Fitting Type and Application

This NIBCO bronze elbow is a sweat fitting designed for potable water systems. It connects a 1/2 inch copper tube to a 3/8 inch FNPT threaded pipe at a 90 degree angle. The drop ear shape allows secure mounting to a surface. It meets ASME B 16.18, ISO 9001, NSF/ANSI 372 and NSF/ANSI 61 standards.

Connection Compatibility Check

Verify that your existing piping uses 1/2 inch copper tube with a 5/8 inch outer diameter for the sweat side. Confirm the mating component has a 3/8 inch FNPT thread for the other side. Ensure the system operates within the 577 psi maximum pressure and 200 degrees F maximum temperature limits. This fitting is not for buyers who need a different tube size, thread size or connection method such as press or push fit.

Pressure and Temperature Performance

The bronze construction handles up to 577 psi and 200 degrees F in normal potable water use. Material grade C87850 provides corrosion resistance for long service life. No moving parts means silent operation without vibration or noise. The fitting adds no electrical load or power draw to the installation.

Questions about this item

Does the elbow come with any solder, flux or mounting hardware, or must those be purchased separately?

The fitting is supplied as a single bronze drop-ear elbow; solder, flux and any mounting screws or brackets are not included and must be bought separately.

Should I choose this 1/2 in cup by 3/8 in FNPT version or a different size for my supply line?

Select this model when the copper tube is 1/2 in CTS (5/8 in OD) and the mating thread is 3/8 in FNPT; other CTS or thread combinations require a different fitting.

What does the 577 psi rating mean when the elbow is installed in a household plumbing system?

It indicates the maximum continuous pressure the bronze body can withstand at up to 200 °F, well above typical residential supply pressures.
