This is a functional and affordable vacuum bag closure that has a couple of nice improvements over standard plastic bag closures. Our closures are made from PVC instead of ABS or polystyrene, which gives it greater clamping strength and durability. Unlike other plastic closure systems, the PVC will not stretch or weaken over time.
Made in the USA!
This new closure has an angled edge on the sleeve component, making it very easy to snap over the tube. It's a small change but a huge improvement. You'll find that our bag closure is nearly 100% larger than some competing bag closures. This additional surface area provides more clamping power and is much easier to use._

Additional Information
International Orders
The bag closure may ship separate from other items in your order. Because of this, there is an additional handling charge for non-US destinations.
Is there a way to connect two or more closures together for a very large bag opening?
Option 1: A small piece of .75" poplar dowel can be jammed into the end of the tube part of the closure. The dowel diameter needs to be reasonably accurate for this to work correctly. I've had success forcing half of a 3" dowel into one side of the tube and then lightly sanding the other side so that the second tube can be attached without forcing the dowel further into the first tube.
Option 2: A friend 3D printed some couplings for me not long ago. You can find them here.
With either of these options, there can be a small leak where the closure pieces butt together, though it shouldn't be so bad that the vacuum system can not overcome it.
What can I do to make it easier to remove the closure from the bag?
It is easier to attach the closure and remove it from the bag if a light coat of carnauba-based car wax is applied to the inside of the C-channel and the area of the bag where the closure is attached.
