Infinity Quick Coupler: Universal Socket (Male NPT)

One Coupler to Connect Them All

Eliminate the frustration of mismatched air fittings with the Infinity Universal Quick Coupler (Male NPT). This versatile socket is engineered to solve the most common problem in busy workshops: figuring out which plug profile you need.

Designed with a specialized internal geometry, this “Universal” socket automatically accepts the three most common plug standards found in North America. Whether your tools are equipped with Industrial (M-Style), Automotive (T-Style), or ARO (210-Style) plugs, this single coupler locks them all in securely without leaks.

The “Problem Solver” for Mixed Environments

If you have tools from different manufacturers or older equipment mixed with new, you likely have a drawer full of different plugs. The Infinity Universal Coupler standardizes your connection points.

• Male NPT Connection: This model features a Male NPT thread, designed to screw directly into female-threaded ports. It is perfect for installing into wall manifolds, FRL outlets, or the end of an air hose.

Key Features & Benefits

• 3-in-1 Universal Compatibility: Accepts the following plug profiles indiscriminately:
  1. Industrial Interchange (MIL-C-4109 / ISO 6150 B) – The most common “standard” plug.
  2. Automotive / Tru-Flate – Common in garages and tire shops.
  3. ARO 210 – Common in industrial assembly tools.
• Heavy-Duty Locking Mechanism: Features a robust 6-ball locking system (superior to the standard 3-ball or pin designs). This provides more contact points on the plug, ensuring stable alignment and reducing the wear that causes leaks over time.
• Rugged Construction: Built from hardened steel and brass with a nickel-plated finish. This coupler withstands the rough handling of daily shop use and resists corrosion from moisture in the air lines.
• High-Flow Performance: Despite accepting multiple profiles, the internal valve design minimizes airflow restriction, ensuring your impact wrenches and sanders get the full power they need to operate.
