Eaton 05706B-102 Barbed Hose Fitting 1/8 Nptf X 3/8 Id Brass

Product Description

The EATON 05706B-102 is a male rigid barbed hose fitting machined from brass, designed to create a secure, leak-resistant connection between threaded pipe and flexible hose in fluid-handling systems. The male end features a 1/8 inch NPTF thread, which provides a pressure-tight mechanical seal without the need for additional sealant tape in many applications. The barbed end accepts 3/8 inch inside diameter hose. With an overall length of 1.34 inches and a hex head size of 0.5 inches, this fitting is compact and compatible with standard wrenches. Plumbers, HVAC technicians, and fluid-system installers use this type of fitting in low-pressure lines, equipment connections, and instrumentation tubing runs.

This fitting is suited for residential and light commercial applications where a rigid threaded-to-hose transition is required. Typical installations include connecting flexible tubing to threaded ports on pumps, valves, condensate systems, and similar fluid-handling equipment. The NPTF thread standard makes it appropriate for use in systems that require a dry-seal threaded connection. The brass construction handles water, air, and a range of compatible fluids found in HVAC, plumbing, and general mechanical service work.

Key Features

• 1/8 inch NPTF male thread provides a dry-seal, pressure-tight connection
• 3/8 inch inside diameter barb secures flexible hose without additional fittings
• Brass construction offers corrosion resistance in wet and fluid-handling environments
• Compact overall length of 1.34 inches suits tight installation spaces
• 0.5 inch hex head allows engagement with standard open-end or adjustable wrenches
• Barb size of 0.375 inches retains hose securely under normal working pressures

Compatibility

Designed as an OEM-style replacement or direct-install brass barbed hose fitting for systems using 1/8 inch NPTF threaded ports and 3/8 inch inside diameter flexible hose.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable IPC or IFGC guidelines. Shut off fluid supply and relieve system pressure before removing or installing any fitting. NPTF threads are designed to seal on the thread form itself; inspect threads for damage before installation and apply thread sealant only as required by system specifications. Do not overtighten — use a wrench on the hex head only, and avoid torquing against the hose barb.
