Nibco, Inc. 714LF-1 Sweat Fitting Tee 1 in C x 1 in FNPT x 1 in C Cast Bronze

SKU CH-HFN7-WVZJX MPN 714LF-1

A lead-free cast bronze sweat tee connects 1 in copper tube to 1 in FNPT and 1 in copper tube, rated 395 psi and 200 °F for potable water

  • TypeDrain Components
  • MaterialHAWA
  • Lead-free cast bronze for potable water safety
  • 395 psi rating handles high-pressure supply lines
  • 200 °F maximum temperature suits hot-water systems
  • Cup x FNPT x Cup layout connects copper and threaded pipe
  • Sweat and threaded ends enable versatile installation

Application and Use

This cast bronze sweat fitting tee connects one-inch copper tubing to a one-inch FNPT threaded port for potable water lines. It suits plumbers and maintenance crews who need a lead-free transition between soldered and threaded pipe sections.

Pressure and Temperature Limits

The fitting handles up to 395 psi and 200 degrees F in normal service, providing a reliable seal for hot and cold distribution without deformation or leakage at the joints.

Sustained Service Behaviour

Under continuous pressure and thermal cycling the bronze body maintains dimensional stability and resists dezincification, so the sweat and threaded connections stay tight without the stress relaxation seen in short-term test bursts.

Questions about this item

How do I install the 1 in sweat copper connections on the 714LF-1 tee?

Clean the 1 1/8 in tube ends and fitting cups, apply flux, insert tubes fully, then heat evenly with a torch until solder flows into each joint. The step often missed is heating the fitting cup — not just the tube — so solder pulls into the joint by capillary action.

What maintenance or replacement will the cast bronze tee need over time?

The low-lead cast bronze body resists corrosion in potable water, so no scheduled replacement is required. Inspect joints annually for green patina or seepage; if a joint weeps, re-sweat that connection rather than replacing the entire tee.

What limit appears first when the tee runs at sustained pressure and temperature?

The 395 psi maximum operating pressure is reached before the 200 °F temperature limit in most hot-water systems, so pressure spikes from thermal expansion or pump surge become the governing constraint.
