Eaton 05705B-C04 Brass Barbed Elbow Hose Fitting

Product Description

The EATON 05705B-C04 is a brass barbed elbow hose fitting designed to connect flexible hose to threaded ports in fluid-handling and pneumatic systems. The elbow configuration allows a 90-degree directional change, making it well suited for tight routing in confined spaces. One end features a 1/4 inch NPTF male threaded connection, while the other end provides a 5/16 inch ID barbed connection for securing flexible hose. At 1.4 inches overall length with a barb size of 0.3125 inches, this compact fitting delivers a reliable, leak-resistant seal. Plumbers, HVAC technicians, and general mechanical contractors install this type of fitting in low-pressure fluid lines and pneumatic circuits.

This fitting is appropriate for residential and light commercial applications where flexible hose must transition to a threaded port at a right angle. Typical uses include water supply lines, pneumatic tool connections, fuel lines, and coolant circuits. The NPTF thread standard provides a pressure-tight mechanical seal without relying on a separate sealant tape, though thread sealant is commonly applied per installation requirements. The brass construction offers good corrosion resistance across a range of compatible media.

Key Features

• Elbow body allows 90-degree directional routing in confined plumbing or pneumatic runs
• 1/4 inch NPTF male thread provides a dry-seal, pressure-tight threaded connection
• 5/16 inch ID barb sized at 0.3125 inches secures flexible hose without additional fittings
• Brass construction resists corrosion and withstands typical fluid and air service environments
• Compact 1.4 inch overall length suits tight installation clearances

Compatibility

Designed as an OEM-style replacement or new-installation fitting for flexible hose with a 5/16 inch inside diameter and systems with 1/4 inch NPTF threaded ports.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified mechanical contractors. Shut off and relieve pressure from the line before removing or installing any fitting. Apply an appropriate thread sealant to the NPTF male threads per the system manufacturer and local code requirements. Secure the barbed end by pressing the hose fully over the barb and use an appropriate clamp to retain the hose under service pressure.
