How to keep your padel and tennis balls pressurised

You open a new can of balls. There's a psst - and from that second, the balls slowly start to lose pressure.

It's nothing you're doing wrong. It's just physics. A padel ball has around 11 psi of pressure inside. A tennis ball has 14 psi. That pressure is what gives you a good bounce and precise feedback. When it disappears, you feel it in your game.

An opened tube of padel balls is almost unusable after a week - even if you haven't played with them. Rubber is porous, and air quietly seeps out. Heat, impacts and compression during play speed up the process.

What happens to your game?

A ball with too little pressure bounces lower than it should. It flattens on contact with the court and loses that precise bounce. The result is a slower ball with an unpredictable bounce - and in padel you notice it even more, because the sport relies on the ball's lively kick off the glass.

Many players simply keep playing and gradually adapt. But it affects your rhythm, your precision and how much fun you have more than most people realise.

What can you do about it?

There are two ways to deal with pressure loss.

One is to keep buying new cans. It's easy, but expensive - most active players open 40-50 cans a year.

The other is to store your balls under pressure between matches. When the pressure outside the ball is higher than inside, air is pushed back into the rubber instead of seeping out. The ball gets its bounce back. That's exactly what Pressurebox is built for.

How Pressurebox works

The principle is simple. Rubber always tries to even out the difference in pressure between the inside and the outside of the ball. Normally, pressure leaks out - because the pressure inside is higher. Pressurebox turns that around.

You store your balls in an airtight container at a higher pressure than normal, and air is pushed back into the rubber. Balls can be repressurised again and again with a bounce close to new.

Pressurebox Pro does it all automatically. Put the balls in, press the button, and the built-in compressor holds the pressure for you. The next time you open it, you'll hear the same psst as from a new can.

How to use it in practice

It takes less than a minute. After playing, put the balls in and close the lid. Pressurebox Pro holds the pressure automatically overnight.

Before your next match, open it and you'll hear psshh. Balls ready.

Instead of throwing the can away after two or three matches, you use the same set again and again - while the balls still play the way they should.

Frequently asked questions

Does Pressurebox work for both padel and tennis balls?
Yes. Pressurebox Pro is available in a padel version and a tennis version.

When should I start using Pressurebox with my balls?
From the first time you play with them. Balls with some pressure left regain their bounce faster than completely flat balls - so the sooner you start, the better it works.

Can I repressurise balls that are already flat?
Yes, but it takes longer. Leave them in your Pressurebox overnight and they'll be ready the next day.
