Eaton 05704B-102 Barbed Hose Fitting 1/8 Nptf Brass

Product Description

The EATON 05704B-102 is a male rigid barbed hose fitting machined from brass, designed to connect 1/4 inch inside diameter hose to a 1/8 inch NPTF threaded port. The barbed end creates a secure mechanical grip on the hose, while the threaded male end seals into a female NPTF port. At 1.06 inches overall length with a 0.44 inch hex head, this compact fitting is well suited for tight installations. Plumbers, HVAC technicians, and fluid-system assemblers use fittings like this in low-pressure fluid and pneumatic lines where a reliable, leak-resistant threaded-to-hose transition is required.

This fitting is appropriate for residential and light commercial applications involving 1/4 inch ID flexible hose routed to threaded equipment ports. Typical use cases include condensate drain lines, water supply branches, pneumatic control tubing, and similar low-pressure service lines. The NPTF thread form provides a dry-seal connection that reduces reliance on additional thread sealant, though most installers apply PTFE tape or pipe sealant per job requirements and applicable codes.

Key Features

• Brass construction resists corrosion in water, air, and mild fluid service
• 1/8 inch NPTF male thread for dry-seal threaded port connections
• Barbed end sized for 1/4 inch inside diameter hose
• 0.44 inch hex head allows standard wrench installation
• Compact 1.06 inch overall length suits confined spaces
• Male rigid configuration — no swivel; orient hose run before tightening

Compatibility

Designed as an OEM-style replacement or service fitting for any system using 1/4 inch ID flexible hose terminating at a 1/8 inch NPTF female threaded port.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Depressurize and drain the line before removing or installing any fitting. Apply PTFE tape or an approved pipe thread sealant to the male NPTF threads before assembly. Because this is a male rigid fitting, route and position the hose before final tightening to avoid twisting or stressing the hose.
