Coilhose Pneumatics 15C90B6H Pneumatic Hose Coupler

Product Description

The COILHOSE PNEUMATICS 15C90B6H is a brass pneumatic hose coupler designed for use in industrial compressed air systems. It features a 1/4 inch body diameter and a hose barb thread type, accepting 3/8 inch inside diameter hose. Rated for a maximum working pressure of 300 psi and a temperature range of -40 degrees F to 250 degrees F, this coupler is built for reliable service in demanding shop and field environments. It follows the Industrial Interchange standard, making it broadly compatible with common pneumatic tool and hose setups. Typical installers include HVAC technicians, plumbers, and industrial maintenance professionals working with pneumatic equipment.

This coupler is suited for connecting pneumatic hoses to tools, compressors, and distribution lines in both shop and field settings. The hose barb connection style allows direct attachment to 3/8 inch ID rubber or reinforced air hose without additional fittings. The Industrial Interchange profile is one of the most widely used coupler standards in North American trade environments, making this part a common replacement or spare for general-purpose pneumatic systems. It is appropriate for residential, commercial, and light industrial compressed air applications.

Key Features

• Industrial Interchange coupler standard for broad compatibility with common pneumatic tooling
• Brass construction provides corrosion resistance and durability in compressed air service
• 300 psi maximum working pressure suitable for most shop air systems
• Wide temperature range from -40 degrees F to 250 degrees F
• Hose barb connection accepts 3/8 inch inside diameter hose directly
• 1/4 inch body diameter matches standard coupler sizing for pneumatic lines

Compatibility

Designed as an OEM-style replacement or direct-fit coupler for pneumatic hose assemblies using the Industrial Interchange standard with 3/8 inch ID hose and 1/4 inch body diameter connections.

Installation Notes

Installation is typically performed by a qualified technician or maintenance professional. Always depressurize the air line completely before disconnecting or installing any pneumatic fitting. Ensure the hose barb is fully seated and the hose is secured with an appropriate clamp to prevent blowoff under pressure. Verify that the connected hose and downstream components are rated for at least 300 psi before pressurizing the system.
