In this life hack video, I am going to show you how you can refill your air duster can with a bicycle pump.
Step 1: Items Needed
All you need is an empty air can, some liquid metal epoxy and a tank valve similar to what is used on a bicycle tire. You will also need a drill and 3/8" bit.
Step 2: Make Sure Can Is 100% Empty
Start off by making sure there is no air left in the can. We really don’t want to start drilling the can while its pressurized.
Step 3: Use 3/8
Next, choose a drill bit that matches the width of the air valve. Mine happened to need a 3/8” drill bit.
Step 4: Thread Valve Into Hole
I decided to install the valve further down the can to keep it out of the way. Once the hole is made, you should be able to thread the valve right into the hole.
Step 5: Mix Liquid Metal Epoxy
Now its time to seal it up with the liquid metal epoxy. I cut the end from a cue tip to mix the 2-part solution together.
The cue tip also made it real easy to apply the epoxy directly to he valve. The instructions say it cures in 8 minuets I let it cure for a few hours. This stuff is rated for 3500 PSI so its complete overkill but its better to be safe than sorry.
Step 6: Connect Air Pump
Go ahead and attach a bicycle pump to the valve and let’s add some air!
The recommended pressure rating on this can was 70-90 PSI so lets keep this extra safe and only fill it up to 60.
