A copper 90-degree long-radius elbow with smooth solder-cup ends

Nibco, Inc.

Nibco, Inc. U607LT 90° long radius elbow 1-1/4 in C x C

SKU CH-8Q1D-6F4VV MPN U607LT

Connects copper tubing at a 90-degree angle with a long-radius bend for smooth flow in plumbing systems

  • TypeDrain Components
  • Long-radius design reduces flow restriction
  • Wrought copper construction resists corrosion
  • C x C solder joints create leak-free connections
  • Rated 439 psi at 100 Degrees F for high-pressure systems
  • Meets ASME/ANSI B 16.22 standard for code compliance

Copper 90-degree long-radius elbow

The Nibco U607LT is a wrot copper fitting that joins two 1-1/4 inch copper tubes with a C x C sweat connection. Plumbers and HVAC installers use it to change direction in hydronic heating, chilled-water or domestic-water systems where a long-radius bend reduces pressure drop.

Pressure and temperature ratings

The elbow is rated for 439 psi at 100 degrees F and operates continuously from -20 degrees to 400 degrees F. Copper construction resists corrosion in closed-loop water and glycol circuits without adding measurable flow restriction.

Sustained high-temperature service

Under prolonged exposure to the upper end of its temperature range the fitting maintains its pressure rating without deformation. The ASME B16.22 compliance confirms dimensional stability for the life of the piping system.

Questions about this item

How do I install the 1-1/4 in C x C copper elbow and what step is often missed?

Clean both tube ends and the fitting sockets, apply flux, insert tubes fully, then sweat the joints with lead-free solder; the step often missed is removing all flux residue after cooling to prevent long-term corrosion.

What maintenance or replacement will the wrot copper elbow need over time?

The fitting itself requires no scheduled maintenance; inspect joints periodically for green patina or leaks, and replace only if a joint fails or the system is re-piped.

At what pressure limit does the 90° long radius elbow reach its rating during sustained hot-water use?

The elbow is rated to 439 psi at 100 °F; pressure capacity decreases as temperature rises toward the 400 °F maximum, so the effective limit under sustained high-temperature use is lower than 439 psi.
