Copper elbow for potable water lines

This 90-degree sweat fitting joins 1-inch copper tube to a 1-inch male NPT thread. It is certified to NSF/ANSI 61 and NSF/ANSI 372 for drinking water safety. The cast copper body meets ASME B16.18 and ISO 9001 standards. Installers who need a lead-free directional change at the supply line will use this part.

Pressure and temperature limits

The fitting is rated for a maximum operating pressure of 395 psi and a maximum operating temperature of 200 degrees Fahrenheit. These limits define the safe envelope for hot and cold water distribution. Systems that exceed either value require a different component. The standards listed do not extend the ratings beyond these figures.

Cast copper construction

The cup end accepts 1-inch copper tube with an outside diameter of 1 1/8 inches for a soldered joint. The opposite end provides 1-inch MNPT threads for connection to threaded valves or equipment. Cast bronze material resists dezincification in potable water. The 90-degree fixed angle determines the piping layout and cannot be adjusted after installation.

Questions about this item

Should I choose the 1 in C x MNPT version or a different size?

This model is a 1 in C x MNPT 90° elbow with 1 1/8 in tube outer diameter on both sides, so select it when your copper tube and male pipe threads match those dimensions.

What does the 395 psi rating mean once the elbow is installed?

The 395 psi maximum operating pressure is the highest internal pressure the cast copper elbow can safely handle at up to 200 Degrees F in potable water systems.

Which standards apply to the ASME B 16.18 and NSF/ANSI 61 markings?

ASME B 16.18 covers cast copper alloy solder-joint fittings, while NSF/ANSI 61 and NSF/ANSI 372 certify the fitting for drinking water contact and low-lead compliance.
