Air hoses are used in underwater diving, such as scuba diving, to carry air from the surface or from air tanks or diving pumps to the diver. Air hoses are therefore a necessary part of standard diving dress and any type of surface supplied diving equipment. They are an essential part of scuba diving equipment, used to deliver pressurised air from the first stage of a diving regulator to the other components. Air hoses are used between locomotives and railroad cars for their brakes, and are also used between those tractors and semi-trailers which use air brakes.

In this article, I’ll explain everything you need to know about air hoses when diving.

What is an air hose

High Visibility, Kink-Resistant Professional Diving Hose

What You Need to Know

If you’re a professional diver, you know that having the right gear is essential. That’s why you need a heavy-duty, kink-resistant, high-visibility diving hose. It’s often colored optic yellow so you can easily spot it in the water, and it even floats on the surface to reduce tangles.

Available Lengths

We’ve got you covered no matter what length you need:

  • 6 m / 20 ft. – AH20
  • 9 m / 30 ft. – AH30
  • 12 m / 40 ft. – AH40
  • 15 m / 50 ft. – AH50

Of course, there are much longer diving hoses for Snuba as well, where the air is taken from the surface to the diver.

Solving Air Problems with High Pressure Air Hoses

What are High Pressure Air Hoses?

High pressure air hoses are the connectors between air compressors and other devices. They’re used in a variety of applications, from scuba diving to connecting tractors and semi-trailers. They’re made up of three parts: a tube, reinforcement and a cover. The tube is usually made of a high-quality, black, smooth synthetic rubber that’s resistant to abrasion, corrosion and oil. The reinforcement is made of multiple layers of high-strength synthetic fibers, making the hose strong and durable. The cover is made of a high-quality, black, smooth chloroprene rubber that’s resistant to fire, abrasion, corrosion, oil, weather, ozone and aging.

Types of High Pressure Air Hoses

High pressure air hoses come in a variety of types, each with its own advantages:

  • Textured Surface Hose: This type of hose has a textured surface that makes it easier to grip and handle.
  • Smooth Surface Hose: This type of hose has a smooth surface that makes it easier to slide and maneuver.
  • High Pressure Air Hose with Black Cover: This type of hose is designed to handle high pressure and is covered with a black cover for extra protection.

The Benefits of High Pressure Air Hoses

High pressure air hoses have a number of benefits, including:

  • Long service life: The high-quality materials used in the construction of the hose make it resistant to abrasion, corrosion, oil, weather, ozone and aging, ensuring a long service life.
  • Working temperature range: The hose can be used in temperatures ranging from -15°C to +70°C.
  • Working pressure: The hose can handle a pressure of up to 1.75 MPa (260 psi).

Applications of High Pressure Air Hoses

High pressure air hoses are used in a variety of applications, including:

  • Tunnels, mines and road construction
  • High pressure industries, such as service stations, factories, airlines, pesticide spraying and automation machinery
  • Pneumatic lines

Conclusion

Air hoses are an essential part of diving equipment that connects your scuba tank to your diving regulator. They’re made from high-quality materials and are highly durable so they can withstand the pressure of diving.
