At ATS Pneumatics Ltd, we are proud to be Christchurch’s largest stockist of pneumatic fittings, supplying a complete range of ARO style compatible couplers and inserts trusted in workshops and industries across New Zealand.
Our quick couplers are engineered for heavy-duty industrial applications, combining durability with ease of use.
Why Choose Quick Connect Fittings?
Rapid changeovers – connect or disconnect air tools in seconds.
Leak-free performance – precision-engineered seals reduce air loss.
Durable materials – nickel-plated brass and stainless steel resist corrosion in harsh environments
Universal compatibility – all of our couplers are ARO-style compatible, including profiles such as European, Italian, Swiss, and Japanese.
Safety options – We also supply safety couplings designed to vent pressure before disconnection, protecting operators.
Common Applications
Quick connect fittings are essential across industries such as:
Automotive workshops – fast tool changeovers for impact wrenches, grinders, and sprayers.
Transport & bus maintenance – ensuring safe and efficient pneumatic servicing.
Industrial manufacturing – supplying air to cylinders, valves, and machinery.
Construction – powering nailers, drills, and compressed-air site equipment.
General compressed air systems – making line management faster and safer.

How to Select the Right Quick Couplers
Choosing the correct quick connect fitting ensures safety, efficiency, and compatibility:
-
-
Identify the profile – European, Japanese, Italian, Swiss, or ISO. All of our ranges are are ARO compatible, but sockets and plugs must still match.
-
Check the flow requirements – larger DN sizes provide higher airflow.
-
Match socket and plug sizes – both must be from the same series/profile.
-
Consider safety couplers – where venting before disconnection is critical.
-
Ask ATS – our team can confirm the right product for your application.
