Eaton 05706B-C04 Brass Barbed Elbow Fitting 1/4 Nptf

Product Description

The EATON 05706B-C04 is a brass barbed elbow hose fitting designed for connecting flexible hose to a threaded port at a 90-degree angle. It features a 1/4-inch male NPTF threaded end and a 3/8-inch barbed end sized for hose with a 3/8-inch inside diameter. The NPTF thread form creates a pressure-tight mechanical seal without requiring additional sealant, though thread tape or compound is commonly applied. At 1.46 inches overall length and 0.01 pounds, this compact fitting is suited for tight routing applications in fluid transfer, pneumatic, and low-pressure hydraulic lines across HVAC, plumbing, and industrial service work.

This fitting is appropriate for residential and light commercial applications where a barbed hose connection must transition to a male NPTF threaded port. Typical installation scenarios include equipment drain lines, coolant routing, compressed air accessories, and water supply connections where flexible hose must change direction. It is installed by licensed plumbers, HVAC technicians, and maintenance professionals working on fluid-handling systems that require a reliable right-angle hose-to-thread transition.

Key Features

• Brass construction resists corrosion in water and air service applications
• 1/4-inch male NPTF thread provides a pressure-tight mechanical seal at the threaded port
• 3/8-inch barb accepts hose with 3/8-inch inside diameter for a secure friction grip
• Elbow configuration routes hose at 90 degrees for use in confined or tight-clearance installations
• 1.46-inch overall length keeps the fitting compact within assemblies
• Barb size of 0.375 inches ensures positive hose retention with or without a clamp

Compatibility

Designed as an OEM-style replacement or service fitting for fluid and air systems requiring a 1/4-inch NPTF male thread to 3/8-inch ID barbed hose elbow connection.

Installation Notes

Installation should be performed by a qualified plumber or HVAC technician. Depressurize and drain the system before removing or installing any fittings. Apply NPTF-rated thread sealant tape or compound to the male threads before assembly to ensure a leak-free seal. Do not overtighten; hand-snug plus a controlled turn with a wrench is typical for brass fittings to avoid cracking the hex body.
