Blast-One Weekly Tips
Tip #07
Using Quick Connect Air Fittings

Workplace Health and Safety regulations require breathing air hose fittings to be of a design that prevents accidental disconnection. This means that fittings are to be either threaded or double action.

When using Breathing Air, it is critical that the best quality hose and connectors are used for maximum safety and peace of mind.

Blast-One breathing air hoses come with either threaded nut and tail fittings that comply with this requirement or double action hose fittings. These require two distinct actions in opposite directions to open them, thereby preventing accidental disconnection.

Accidental disconnection could result in the operator experiencing a loss of air supply and would require immediate action. The operator may need to remove themselves from the blasting area to reconnect the fresh air supply in a location that is free of contaminated air.

Conection instructions

These approved Breathing Air Quick Connect air fittings have the unique ‘Double Action’ which prevents accidental disconnection if the coupling gets ‘snagged’ or pulled.

Available as hose tails (male and female threads) with durable chrome plating which gives them an extra long life.

Conection instructions

To connect, simply push the two parts of the Double Action Quick Connect Couplings together - snap locked for your protection.

To release, push the two parts towards each other, move the sleeve in the opposite direction and pull the two parts apart - easy but very effective. When the two couplings are separated, the air to the connector is closed off by the internal valve in the air supply side of the two components.

Joiners

Standard Nitto or Rico type fittings are not suitable for use on breathing air lines because of the ability for them to be disconnected in a single action.

Under AS1715 and AS1716 you must use hose joiners that will not come apart if the joiner is caught or snagged. Double Action Quick Connect Couplings comply with this Standard
