RTC Aro Higher Flow Air Coupler - 1/4" BSP Female Thread
Maximize Airflow with the Aro 210 Professional Series
The RTC 022 "Higher Flow" coupler is designed for workshops that demand peak performance from their pneumatic tools. While fully interchangeable with the standard Aro 210 profile used across New Zealand, this coupler features an optimized internal valve geometry. This allows for significantly higher air volume (CFM) delivery, ensuring your impact wrenches and grinders don't lose torque due to air starvation.

Why Upgrade to RTC Higher Flow?
- Eliminate Bottlenecks: Standard couplers often restrict flow. The RTC Higher Flow design ensures your tools get the full volume of air provided by your compressor.
- One-Hand Operation: Features a precision-engineered "push-to-connect" sleeve, allowing for fast, effortless tool changes without pulling back the collar.
- Leak-Free Reliability: Industrial-grade internal NBR seals eliminate the "hiss" of wasted air, reducing compressor wear and electricity costs.
- Universal NZ Fitment: Compatible with all standard Aro 210 plugs, CEJN 300 series, and Rectus 22 series.
Installation Recommendation
When installing this female-threaded coupler to a manifold or tool, we recommend using a high-quality thread sealant or PTFE tape on the male 1/4" BSP fitting to ensure a 100% airtight seal.


Aro Compatible - 25% greater flow than an average Aro coupler.
