Coilhose Pneumatics 14-04BS Ball Swivel Plug Aro Brass

Product Description

The COILHOSE PNEUMATICS 14-04BS is a ball swivel plug pneumatic coupling designed for compressed air systems in industrial and trade service environments. Constructed from brass, it features a 0.25-inch body diameter and a 0.25-inch male NPT threaded connection. The ball swivel design allows the connected hose to rotate freely, reducing hose twist and kink during operation. Rated to 225 psi maximum working pressure, this coupling is suited for demanding shop air, pneumatic tool, and production line applications. Licensed HVAC technicians, plumbers, pipefitters, and general mechanical contractors install this type of fitting as part of compressed air distribution and hose assembly work.

The 14-04BS is intended for use in ARO interchange pneumatic systems, making it compatible with ARO-style couplers and plugs common in automotive, industrial, and mechanical service environments. The MNPT thread type allows direct connection to standard NPT-threaded ports on air tools, hose ends, and manifold assemblies. It is equally at home in light-duty shop setups and heavier production pneumatic systems where reliable, swivel-action connections are needed to maintain hose management and reduce wear on fittings over repeated connect and disconnect cycles.

Key Features

• Ball swivel plug design allows free 360-degree hose rotation, minimizing kink and twist
• ARO interchange type for broad compatibility with ARO-style pneumatic systems
• Brass construction for corrosion resistance and durability in compressed air service
• 0.25-inch body diameter with 0.25-inch MNPT threaded connection
• Rated to 225 psi maximum working pressure
• Threaded connection type for secure, leak-resistant assembly

Compatibility

Designed as an ARO interchange replacement or addition for pneumatic hose and tool systems using ARO-style ball swivel plug couplings with 0.25-inch MNPT connections.

Installation Notes

Installation is performed by qualified mechanics, pipefitters, or pneumatic system technicians. Depressurize and bleed down the air line completely before removing or installing any coupling. Apply thread sealant tape or compound to the MNPT threads per the fitting manufacturer's recommendation and applicable shop practice, and tighten to a snug, wrench-tight fit without over-torquing brass fittings. Verify there are no leaks under pressure before returning the system to service.
