Coilhose Pneumatics B0504BS Ball Swivel Plug 1/4 Mnpt

Product Description

The COILHOSE PNEUMATICS B0504BS is a brass ball swivel plug coupling designed for pneumatic hose and air tool connections. Featuring a 1/4-inch male NPT threaded connection, this fitting allows 360-degree rotation at the hose connection point, reducing hose twist and kinking during operation. It is rated for a maximum working pressure of 225 psi, making it suitable for standard shop air systems. The all-brass construction provides corrosion resistance and durability in industrial and workshop environments. This type of fitting is typically installed by maintenance technicians, pipefitters, or experienced contractors working on compressed air distribution systems.

The B0504BS ball swivel plug is used in compressed air systems where hose flexibility and freedom of movement are required. Common applications include pneumatic tool hookups, air compressor hose connections, and shop air drops in both light commercial and industrial settings. The swivel action is particularly useful in high-traffic work areas where hoses are frequently repositioned or dragged across surfaces, reducing wear on both the hose and the coupling seat.

Installation Notes

Installation is performed by a qualified technician or pipefitter. Depressurize and lock out the compressed air supply before threading or unthreading any fittings. Apply thread sealant tape or compound to the MNPT threads per shop practice and applicable plumbing codes before installation. Do not exceed the rated 225 psi working pressure for this fitting.
