Chicago-style universal air hose coupling enables fast, tool-free hose connection for portable air and water lines.
Its crowfoot claw structure supports frequent reconnections while maintaining stable airflow and tight seals in harsh working conditions.
A broad size range is ready to meet diverse on-site piping demands.
Universal claw air hose coupling is for air hose and water hose.Two lugs are designed for 1/4", 3/8", 1/2", 5/8", 3/4" and 1" air king universal coupling. On 1-1/4", 1 1/2" and 2", there are 4 lugs.
Beyond air and water hoses, these couplings are widely used in compressed air systems, pneumatic tools, construction equipment, and sandblasting applications.
One feature worth noting: all 2-lug couplings from 1/4" to 1" are fully interchangeable with each other, whether male, female, or hose ends. The same holds true for 4-lug couplings from 1-1/4" to 2". As a manufacturer of air hose fittings in China, we manufacture this interchangeability to simplify stock management – you don't need to match specific ends, just grab the right size.
To provide protection against coupling breakage and related hazards, you can use whipcheck safety cable to avoid any danger because of sudden disconnection.
The working pressure could be reached 150 PSI at ambient temperature.
These crowfoot fittings are designed for compressed air and water service only. They are not suitable for steam, oil, or chemical applications.
Air king iron air hose fitting can be called jackhammer coupling or claw coupling.

When choosing a chicago-style fitting, match the size to your hose inner diameter – too small restricts airflow, too large won't seal. For end types, hose ends are for attaching to hose; male and female ends are for connecting to other fittings. As a China-based supplier, we offer thread options: NPT is standard for North America, and BSP is available upon request for bulk or OEM orders.
