Liquid hoses
AIRBRAKE
AIRBRAKE is an EPDM compressed air brake hose specifically qualified per DIN 74310:1993 - the German standard for compressed air brake systems on vehicles and trailers. PN 10 bar working pressure and 25 bar burst pressure cover typical brake system pressures (6-9 bar operating with marginal peaks). The operating range -40 to +70 C makes the hose suitable for many climates, and the EPDM construction's weather and ozone resistance ensures long-term operation in exposed vehicle installations. Typically used on trucks, trailers, municipal sweepers, tractors and marine compressed air systems.

Why this hose?
The DIN 74310:1993 qualification is the central element in AIRBRAKE's value proposition. The standard specifies not only material stability and pressure rating, but also cyclic service life requirements, ozone exposure and low-temperature flexibility. EPDM-based brake hoses are the industry-recognised choice because the material meets all these requirements simultaneously.
Pressure margin 25/10 = 2.5x is industry standard for pneumatic brake systems. It covers working pressure cycles (typically 6-9 bar), pressure peaks at brake activation and pulsation effects from compressor operation. The safety margin is critical because brake failure has significant safety consequences.
The EPDM wall is specifically formulated to resist the external impacts typical on vehicles: ozone, UV, salt, temperature cycles and mechanical wear. Unlike NR (natural rubber) which becomes brittle under UV exposure, EPDM retains its elastic properties throughout the vehicle lifetime. This is the primary reason EPDM is the industry standard for brake hoses.
Where it is used
Automotive and truck manufacturing is the primary application. Compressed air brake installations on trucks above 7.5 tonnes, buses and trailers require DIN 74310-qualified hoses - AIRBRAKE is typically the right choice on OEM brake system installations.
Municipal services (sweepers, snow ploughs, municipal service vehicles) use the hose both as primary brake hoses and as compressed air distribution to other pneumatic systems. Weather resistance is critical here because vehicle brakes are often exposed to salt water, rainwater and thermal cycles.
Marine and agricultural applications use the hose for compressed air systems where DIN 74310 qualification is required or advisable. Marine installations are specifically exposed to salt exposure, and EPDM's resistance here is a major service life advantage.
The hose is colloquially known as a brake hose, compressed air brake hose or DIN 74310 hose.

Industries that use it
AIRBRAKE is used where compressed air brake systems on vehicles must be qualified per DIN 74310:1993 - typically in automotive, truck, municipal and marine vehicle installations.
Automotive and truck manufacturing is the main market. Compressed air brakes are standard on trucks above 7.5 tonnes and trailers - DIN 74310 is the defining standard for hoses in these systems. The EPDM construction's heat and weather resistance ensures the hose lasts through the vehicle lifecycle without frequent replacement.
Municipal services use the hose in sweepers, snow ploughs and service vehicles where compressed air drives brakes, door actuators and mechanical systems. The EPDM wall resists salt spray on winter roads and ozone exposure typical in urban environments.
Agriculture and marine applications are secondary markets. Tractor trailers use compressed air brakes similar to trucks, and marine compressed air systems on ships supply both brake and control air to mechanical systems. The hose's low-temperature resistance (-40 C) is particularly valuable in Nordic countries and marine installations.
Custom lengths and assemblies
The hose can be delivered cut to desired lengths. The standard roll can be supplemented with shorter pieces or multiple rolls by arrangement.

Frequently asked questions
What makes AIRBRAKE specifically a brake hose?
The hose is qualified per DIN 74310:1993 - the German standard for compressed air brake hoses on vehicles. The standard specifies material stability, pressure and temperature resistance and service life requirements for brake systems. The EPDM construction is the industry-standard material for this application due to its weather, ozone and heat resistance.
What is the operating temperature?
-40 to +70 C. This covers normal operating temperatures for compressed air brake systems on vehicles in many climates. EPDM retains flexibility at low temperatures where other rubber types would become brittle, and tolerates the moderate temperatures from brake friction and engine proximity.
How many dimensions are in the range?
2 dimensions: ID 11 mm and 13 mm. These are the typical dimensions for compressed air brake systems on vehicles. Both have the same pressure rating (10 bar PN, 25 bar burst) and 40 m standard roll length. The variation is in wall thickness: 11 mm has 3.5 mm wall; 13 mm has 6 mm wall.
What is PN 10 bar relative to actual operation?
Compressed air brake systems on trucks and trailers typically run at 6-9 bar working pressure. PN 10 bar provides margin to working pressure peaks, and 25 bar burst pressure is the actual failure limit. The safety factor 25/10 = 2.5x is typical for industrial rubber hoses.
Is the hose ATEX-approved?
The hose has NO explicit ATEX declaration on the factsheet. EPDM without specific antistatic additive is typically insulating. For ATEX zones with combustible gas or dust we recommend a conductive or antistatic variant.
Can the hose be delivered with pre-fitted brake couplings?
Yes - typical compressed air brake couplings are metric or US-specific (M14x1.5, 7/16-20 UNF) in metal crimp clamps or hydraulic couplings. We typically fit couplings to the hose by arrangement - send us your installation configuration and we'll advise on coupling choice and documentation per DIN 74310.
How long does a brake hose last?
The EPDM construction has long service life - typically 5-10 years in normal operation, depending on weather exposure and operating frequency. Brake hoses are typically replaced in connection with planned maintenance on vehicles (every 2-5 years) or if visual inspection shows signs of crack formation, ozone damage or mechanical wear.
Is the hose suitable for other applications than brakes?
Yes - the factsheet also notes general compressed air applications, suction trucks, silo trucks, compressors and compressed air supply. The EPDM wall's weather resistance also makes it suitable for outdoor compressed air installations at construction sites and municipal services. PN 10 bar is plenty for most construction site compressed air systems.
