Cast bronze reducing tee with three copper solder connections, matte metallic finish

Nibco, Inc.

Nibco, Inc. 712R Cast Bronze Reducing Tee 1-1/4 x 1-1/4 x 1/2 in

SKU CH-XPXN-JWY12

Connects three copper tubes at different diameters with cast bronze construction rated for 351 psi at 200 degrees F

  • Cast bronze body resists corrosion for long service life
  • Solder-joint ends create leak-tight copper connections
  • 351 psi at 200 °F handles demanding pressure lines
  • Rated from -20 °F to 400 °F for wide temperature range
  • Meets ASME B16.18 standard for reliable quality

Reducing Tee for Copper Piping

The Nibco 712R cast bronze reducing tee joins three copper tubes in a T configuration with solder-cup ends on each branch. It steps the third outlet down to a half-inch female pipe thread for fixture or valve attachment. The fitting suits residential and light-commercial water, heating and cooling circuits that require a durable, corrosion-resistant branch connection.

Pressure and Temperature Rating

Rated for 351 psi at 200 degrees Fahrenheit, the tee handles typical domestic hot-water pressures with ample margin. The service range spans minus 20 to 400 degrees Fahrenheit, covering chilled-water lines through high-temperature hydronic loops. Cast bronze construction avoids the thermal cycling fatigue that can crack lesser alloys.

ASME B16.18 Compliance and Threaded Outlet

Manufactured to ASME B 16.18, the fitting meets recognised dimensional and material standards for wrought copper-alloy solder-joint fittings. The half-inch FNPT branch accepts standard pipe-threaded adapters, valves or gauges without additional reducers. Solder cups on the two 1-1/4-inch runs allow direct capillary joining to matching tubing.

Questions about this item

How is the Nibco 712R reducing tee installed and which connection step is often done incorrectly?

The tee uses C x C x FNPT connections. Sweat the two 1-3/8 in copper ends with flux and lead-free solder; the 1/2 in FNPT branch requires pipe-thread sealant and careful hand-tightening plus one turn — over-tightening the female threads cracks the cast bronze body.

What maintenance or replacement will the Nibco 712R reducing tee need over its service life?

The cast bronze body and soldered joints are maintenance-free if installed correctly. Inspect the 1/2 in FNPT branch periodically for weeping; if thread sealant dries out or vibration loosens the joint, re-apply PTFE tape or pipe dope and re-tighten to stop the leak.

What is the first operating limit reached on the Nibco 712R reducing tee during sustained high-temperature use?

The pressure rating drops to 351 psi at 200 °F; as temperature climbs toward the 400 °F maximum, allowable pressure falls further, so the combined pressure-temperature envelope is the limiting factor before the bronze material itself degrades.
