, or packed poorly, it can create more resistance during injection.
That can affect the way the tube fills.
For better results:
- Break up large clumps
- Remove noticeable stems
- Remove oversized hard pieces
- Avoid tobacco that is overly wet
- Avoid tobacco that is extremely dry
- Do not force tobacco into the hopper or chamber
- Follow the loading instructions for your machine
The goal is not to cram more tobacco into the machine.
The goal is to help the tobacco move through the machine consistently.

How Should You Store Cigarette Tubes?
Tube storage is easy to ignore.
But cigarette tubes are lightweight paper products, so they can get damaged pretty easily.
Keep them:
- In the original box or protective packaging
- Somewhere dry
- Away from humidity
- Away from liquids
- Somewhere they will not be crushed or bent
Before loading a tube, give it a quick glance.
That five-second check can save you a lot of frustration later.
Do Different Powermatic Models Load Tubes Differently?
Yes.
One of the biggest differences across the Powermatic lineup is how much of the process you do yourself and how much the machine does for you.
The I+, II+, III+, and IV+ each have their own loading and operating process.
The V+ adds another level of automation by automatically loading King Size tubes.
That does not mean one style is automatically better.
Some people prefer manually placing each tube because it is simple and familiar.
Others like the convenience of the V+ doing more of the repetitive work.

King Size or 100mm: Which One Should You Choose?
There really is no “best” size for everyone.
It comes down to what you prefer and which machine you use.
King Size May Be Better If:
- You prefer the standard King Size format
- You own a Powermatic V+
- You want to use the V+ automatic tube-loading feature
- You want the size the V+ automatic system is designed around
100mm May Be Better If:
- You prefer a longer cigarette
- Your Powermatic supports the size
- You are comfortable following the loading process for your machine
- You do not mind manually loading tubes on the V+
Neither one is better across the board.
The right choice is simply the one that matches your preference and your machine.
Is It the Tube or the Machine?
When something starts going wrong, try to rule out the easy stuff first.
Before assuming the machine has a problem, check these five things.
1. The Tube
Is it crushed, bent, torn, damp, or misshapen?
2. Tube Placement
Is it positioned correctly according to the instructions for your machine?
3. Tobacco Preparation
Are there stems, clumps, or tobacco that is too wet or too dry?
4. Machine Cleanliness
Is tobacco residue building up around accessible areas?
Our How to Clean Your Powermatic Machine: Step-by-Step Maintenance Guide can help with that.
5. Operating Procedure
Are you loading and running the machine the way the manufacturer recommends for your model?
Going through those five things can save a lot of unnecessary frustration.
If the problem continues after you have checked them, then it makes sense to move on to the manufacturer’s troubleshooting or warranty process.

Final Thoughts
Cigarette tubes seem like a small part of the process, but they can have a surprisingly big effect on the final result.
The size matters.
The condition matters.
The way the tube is stored matters.
And the way it sits on the machine matters.
King Size and 100mm tubes are both commonly used with Powermatic machines, but the loading process can vary depending on the model.
The biggest example is the Powermatic V+:
King Size tubes can use automatic tube loading.
100mm tubes are loaded manually.
If you are dealing with torn tubes, incomplete fills, or inconsistent results, check the tube and your tobacco preparation first before assuming there is something wrong with the machine.
