Eaton 05705B-C02 Brass Barbed Elbow Fitting 1/8 Nptf

Product Description

The EATON 05705B-C02 is a brass barbed elbow hose fitting designed for low-pressure fluid and pneumatic line connections in HVAC, plumbing, and general industrial applications. It features a 1/8 inch male NPTF threaded end on one side and a 5/16 inch ID barbed end on the other, forming a 90-degree elbow transition between rigid threaded ports and flexible hose. The NPTF thread form provides a dry-seal connection that resists leakage without sealant tape in many applications, though thread sealant is still recommended per standard practice. The brass construction offers good corrosion resistance in water, oil, and air service. Licensed plumbers, HVAC technicians, and pipefitters are the typical installers for this fitting type.

This fitting is suited for residential and light commercial installations where a 90-degree direction change is needed between a threaded port and a flexible hose line. Common applications include condensate drain lines, refrigeration oil lines, fuel lines, and pneumatic control tubing where 5/16 inch ID hose must connect to a 1/8 inch NPTF port. The compact overall length of 1.18 inches makes it practical in tight equipment enclosures and control panels where clearance is limited.

Key Features

• 1/8 inch male NPTF dry-seal thread for leak-resistant port connections
• 5/16 inch ID barb end sized for standard 5/16 inch ID flexible hose
• Elbow geometry enables 90-degree direction changes in confined spaces
• Compact overall length of 1.18 inches fits tight equipment enclosures
• UNSPSC Code 40141734 for procurement system compatibility

Compatibility

Designed as an OEM-style replacement barbed elbow fitting for systems using 1/8 inch NPTF threaded ports and 5/16 inch ID flexible hose connections in HVAC, plumbing, and pneumatic control applications.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified pipefitter. Shut off all system pressure and depressurize the line before removing or installing any fittings. Apply an appropriate thread sealant or PTFE tape to the NPTF threads per job requirements and local code, even though NPTF threads are designed for dry-seal service. Secure the hose barb end with an appropriate clamp to prevent blowoff under operating pressure.
