RTC Aro Higher Flow Air Coupler - 1/4" BSP Male
Professional Grade High-Volume Air Supply
Maximize your workshop efficiency with the RTC 022 "Higher Flow" series. While fully interchangeable with the standard Aro 210 profile found across New Zealand, this coupler is engineered with an oversized internal valve. This allows a significantly higher volume of air (CFM) to pass from your source to your tools, eliminating the performance "choke point" common in budget fittings.

Why Upgrade to RTC Higher Flow?
- Reduced Tool Bog-Down: By increasing flow at the source, your high-torque tools (impact wrenches, grinders) maintain consistent power under heavy load.
- One-Hand Operation: Precision-machined "push-to-connect" sleeve allows for fast, one-handed tool or hose changes.
- Leak-Free Seal: Industrial-grade internal NBR seals stop wasted air and prevent your compressor from cycling unnecessarily.
- Rugged Build: Heat-treated steel construction ensures this coupler survives the harsh environment of a busy workshop.
Pro Tip: When installing this male-threaded coupler into a manifold, use a liquid thread sealant or high-density PTFE tape to ensure a 100% airtight connection.


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