Eaton 05706B-1568 Barbed Hose Connector Brass Nptf

Product Description

The EATON 05706B-1568 is a brass barbed hose connector designed for fluid transfer applications in plumbing, HVAC, and light industrial systems. It features a 5/16 inch NPTF male threaded end on one side and a 3/8 inch ID hose barb on the other, creating a secure, leak-resistant transition between a threaded port and flexible hose. The NPTF thread form provides a pressure-tight mechanical seal without requiring additional sealant tape in many installations. Brass construction offers solid corrosion resistance for use with water, oil, and a range of common hydraulic and pneumatic fluids encountered in trade service work.

This connector is suited for residential and light commercial applications where a rigid threaded fitting must terminate into flexible hose. Typical uses include equipment plumbing connections, appliance water lines, HVAC condensate and fluid lines, and similar low-to-moderate pressure hose assemblies. It is installed by plumbers, HVAC technicians, and mechanical contractors working with standard flexible hose assemblies requiring a threaded transition point.

Key Features

• NPTF male thread at 5/16 inch for pressure-tight threaded port connections
• 3/8 inch ID hose barb end for secure grip on compatible flexible hose
• Brass construction provides corrosion resistance for water and fluid service
• Compact connector style for direct port-to-hose transitions without additional adapters

Compatibility

Designed as an OEM-style replacement or service fitting for fluid systems requiring a 5/16 inch NPTF male threaded connection to 3/8 inch ID flexible hose.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician following applicable IPC or local plumbing code requirements. Shut off fluid supply and relieve system pressure before removing or installing any hose fitting. Verify hose ID matches the 3/8 inch barb diameter and secure the hose with an appropriate clamp to prevent blowoff under pressure. Inspect the NPTF threads for damage before assembly and confirm a proper seal before returning the system to service.
