Coilhose Pneumatics B0404BS Ball Swivel Plug 1/4 Mnpt

Product Description

The COILHOSE PNEUMATICS B0404BS is a brass ball swivel plug coupling designed for pneumatic hose and air line assemblies. It features a 1/4 inch male NPT threaded connection and a ball swivel design that allows the hose to rotate freely, reducing kinking and torsional stress during operation. Rated to 225 psi maximum working pressure, this fitting is suited for shop air systems, pneumatic tool hookups, and compressed air distribution lines. Installation is performed by licensed or qualified pneumatic technicians and experienced maintenance personnel.

The B0404BS is used in residential workshops, commercial garages, manufacturing facilities, and industrial maintenance environments wherever compressed air is distributed through threaded fittings. The ball swivel plug configuration is commonly installed at hose ends or quick-disconnect inlet points to allow hose rotation and reduce wear at the connection point. Its solid brass construction makes it appropriate for use in standard dry compressed air systems.

Key Features

• Ball swivel plug design allows 360-degree hose rotation to reduce kinking and line stress
• 1/4 inch MNPT threaded connection for standard NPT-compatible ports and fittings
• Rated to 225 psi maximum working pressure for typical shop and industrial air systems
• Solid brass construction for durability and corrosion resistance in compressed air service
• Compact, single-piece coupling ships individually for precise inventory control

Compatibility

Designed as an OEM-style replacement or add-on fitting for pneumatic hose assemblies using standard 1/4 inch NPT threaded connections in compressed air systems.

Installation Notes

Shut off and bleed down compressed air supply before removing or installing any pneumatic fittings. Apply thread sealant tape appropriate for compressed air service to the male NPT threads before installation. Hand-tighten first, then use a wrench to achieve a leak-free seal without over-tightening brass fittings. Verify all connections are leak-free under pressure before returning the system to service.
