The Air King Universal Air Hose Coupling is a heavy-duty, quick-connect air hose fitting used primarily in compressed air systems for industrial, construction, and pneumatic tool applications. Its universal claw-style design allows interchangeability between different hose ends, regardless of hose size or manufacturer, making it a widely used standard for connecting air lines, hoses, or tools in rugged environments. Commonly referred to as: Chicago fitting, claw coupling, or universal coupling.
- Design: Universal Claw-Style Connection has two identical lugs (or claws) on each coupling allow quick, quarter-turn connections to any other Air King coupling of the same size. This coupling provides a positive, secure fit even under high vibration or movement.
- Applications:Air King couplings are used in high-volume air systems where quick and secure hose connections are necessary. Their rugged design makes them ideal for outdoor, industrial, and mobile applications.
- Construction Sites:Connecting pneumatic tools like jackhammers, impact wrenches, and chipping hammers.
- Industrial Facilities:Air distribution lines for compressors and machine tools.
- Mining and Tunneling:Durable air connections in underground or abrasive conditions.
- Shipyards and Steel Mills:High-durability air connections for maintenance and repair work.
- Temporary Air Systems:Rapid assembly/disassembly of hoses for mobile compressor units.
- Materials:Air King couplings are made from tough, corrosion-resistant malleable iron which is the most common and economical option. They are Zinc-plated or galvanized for corrosion protection and suitable for general industrial use.
- Configurations:
- Fitting Type: Blank End, Female NPT, Hose End, Male NPT, Triple Connect
- Size: 1/4″ to 1″
- Swivel or Non-Swivel
