Product Description

VS Extreme™ is the ultimate vacuum bag. Each bag is made from an extra-thick (30 mil) polyurethane material that has been designed for using an advanced thermoplastic capable of withstanding pressures exceeding 3,750 PSI and stretching more than 6 times its width and length*. VS Extreme vacuum bags offer superior resilience and unmatched puncture resistance. Made in the USA.

Each bag is welded with a state-of-the-art custom RF welding machine operating at 7,000 watts and 50 lb/in of pressure. This exact combination of frequency and clamp strength yields the most durable and airtight seam available. Each bag then undergoes a series of inspections including a final check that I do prior to shipment.

*Elongation and breaking strength based on ASTMD 412 test method.

Updated Stem Fitting
Our vacuum bags now come with a new style brass stem that works with the new lock-on connector included with all vacuum press kits purchased after February 10, 2020. The new lock-on connector and the required barb fitting can be ordered here for vacuum press systems purchased before the update.


  • New Flush-Mount Valve StemNew Flush-Mount Bag Stem - The VS Extreme vacuum bag also includes our new flush-mount bag stem assembly that allows you to use the full length of the vacuum bag without worry of project surface damage. A specially designed 2.5" diameter 50 mil flange is molded onto the polyurethane stem body and is permanently welded onto each bag. This creates an 80 mil total thickness reinforcement area for maximum durability.
  • Lubricant Infusion - VS Extreme vacuum bags are infused with a non-transferring lubricant that works in several ways to make vacuum bagging easy and trouble-free. This lubricant prevents most woodworking adhesives from sticking to the bag. Glue that sets on the bag simply peels right off. Unlike traditional urethane material, infused polyurethane allows the user to easily slide the platens and project panel into the bag without "blocking" or binding. The slippery surface makes inserting project panels a breeze.
  • Superior Resilience - Months of extensive testing resulted in a custom formulation that is unsurpassed in durability. VS Extreme bagging material typically withstands 650% more use than standard 30 mil vinyl.

  • This bag is sealed on three sides. Some users prefer to have two opposing open ends so that a shop helper can assist with loading larger projects from the other end of the bag. To do this, purchase an additional bag closure and simply trim off the end seal.
  • The vacuum stem is mounted in the center (left to right) and approximately 15" inward from the bag opening.

How do I attach my vacuum tube to this bag?
Our lock-on connector is required to connect a vacuum tube to this vacuum bag. This connector is included with all of our vacuum press systems.

What else should I know about the bag?
The maximum project size that is listed for this bag is approximate. It will vary because of tolerances in the manufacturing process. The maximum project size will also vary depending on the total thickness of the platens and project. You can maximize the usable size of the bag by using breather mesh instead of a top platen.

Does the vacuum bag have to stay connected to the vacuum press after full vacuum is achieved?
Yes because a perfect seal on a vacuum bag is virtually impossible. Here are some things to consider.

  • Sometimes the bag closure doesn't seat perfectly across the opening.
  • Sometimes the bag stretches a bit after full vacuum is created and then needs a bit of additional vacuum. This happens most often when there is a large project in the bag. You'll hear the vacuum system cycle off (if you have any auto-cycling system) and then turn on again for a few seconds. After that, it may not cycle again for several minutes or even hours.
  • After many uses some bags develop pin holes which can be almost invisible. In those cases, it's best to let the vacuum press keep the bag vacuum under control.

If the vacuum system is disconnected from the bag, you won't know if there is a leak because there is no vacuum gauge on the bag itself. If the bag is connected to a vacuum press system, you can easily see the vacuum level by looking at the gauge on the vacuum press. The vacuum inside the system is the same amount of vacuum inside the bag. If your vacuum press cycles on and off too frequently during a project pressing, you'll know there is a leak and if you can fix it. However, if you can't fix the leak, at least the vacuum system will keep manage the vacuum in the bag until the panel is finished.

Does epoxy stick to this polyurethane material?
I have tested the polyurethane with several brands of epoxy purchased from the local hardware store. The epoxy did release from the test samples. However, I've have received differing opinions about this from our customers and my guess is that it depends on the type of epoxy, how much epoxy comes in contact with the material, and how often the vacuum bag is used in this capacity.

One of our customers recently wrote...
"We're using West epoxy, and have had zero problems with the material sticking to the bags. Just pops right off. We're using it neat, and also with microfiber thickeners, and I can say there's no need to worry about sticking with West epoxy and these polyurethane bags." - Kenny Delapp, Albuquerque Joinery

Do you offer samples of this polyurethane material?
Yes. Please click here for details.

Product Reviews

  1. Extemely Happy

    Review by Jim Gallo

    As always, I’m extremely happy with my purchase. Not only do I receive quality products and fast shipping (always packaged with extreme care), I know that if I ever have a problem with my purchase, they will do everything in their power to make it right.

    The really BIG plus is, you can [email] with questions about your project, and Joe will answer your questions without acting like it’s a bother. There are other veneer supply companies out there, but why would anyone not use a company that goes above and beyond.

  2. Perfect for Holster Making!

    Review by Rhett Mahaley

    I am a leather holster maker, so I must first say that the use of your VS Extreme vacuum bag and press kit may be somewhat unconventional. However, this bag and press kit work wonderfully in forming and boning the leather. It is a very thick bag, able to withstand the work being done through the bag to the leather. Best money I've spent on tools and equipment for my work. Thanks so much, Joe.

  3. Quality Product, Quality Service, Quality Company

    Review by Bob Dickey

    The bag was exactly as described. Should last a long time. In terms of quality and support, it is just like everything else I have gotten from Joe, back to and including the pump and components to build my DIY vacuum press.

  4. Just What I Needed

    Review by Rick Vreeke

    The VS Extreme Poly Bag is an outstanding product and sized to accommodate my usual projects. I even got it at the special discount price which made it an even better deal. No regrets here!
    I also bought Joe's Vacuum Breather Mesh separately but wish now I'd just bought them together. It works better than what I'd sourced locally.
