How to Replace the Flint
Remove the Insert
Open the lighter and pull the inside metal unit from the decorative case. Place the case on a soft cloth to prevent scratches.
Locate the Flint Spring
Turn the insert upside down. The flint spring is the long screw positioned beside the felt fuel pad.
Unscrew the Spring Slowly
Use a coin or screwdriver to loosen the screw. Remove it carefully because the attached spring is under light pressure.
Remove the Old Flint
Turn the insert upright and gently tap it so the worn flint falls from the tube beneath the spark wheel.
Insert the New Flint
Turn the insert upside down again and drop one new flint into the empty tube. Only one flint is needed.
Reinstall the Spring
Return the spring to the tube and thread the screw gently until it is fully seated. Keep it straight to avoid damaging the threads.
Test the Spark
Return the insert to the case and turn the wheel. If it initially feels tight, rotate it backward several times before trying again.
Signs the Flint Needs Replacing
| Symptom | Likely Cause | Recommended Action |
|---|---|---|
| No visible spark | Flint is worn out or missing | Install a new flint |
| Wheel spins freely | No pressure beneath the wheel | Check the flint and spring |
| Weak, occasional sparks | Flint is nearly exhausted | Replace it before complete failure |
| Wheel binds after replacement | New flint has not seated | Turn the wheel backward several times |
Do not mistake the brass-colored spring tip for an old flint. The tip remains attached to the spring and pushes the actual flint against the spark wheel.
Common Replacement Mistakes
Avoid placing several flints in the tube, cross-threading the spring screw or forcing a wheel that will not move. Also keep the insert away from open flames while performing maintenance.
Collector tip: Always remove the insert before working on it. This protects polished, painted, engraved and limited-edition cases from tools and accidental handling marks.
Keep Your Zippo Sparking Reliably
A fresh flint restores dependable ignition while preserving the familiar mechanical experience that makes a genuine Zippo enjoyable to own.

How do I know when the flint is worn out?
Common signs include weak sparks, no spark or a wheel that spins without resistance.
Where does the new flint go?
It drops into the narrow tube directly beneath the spark wheel before the spring is reinstalled.
How many flints should I install?
Install one flint at a time. Extra flints should be stored separately.
Why is the wheel stuck after replacement?
The new flint may need to seat against the wheel. Rotate the wheel backward several times and test it again.
Is the brass spring tip the old flint?
No. The brass-colored tip is permanently attached to the spring and should not be removed.
Can I replace the flint while fuel is inside?
Yes, but work away from flames and sparks, and wipe away any fuel found on the exterior before testing the lighter.
