Coilhose Pneumatics 15-04BS Ball Swivel Plug 1/4 Inch Mnpt

Product Description

The COILHOSE PNEUMATICS 15-04BS is a brass ball swivel plug coupling designed for industrial compressed air and pneumatic systems. It features a 1/4 inch male NPT threaded connection and a 1/4 inch body diameter. The ball swivel design allows the connected hose to rotate freely, reducing kinking and hose fatigue during use. Rated to 225 psi maximum working pressure, this coupling is built for demanding shop and field environments. Licensed HVAC techs, plumbers, and mechanical contractors rely on couplings like this for tool drops, blow guns, and pneumatic equipment hookups.

The 15-04BS follows the Industrial Interchange standard, making it compatible with the most common coupler bodies and plugs found in maintenance, repair, and operations environments. The MNPT thread type allows direct installation into male-threaded ports on hose assemblies, manifolds, or pneumatic tool inlets. Brass construction resists corrosion in air-line service and holds up well in environments where light moisture or condensate is present. This coupling ships as a single unit and is suitable for both permanent installations and portable air supply setups.

Key Features

• Ball swivel plug design allows 360-degree hose rotation, reducing kinking and wear
• 225 psi maximum working pressure for demanding pneumatic applications
• 1/4 inch MNPT thread for direct connection to standard NPT fittings
• Industrial Interchange type for broad compatibility with common coupler bodies
• Brass construction for corrosion resistance in air-line service
• Compact 1/4 inch body diameter suits tight installation spaces

Compatibility

Designed as an OEM-style replacement or direct addition for Industrial Interchange pneumatic systems using 1/4 inch MNPT threaded connections.

Installation Notes

Installation is performed by a qualified mechanic or pipefitter working on compressed air distribution systems. Always depressurize and bleed the air line completely before removing or installing any coupling. Use thread sealant tape or compound rated for compressed air service on NPT threads, and tighten to hand-snug plus the appropriate number of turns per standard pipe fitting practice without over-torquing brass fittings. Verify system pressure does not exceed the 225 psi rating of this coupling after returning the line to service.
