Introduction: How to Vacuum Seal a Mason Jar

By Youtube Channel
About: I love to tinker and make things from other things. I post videos on my Youtube channel that showcase some of the silly homemade inventions and gadgets that I mess with. I'm also the guy with the most viewed …

Lets get started!

In this quick life hack, I'll show you how to make a super cheap vacuum sealer that you can use to vacuum seal mason jars! A really great build if you're a prepper!

Here's what you'll need

  • A 'Mason' jar - I used an empty jam jar that a friend was about to put in the trash can.
  • A syringe - Any syringe will do. Bigger is better.
  • 8 inches of air line tubing (pet store)
  • 2 check valves (pet store)
  • and a 3 way air line connector (Pet store)

Step 1: Watch the Video!

The easiest way to follow along with this Instructable, is to watch the video above or on my channel by clicking this link - http://bit.ly/1ODLIwG

Step 2:

Lets start by cutting 4 pieces of air line tubing to about 2 inches in length

Step 3:

Take 1 of the pieces, and cut one end at an angle like this.

Step 4:

Attach the other 3 pieces to the 3 way air line connector, Just like this.

Step 5:

Grab a check valve and for markings that say IN and OUT.

Step 6:

Attach the Input side of one check valve to the center of the 3-way connector and the syringe to any other side.

You should have something that looks like the last picture.

Step 7:

Next, unscrew the lid of the jar and drill a 4 millimeter hole in the center. I say 4 millimeters because the outside diameter of the air line I used was 5 millimeters. Try and make a hole that's half the size of the air line for best results! - So if your air line is 6mm , make the hole 3-4mm for the tightest fit.

Push the angled piece of air line that you cut earlier,through the hole.

Step 8:

Attach the input side of the other check valve to the lid and screw it back onto the jar.

Attach the 3-way connector to the check valve on the lid

It should look like the last picture.

Step 9:

Now begin pumping the syringe until you can't pull back the plunger.

I suggest using a bigger syringe to speed up the process.

Step 10:

You can undo the vacuum by simply detaching the check valve on the lid.

You can use this idea to extend the shelf life of anything from food to ammunition primers and powders.

If you've made it this far, congratulations!
