Coilhose Pneumatics 16-04BS Ball Swivel Plug 1/4 Inch Npt

Product Description

The COILHOSE PNEUMATICS 16-04BS is a brass ball swivel plug coupling designed for compressed air and pneumatic tool connections. The ball swivel design allows the connected hose to rotate freely, reducing kink and twist during use. Built to Tru-Flate Automotive interchange specifications, it threads onto standard 1/4 inch MNPT fittings and handles a maximum working pressure of 225 psi. The 1/4 inch body diameter and all-brass construction make it a durable choice for shop environments. Pneumatic technicians, mechanics, and service professionals install this coupling as part of quick-connect hose assemblies on compressors, air tools, and distribution lines.

This coupling is suited for both automotive service bays and general industrial pneumatic systems where Tru-Flate Automotive interchange couplings are the standard. The swivel plug configuration is commonly installed at the hose end, allowing the air hose to spin without binding at the connection point. It is appropriate for light to medium-duty compressed air service at pressures up to 225 psi. The all-brass body resists corrosion and holds up to shop contaminants better than zinc or plastic alternatives, making it a practical choice for high-cycle environments.

Key Features

• Ball swivel design allows 360-degree hose rotation to prevent kinking and twisting
• Tru-Flate Automotive interchange specification for broad shop compatibility
• 1/4 inch MNPT threaded connection for standard pneumatic fittings
• Maximum working pressure rated at 225 psi
• All-brass construction for corrosion resistance and durability
• 1/4 inch body diameter fits standard air hose assemblies

Compatibility

Designed for use with Tru-Flate Automotive interchange pneumatic systems. Fits standard 1/4 inch MNPT threaded ports on air hoses, compressors, and pneumatic tool connections.

Installation Notes

Installation is performed by qualified pneumatic or mechanical technicians. Depressurize the air line and disconnect the compressor before servicing any coupling. Apply thread sealant tape to the MNPT threads before installation and hand-tighten before applying wrench torque to avoid cross-threading. Verify the system is leak-free before returning to service pressure.
