Nibco, Inc. 607LT 7/8" copper 90° long radius elbow

SKU CH-ARKA-9T7MJ

A 7/8-inch copper 90-degree long-radius elbow for sweat connections in air, gas and potable-water lines, rated to 395 psi at 200 °F and 400 °F maximum temperature

  • Long-radius bend for smooth flow in tight spaces
  • 90° copper elbow joins 7/8 in tubes with sweat connections
  • Wrot copper construction handles 395 psi at 200°F
  • Rated for air, gases and potable water systems
  • Operates reliably up to 400°F maximum temperature

Copper plumbing elbow for potable-water systems

This 7/8 inch copper long-radius elbow joins two copper tubes of the same size using sweat connections on both ends. It is suited for air, gases and potable-water lines in residential or light-commercial installations. The fitting is manufactured by NIBCO from wrot copper and carries the 607LT designation. Condition is new and ready for installation.

Pressure and temperature ratings for normal service

The elbow is rated for a maximum operating pressure of 395 psi at 200 degrees F and a maximum operating temperature of 400 degrees F. These limits cover typical hot-water and compressed-air circuits without requiring derating. The long-radius geometry promotes smooth flow and reduces turbulence compared with short-radius alternatives. No special thermal or acoustic considerations apply to the fitting itself.

Sweat connections and material implications

Both ends present a cup-style sweat connection for 7/8 inch nominal copper tube, which has a one inch outer diameter. Installers must clean, flux and solder each joint using standard copper-joining practice. The wrot copper body resists corrosion in potable-water service and is compatible with common flux and solder alloys. The 90 degree long-radius bend allows gradual direction changes in tight runs without sharp kinks.

Questions about this item

How do I sweat the 7/8" cup ends onto copper tube without getting a leak at the joint?

Clean the tube end and cup with emery cloth, apply flux, slide the 90 degree long radius elbow on, heat the cup evenly until solder flows into the joint, then wipe while warm; the most common mistake is heating the tube instead of the cup so solder never fully penetrates.

What maintenance or replacement will the wrot copper elbow need after installation in a potable water system?

Wrot copper does not degrade in potable water; no scheduled replacement is required unless the system is altered or a leak appears at a sweat joint.

At what temperature does the 395 psi pressure rating cease to apply during sustained hot water circulation?

The 395 psi rating is specified at 200 °F; above that temperature the allowable pressure drops, and the absolute maximum operating temperature is 400 °F.
