You can deflate a basketball with a standard basketball inflation needle. You do not need to attach the needle to a pump.
Wet or lubricate the needle first. Insert it straight into the valve and let the air escape slowly. Remove it once the basketball reaches the air pressure you want.
How to Deflate a Basketball With a Needle
You only need a standard basketball inflation needle.
The same needle used to pump air into a basketball can also let air out. If this is your first time deflating a basketball, the main thing is to be careful with the valve.
1. Wet the needle
Put a little water or soapy water on the needle before inserting it.
Wilson recommends wetting the needle because inserting it dry can damage the valve and cause air leaks. Spalding also recommends lubricating the needle before use.
2. Insert the needle straight into the valve
Push the needle straight into the valve rather than at an angle.
Avoid twisting it or pushing it from side to side. This puts unnecessary pressure on both the valve and the needle and increases the chance of damage.
3. Let the air escape slowly
Once the needle enters the valve, air will start leaving the basketball.
You do not need the pump attached. The hollow needle opens the valve and gives the air a way out.
If you overinflate a basketball, insert the lubricated needle and release a little air at a time.
If the inflated ball only feels slightly too hard, let a small amount of air out and check it again.
If you need to remove more air to save space when packing, you can gently press the outside of the ball while the needle is inside.
4. Remove the needle straight
Pull the needle back out in line with the valve.
Avoid bending or levering it sideways as you remove it.
5. Check the air pressure
If you are preparing the basketball for play, check the recommended pressure printed on the ball.
An air pressure gauge is the easiest way to measure the pressure accurately. It is more reliable than judging the ball only by feel or bounce.
FIBA requires approved basketballs to show their recommended inflation pressure or pressure range.
How Much Air Pressure Should You Let Out?
There is no single air pressure that is correct for every basketball.
If you are trying to reach your desired air pressure for play, check the pressure printed on your ball and use an air pressure gauge if you have one.
Spalding commonly recommends about 8 PSI, but that does not mean every basketball should be inflated to exactly 8 PSI.
If the inflated ball feels too hard, release the air slowly and check it again. This is better than letting too much out at once.
You also do not need to measure how long the needle stays inside the valve. Air can escape at different rates depending on the ball and its current pressure.
How to Deflate a Basketball Without a Needle
The safest option is to wait until you can get a proper basketball inflation needle.
That may sound boring, but the valve is easy to damage.
I ran into this problem myself when I wanted to use a basketball and realised I did not have a pump needle. It is tempting to look around the house for something that might fit, but that can turn a small inconvenience into a damaged ball.
Basketball manufacturer guidance reviewed for this article recommends using a proper inflation needle. I found no major basketball manufacturer recommending a paperclip, sewing needle, bobby pin, pen tube, or similar household object.
Can you use a paperclip?
I would not recommend it.
A basketball needle is hollow, smooth, and made to fit the valve. A paperclip is not.
Spalding warns that inserting a dry needle can damage the valve and cause air leakage. Using a rigid piece of metal that was never made for the valve adds more risk.
What about a straw or pen tube?
Some websites suggest using thin straws, pen tubes, and similar objects.
These are improvised methods rather than manufacturer-approved ones. A soft plastic tube may be less risky than a sharp piece of metal, but there is still no good reason to use one if you can get a proper needle.
Should You Fully Deflate a Basketball for Storage?
Usually, no.
The strongest storage guidance supports keeping a basketball inflated or slightly deflated rather than completely flat.
Store it in a dry, ventilated room away from direct sunlight, sharp objects, and extreme heat or cold.
You may see claims online that 4 or 5 PSI is ideal for storage. The research did not find reliable manufacturer or governing-body support for one universal storage pressure.
If you want to remove some air for storage, leave enough inside the ball for it to keep its normal round shape.
Do You Need to Deflate a Basketball for a Flight?
Not necessarily.
For example, the TSA allows basketballs in both carry-on and checked baggage and does not say they must be deflated first.
You can remove some air if you want the basketball to take up less space in your luggage, but there is no reliable universal rule saying it must be reduced to a certain PSI before flying.
Airline baggage rules can differ, so check the rules for the airline you are using.
Do Rubber, Composite, and Leather Basketballs Deflate Differently?
The basic process is the same.
Rubber, composite, synthetic leather, and leather basketballs all use the same valve-and-needle principle. The research did not find a separate deflation method based on the outer material of the ball.
The material matters more for things such as playing surface and general care.
Check the instructions for your specific basketball rather than assuming every model should be treated exactly the same.
Common Mistakes to Avoid
Avoid these mistakes when deflating a basketball:
- Using a dry needle
- Inserting the needle at an angle
- Twisting or levering the needle sideways
- Using a paperclip or another sharp household object
- Taking out much more air than you need
- Ignoring the recommended air pressure printed on the ball
- Storing the basketball in extreme heat or cold
- Assuming every unusual valve system works like a standard basketball valve
Valve damage is one of the main risks. Wilson warns that improper needle use can damage the valve and cause air leakage.
What About Spalding NEVERFLAT Basketballs?
Spalding gives NEVERFLAT basketballs their own valve and inflation instructions.
Spalding says not to inflate a NEVERFLAT basketball during its first year. If the ball develops a pressure problem during that time, the company recommends contacting customer care.
For older NEVERFLAT balls, Spalding gives separate instructions involving the valve cap.
If your basketball has an unusual valve system, check the instructions for that model before inserting a needle.
Frequently Asked Questions
Can you deflate a basketball with just the needle?
Yes. You do not need the pump attached. The needle opens the valve and allows air to escape.
Should you wet the needle first?
Yes. Wilson recommends using water or soapy water before inserting the needle to help protect the valve.
Can you use a paperclip to deflate a basketball?
It is not recommended by the manufacturers reviewed for this article. A proper basketball needle is the safer option.
Should you completely deflate a basketball for storage?
Usually not. Available storage guidance recommends keeping a basketball inflated or slightly deflated.
Do you need to deflate a basketball before flying?
Not as a general rule. TSA guidance allows basketballs in carry-on and checked baggage without requiring them to be deflated. Check your airline’s rules as well.
How do you know if you let too much air out?
For play, check the recommended pressure printed on the ball.
Use an air pressure gauge if you want an accurate measurement. Guessing from feel or bounce alone is less precise.
Final Takeaway
Deflating a basketball is simple if you use the right tool.
Wet a proper basketball needle, insert it straight into the valve, and release only as much air as you need.
Avoid sharp household objects that can damage the valve. For storage or travel, you usually do not need to flatten the basketball completely, and there is no reliable universal PSI that applies to every ball.
