How Much Pressure Should I Put On The Pneumatic Fender?


For the safe use of a boat, we need to purchase a pneumatic fender to protect the boat. For easy transportation, the pneumatic fender is usually purchased without air. So when we receive the pneumatic fender, all we need to do is inflate them before we can install them on the boat and use them. But how do we restart these fenders? How much pressure should we put on it?

Why is it important to use the correct pneumatic fender air pressure?

Determining the correct pressure for a pneumatic fender is an important aspect of keeping your boat protected and stable. The proper pressure may vary depending on the size and type of fender and the weight and size of the boat. However, a general guideline is to inflate the fender until it is firm, but still have some leeway when squeezing.

Over-inflation will make the fender too stiff and reduce its effectiveness in absorbing impact, while under-inflation will reduce its ability to protect. Refer to the manufacturer’s guidelines for specific pressure recommendations and consider factors such as the size of the boat, the conditions in which you will be docked, and your personal preferences to find the right balance for your fender.

Regularly check and adjust pressures as needed to ensure the fender performs optimally and protects your boat while moored and docked. Remember that pneumatic fenders are best inflated often, not just when you first buy them. This will give it a new start in life and contribute to its longevity.

Preparation stage

When we receive the pneumatic fender, it doesn’t have much air in it. For a small pneumatic fender, we can inflate it with a simple hand or foot pump. Inflatable, having the right nozzle is of the utmost importance. In fact, it is necessary to have a system that enters the valve and seals properly.

You can consult the pneumatic fender suppliers to get their advice on purchasing a matching inflatable. It is also possible to choose a universal small adapter, which usually has multiple functions.

Step-by-step inflation of the fenders

First, we unscrew the valve cover. This has a check valve in it that prevents the pneumatic fender from deflating after it is full of air and before you unscrew the valve cover. Inflate the fender using the inflation equipment you have.

How can I tell if my fenders are inflated enough? If you have a special test air pressure then that would be best. If you don’t have a gauge then you can use your finger to press on it. When you use your finger to press down on a pneumatic fender that has been inflated, it still has some slack in it, which will be nice when the boat is leaned over.

But the looseness should not be so great that the fender will not be able to provide protection. When the pressure in the fender is up to par, the valve must be closed with a plug.

Then use the same method to inflate the other pneumatic fender. Finally, install the correct installation method to mount the pneumatic fender you purchased on top of your boat. Next, you can use your boat without worrying about damaging it in your daily life.


A properly inflated fender provides the necessary protection for your boat while docked and moored, preventing damage to your boat and dock. Regular maintenance and vigilance to monitor fender pressure will ensure that your boat is always safe and secure, allowing you to enjoy a carefree time on the water. So take the time to find the perfect pressure for your pneumatic fender and your boat will thank you for years of damage-free docking.
