Dixon Valve Coupling 1040204C Barbed Hose Fitting

Product Description

The DIXON VALVE COUPLING 1040204C is a brass barbed hose fitting designed to connect 1/8-inch inside diameter flexible hose to a 1/4-inch female NPT threaded port. The barbed end provides a secure, leak-resistant grip on the hose, while the female NPT thread seals against a male-threaded fitting or port. At 1.15 inches overall length and a hex head size of 0.625 inches, this compact fitting suits tight installations where a standard wrench is needed to achieve a proper seal. Licensed plumbers, HVAC technicians, and industrial fluid-system installers work with this type of fitting in low-pressure fluid and air transfer lines.

This fitting is suited for residential and light commercial applications where 1/8-inch ID flexible hose must terminate at a threaded female NPT connection point. Typical install scenarios include equipment drain lines, compressed air lines, water supply connections, and similar fluid-handling assemblies. The NPTF thread standard ensures pressure-tight joints without relying solely on thread sealant, making it appropriate for demanding service conditions where leak-free performance is critical.

Key Features

• Brass construction provides corrosion resistance and durability in fluid and air service
• NPTF thread standard for pressure-tight, drip-free connections
• 1/4-inch female NPT thread mates to standard male-threaded ports and equipment
• 0.125-inch barb size secures 1/8-inch ID hose without clamps in light-duty service
• 0.625-inch hex head allows installation with standard open-end or combination wrenches
• Compact 1.15-inch overall length suits space-constrained plumbing and equipment enclosures

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 1/8-inch ID flexible hose terminating at a 1/4-inch female NPT threaded port.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified fluid-systems technician. Shut off and depressurize the line before removing any existing fittings or making new connections. Apply thread sealant tape or compound appropriate for the service fluid to the male threads before engaging the female NPT end, even with NPTF threads, for added assurance. Hand-tighten first, then use a wrench on the hex head to achieve a snug, leak-free fit without overtightening brass threads.
