First you need to identify which type of fuel cartridge you need. You can determine this by looking inside the cap you screwed off to expose the fill valve. The inside of the cap will be color coded red, gold, blue, or green. Use a Dupont refill cartridge of the corresponding color. You can refuel a Dupont lighter using a steady hand and a regular butane cannister, but I don't recommend it. I broke the valve on one of mine that way after successfully refueling it for over a year. I was traveling a lot, and had a hard time finding Dupont fuel cartridges, so I got in the practice of using whatever butane I could find. Don't do this. Even if you've got practice at it, you'll probably break your lighter eventually and they're expensive to fix. There are metal screw-in adapters available, which will work just fine, too. Again, these are coded as to the type of lighter indicated by the color under the fill cap.
So, once you have either a metal adapter or a Dupont cartridge that fits your lighter, remove the fill cap, lightly press down on the valve stem to release any remaining gas and air which may have leaked in, and then firmly screw in either the gas cartridge or the adapter. If you're using a gas cartridge, simply let it sit until the cartridge is visibly empty, and then quickly unscrew the cartridge. The cartridges are single use, and your lighter is now refueled. If you're using an adapter, use a butane can with a cone shaped plastic sleeve over the valve stem, and press firmly against the hole in the adapter. Fill until butane begins to leak around plastic sleeve, remove the butane can and quickly unscrew the adapter. Some people recommend freezing the lighter first, by placing it in the freezer for several minutes. The theory is that a cold lighter will allow a larger amount of fuel in before the pressure balances against the remainders in the cartridge. I haven't found this to actually give any benefit. If more fuel is successfully transferred to the lighter this way, it's a very small amount and doesn't make a significant difference.
When refueling, it's also a good time to check your flint. Running a flint too short can result in pushing the flint ram against the striker and cutting a groove in the flint ram. It'll still work after you've damaged the ram in that way, but it's a preventable bit of damage and really annoying should you accidentally do so.
Grab the wind screen around the wick and pull it up away from the bottom of the lighter. The whole thing should slide out, it is a tight fit. Resoak the cotton batting in the bottom with lighter fluid. Do NOT use gasoline, use lighter fluid!
Don't over fill. The lighter fluid will burn your skin if it sits on it for a while. Experienced users drop a couple of extra flints in the bottom so they have them if they are needed. You'll see a screw in the middle of the batting, that is for you to put new flints in.
Fill the lighter with traditional lighter fluid. It is made to be used in the lighter. Two common brands are Zippo and Ronsonal. These will evaporate less quickly in the lighter than alternatives which can be dangerous.
Butane.
Sorry No Refill!! This was a disposable lighter.
no you can not refill a bic they are factory sealed
no, it can't be used because it is a bit more flammable and is can cause the lighter to explode because of the pressure
No, you cannot refill a Scripto wind-resistant kitchen lighter. These lighters are designed for one-time use and are not refillable. Once the fuel runs out, the lighter should be disposed of properly and replaced with a new one. Attempting to refill a disposable lighter can be dangerous and may result in malfunction or injury.
You cant
Yes, with butane
To refill a butane lighter, first, ensure it's completely empty by purging any remaining fuel. Next, turn the lighter upside down and insert the butane fuel nozzle into the refill valve on the bottom of the lighter. Press the can of butane firmly into the valve for about 5-10 seconds. Allow the lighter to sit for a few minutes before using it to allow the fuel to stabilize.
The pressure inside a Ronson butane refill can used for cigarette lighters is typically around 30-40 psi. It is important to handle these cans with care and follow safety instructions to prevent accidents.
To refill a vintage Stratoflame lighter, you will need a can of high-quality butane fuel. Make sure to use filtered butane to prevent clogging the lighter's internal components. Refill the lighter in a well-ventilated area and follow the manufacturer's instructions for proper refilling technique.
Slide the lighter body out of the lighter case, by pulling on the wick cage. With the lighter body upside down squirt lighter fluid into the fiber packing in the lighter until saturated. Reassemble the lighter body into the lighter case. Let excess lighter fluid evaporate before using the lighter.
Most disposable lighters are not refillable but if they are you should see a nozle on the bottom. For a zippo style lighter slight the lighter out of the metal casing and lift the rectangular pad and pour lighter fluid into the cotton underneath the pad
