Product Description


Our vacuum bags have been getting great comments and it seems that each review mentions the flush-mount bag stem as a key improvement. This kit allows attachment to the vacuum bag with our lock-on connector without worry of project surface imperfections caused by the protrusion of our regular bag stem.

These improved bag stems have a specially designed 2.5" diameter 50 mil flange molded onto the valve body. A sharp-barbed brass insert slides into the molded flange body and locks into place. With the included cement, the bag stem is permanently attached to your vacuum bag. While other companies are selling something similar for $25 to $35, our unit is about half of their price and works twice as well. This stem assembly allows the lock-on vacuum connector (not included) to be attached with simple finger pressure.

Made in the USA!


Notes

  • If you are currently using our other bag stem type, you can remove it and easily cement on this improved version!
  • Be sure to order the bag stem flange material type that matches the vacuum bag you are building. Do not use a polyurethane flange on a vinyl vacuum bag.
  • If you have ordered a vacuum bag from us, it will include a bag stem. See the vacuum bag product page for additional information.
  • This bag stem is designed to attach to our lock-on vacuum connector.

Will the flange on this kit adhere to nylon and other surfaces?
I honestly do not know the answer to that question. If you try it, please let me know and I will post your comments here.

What is the thread size on the top of the brass fitting?
It is a standard Schrader thread which is .305" OD and 32 tpi.

Can I order just the flange or just the brass insert?
The flange can be found by clicking here. The insert can be found by clicking here.


Product Reviews

  1. I highly recommend this company.

    Review by Wm. H. Grady

    Its just a valve stem but its worth my review because it solved a major problem for my company. I have a bag from [another supplier] and it had leaks from many months of abuse. When my helpder decided to build a custom bent form for the bag we decided it was time to fix the leaks and move the valve stem to a more practical location. I contacted this company and Joe replied with a suggestion to use this valve core and then to upgrade to the bag connector that he sells. He also was able to provide me with cement and a patch kit for fixing my bag and closing up the hole from the old valve. My total investment to fix/update a $300 vacuum bag was only $35. I highly recommend this company.

    My shop foreman used this on a custom vinyl vacuum bag we needed for a large desktop. This stem is excellent. No leaks at all and took less than 5 minutes to apply. I recommend this stem - Two thumbs up.


  4. This is a great product with no fuss.

    Really didnt want to get involved in gluing a stem to my bag. I just dont have much time these days but. But the process took about 3 minutes and the bag was ready to be used a few hours later. It was no big deal at all. Joe emailed me to follow up and see if I had any questions. This was a welcome surprise and something you just dont find anymore when dealing with any company; especially an internet outfit. If you have a worry about this product or this company, you'll find that there is really not much worry about here. I'm very pleased with everything I've bought here.


  5. A great improvement on the original idea.

    I have several of the VS vacuum bags in my shop and I've been a customer of Joe's for several years. There are few companies in the world that offer service like this. I can tell by Joe's emails to me that he's always looking to make his products better, faster, or just more sensible. This is a great example of his methodology. The stem is simple and process of attaching it is as easy as can be. For the money, this type of connection is about as perfect as can be.


  6. Works For Me

    I updated my old vacuum bag from [another supplier] using this product and the locking connector. Works fine. No complaints. Arrived quickly.


  7. Much better than the heavy duty version

    Review by Bryce Anderson

    I have been buying vacuum pressing stuff from Joe for years and I've built several vacuum bags (vinyl) over the years. I currently have 6 of them that I custom made. Each bag has the older valve stem. Those stems are great and I really have no complaints about them but it must be understood that they do have a bit of an effect on the veneer because they can leave depressions on the veneer. The new valve stem eliminates this problem. I've updated each of my bags with the new stem and I'm glad I did. The brass part of this stem is machined flawlessly. The barbs on it are astonishingly sharp and as the instructions say, the barb will not come out of the nipple part. The process of adding the valve stem takes less than 10 minutes. By the time I did my 3rd stem, I was done in half that time.


  8. Just What I Wanted!

    Review by Victor Newman

    I bought several of these valve stems so I could convert some old vacuum bags to use the lock on connector offered on this website. That connector really simplifies the attachment process. The new valve stems are just wonderful. The application instructions are clear and well written and the product itself is nicely machined. My old bags are like new and now my connection is 100% perfect.
