Coilhose Pneumatics 15C90B4H Hose Coupling 1/4 in Brass

Product Description

The COILHOSE PNEUMATICS 15C90B4H is a brass pneumatic hose coupling designed for industrial compressed air and pneumatic fluid systems. It uses a hose barb thread type and features a 1/4 inch body diameter with a 1/4 inch hose inside diameter, making it a straightforward inline coupler for connecting air hose to pneumatic tooling or distribution lines. The coupler follows the Industrial Interchange standard, one of the most widely used coupling formats in shop and industrial environments. Installation is handled by HVAC technicians, maintenance mechanics, pipefitters, or experienced pneumatic system technicians.

This coupling is suited for general industrial and commercial pneumatic applications where a reliable, standard-format hose barb coupler is required. It connects 1/4 inch ID air hose to Industrial Interchange-compatible pneumatic fittings and quick-disconnect systems. Common install scenarios include compressed air tool hookups, pneumatic control lines, and equipment maintenance in shop, warehouse, and light industrial settings.

Key Features

• Industrial Interchange coupling format for broad tool and fitting compatibility
• Brass construction for corrosion resistance in compressed air service
• 1/4 inch body diameter with 1/4 inch hose inside diameter
• Hose barb thread type for secure, push-on hose attachment
• Compact, single-piece coupler design suited for inline connections

Compatibility

Designed as an OEM-style replacement or new-install coupler for pneumatic systems using Industrial Interchange standard fittings and 1/4 inch ID air hose.

Installation Notes

Installation is typically performed by a qualified pneumatic systems technician or maintenance mechanic. Always depressurize the air line and bleed residual pressure before disconnecting or installing any pneumatic fitting. Ensure the hose inside diameter matches the barb size before seating the hose. Inspect the barb connection for a secure, leak-free fit before returning the system to service.
