Quick Connect Couplings


Safety, energy efficiency and dependability are at the centre of Air Energy’s quick connect couplings. Air Energy recommend only reliable brands and styles, there are other imitation or copies on the global market, but pressure drop caused by poor internal design can be a very costly but hidden running cost.

ACCIDENTS IN THE WORKPLACE can be costly. Injured employees suffer, and companies can experience financial setbacks. The power of compressed air has the potential to cause serious or even fatal injuries. One dangerous situation occurs when operators use their fingers or hands to block the air stream, such as when dead-ending a blowgun. The incoming air can damage human tissue severely, and even a small amount of injected air can adversely affect blood supply.

Also, when disconnecting a long length of hose under pressure, the blast resulting from the sudden expansion of air has the potential to startle operators, whiplash can cause physical injury as well as cause hearing damage.

  • A blast of air under 40 p.s.i. from 4 inches away can rupture an eardrum or cause brain damage.
  • As little as 12 p.s.i. can pop an eyeball from its socket.
  • Air can enter the navel, even through a layer of clothing, and inflate and rupture the intestines.
  • Directed at the mouth, compressed air can rupture the lungs

Since compressed air has the potential to cause serious operator injury, its handling is safeguarded by industry standards and usage guidelines. Employers are responsible for ensuring the safety of employees by providing instructions on the proper use of compressed air, as well as providing equipment and tools that are safe to use.Standards regarding the use of compressed air differ from country to country. We believe strongly in the importance of caution in using compressed air and below are some applicable standards around the world.

  • Australia’s “Duty of care” requires everything reasonably practicable to be done to protect the health and safety of others in the workplace.

As such, it is your responsibility to ensure that you have taken all relevant steps to ensure the safety of all personnel within your area of responsibility. Manufacturers in Australia can fulfil this responsibility by specifying pneumatic products that comply with such internationally known standards as:

  • European Standard EN 983:1996 – Safety of Machinery Paragraph
  • International Standard ISO 4414 – Pneumatic Fluid Power Paragraph 9.6

Both standards specify the same functional requirements for quick-action (release) couplings in pneumatic fluid power systems.

  • International Standard ISO 4414 – Pneumatic fluid power Paragraph 4.2This standard specifies hazards that need to be eliminated by system design, or by means of a system design that incorporates safeguards against such hazards.

Frequency of Use

HiCupla Ace HA function

The frequency of use has a bearing on coupling selection. For heavy-duty use, selection of materials that maximise wear resistance should be considered.


Safety, of course, is a major consideration and this will depend on your plant’s design and the air volume in the pipes or hose. Consider a coupling equipped with a ball check valve or a zero-pressure coupling to prevent hose whipping.
