The APEX Quad Air system is not just an ordinary “4-Tire Kit”... this is a professional system designed for people who want to inflate their tires faster, more accurately, and in a neat way without extra hoses or lines getting tangled under the car.

The basic idea is simple yet powerful: all four tires are connected, and the system automatically equalizes the pressure between them, whether you're inflating or deflating. The result? A balanced ride, faster inflation, and complete control from a single point.

🚀 Why is Quad Air different from any other system?

1) Air Up Faster – Faster inflation thanks to 3/8 High-Flow

The hoses used are 3/8" Nylon Braided, which provides a much higher flow rate than traditional 1/4" systems. The result: shorter filling time + better performance with powerful blowers.

2) Equalize Pressure – Automatic Pressure Balance

Once all four wheels are engaged, the system balances the pressure between them without any intervention from you. There's nothing more to it:

• Upper cover
• Less disbelief
• Fill each tire separately

They are all automatically equal.

3) Fit Your Rig Perfectly – Cut the hoses to fit your vehicle

The system comes with 42 feet of hose (12 meters ), which you cut yourself to fit your car. In other words:

• There's no extra hose running under the car.
• There are no short lines that don't reach
• Everything is tailored exactly to your car.

This is the main difference between APEX and ready-made “One-Size-Fits-All” systems.

4) Zero-Tangle Performance – It doesn't get tangled or complicated

The 3/8" Nylon Braided Hose is designed to be:

• What twists
• What is complicated
• folds flat
• It stores easily inside the bag.

⚙️ How it works

• Connect the hoses to the four wheels using Push-On Chucks .
• Attach the bellows to the input point.
• The system distributes air evenly to all tires.
• You can fill, deflate, or maintain pressure from a single point.
• Everything happens without you having to move between the wheels.
•
