Industrial Grade Air Tool Fitting for Professional Use

The RTC 022-M air plug is the industrial standard for New Zealand workshops. Designed to the Aro 210 profile, this male-threaded plug is most commonly used at the air inlet of pneumatic tools or on the ends of lead-in hoses. Unlike budget alternatives, RTC plugs are manufactured from hardened steel to resist the wear and deformation caused by high-vibration tools like impact wrenches and air hammers.

Why Choose RTC Hardened Plugs?

• Reduced Leakage: Precision machining ensures a perfect seal with your Aro couplers, preventing "hissing" and compressor cycling.
• Impact Resistant: Hardened steel construction means the "shoulder" of the plug won't wear down, preventing the plug from "popping out" under pressure.
• Universal NZ Fitment: Compatible with all major Aro-style couplers used in automotive and industrial shops across the country.
• High Flow Capacity: Internal bore is optimized to deliver maximum CFM to your air tools.

Pro Tip: When fitting this plug to your air tool, we recommend using 1–3 wraps of PTFE (Thread) Tape on the 1/4" BSP thread to ensure a 100% airtight connection.
