Eaton 05705B-102 Barbed Hose Fitting 1/8 in Nptf Brass

Product Description

The EATON 05705B-102 is a male rigid barbed hose fitting manufactured from brass, designed to create a secure threaded-to-hose connection in fluid transfer and pneumatic plumbing applications. The fitting threads in at 1/8 inch NPTF on the male end and accepts hose with a 5/16 inch inside diameter on the barbed end. The NPTF thread form provides a pressure-tight seal without requiring a separate sealant in many applications, though thread tape or compound is commonly used in the field. At 1.23 inches overall length and weighing just 0.01 pounds, this compact fitting is a standard component in low-pressure hydraulic, pneumatic, and fluid-line assemblies.

This fitting is suited for residential and light commercial plumbing, HVAC condensate and refrigerant-line accessories, pneumatic control tubing, and general fluid transfer lines where a 1/8 inch NPTF male thread is required on one end and a barbed push-on hose connection is needed on the other. Licensed plumbers, HVAC technicians, and pipefitters regularly use fittings of this type when routing flexible hose from a threaded port on a valve, sensor, or equipment manifold.

Key Features

• NPTF thread standard provides a pressure-tight mechanical seal at the threaded connection
• Brass construction offers corrosion resistance and durability in wet and humid environments
• Rigid male fitting design locks securely to the mating threaded port
• Barbed end accepts 5/16 inch ID hose for a grip-fit connection without additional fittings
• Compact 1.23 inch overall length fits in tight equipment spaces
• 0.44 inch hex head allows standard wrench installation and removal

Compatibility

Designed as an OEM-style replacement or standard service fitting for applications requiring a 1/8 inch NPTF male thread with a 5/16 inch ID hose barb connection.

Installation Notes

This fitting is typically installed by licensed plumbers or HVAC technicians. Shut off system pressure and bleed the line before removing or installing any hose fitting. Apply NPTF-compatible thread sealant tape or compound to the male threads before installation. Use a wrench on the 0.44 inch hex head to tighten to snug-plus-turns per standard practice — do not overtighten brass fittings, as the material is subject to thread damage under excessive torque.
