Value Brand 6AFJ5 Hose Barb 1 in x 3/4 in Brass

Fitting for air-powered tools

This brass hose barb connects a 1-inch hose to a 3/4-inch male NPT thread on air-powered tools and compressors. The straight, polished fitting uses a beaded barb design for a secure push-on connection. It is supplied new as a single-use component rated for 300 psi at 70 degrees Fahrenheit. The brass-on-brass construction resists corrosion in typical workshop environments.

Pressure capacity and limits

The fitting handles up to 300 psi maximum working pressure at 70 degrees Fahrenheit, which covers most standard shop compressors and pneumatic tools. Performance above that pressure or at higher temperatures is not rated, so the fitting should not be used in high-pressure or high-heat systems. It is designed for one-time installation rather than repeated assembly and disassembly. The 1-inch by 3/4-inch size suits common air-line diameters.

Temperature and installation notes

The 300 psi rating is specified at 70 degrees Fahrenheit; pressure capacity may decrease as temperature rises. Brass material conducts heat quickly, so the fitting will reach fluid temperature rapidly during use. No dynamic seals or moving parts are present, so the fitting adds no mechanical noise to the air system. California Proposition 65 warnings apply because the brass contains chemicals known to cause cancer and reproductive harm.
