Nibco, Inc.

Nibco, Inc. 701D-LF 1/2 in Drain Coupling Bronze

SKU CH-3BAY-3FPB2

A bronze sweat coupling joins two 1/2-inch copper tubes for potable water at up to 577 psi and 200 degrees F

  • Lead-free bronze keeps potable water safe
  • Sweat-cup connections create permanent leak-free joints
  • 577 psi rating handles high-pressure supply lines
  • 200 °F tolerance suits hot-water systems
  • No centre stop allows full drainage flow

1/2 in Bronze Drain Coupling

This sweat fitting joins two 1/2 in copper tubes for potable water lines. The bronze body handles a maximum operating pressure of 577 psi and a maximum operating temperature of 200 Degrees F. It is supplied new and ready for solder installation.

Pressure and temperature limits

The coupling is rated for 577 psi at up to 200 Degrees F in normal service. No moving parts or powered components are present, so there is no noise or power draw associated with the fitting itself. Performance depends on proper soldering technique and system design.

No centre stop included

The fitting omits a centre stop, so the installer must gauge insertion depth during assembly. No additional accessories, sealants or software are bundled with the product. Orders of $75 or more from the supplier qualify for free shipping.

Questions about this item

How do I install this 1/2 in sweat fitting coupling on copper tube, and what step is often missed?

Clean the 5/8 in tube ends and the cup interiors, apply flux, slide the coupling onto both tubes, then heat evenly with a torch until solder flows into the joint; the step often missed is heating both cups uniformly so the solder draws through the center stop area.

What maintenance or replacement will this bronze drain coupling need over time?

Bronze resists corrosion in potable water, so no routine maintenance is required; inspect joints during system checks and replace only if a leak develops or the fitting is damaged during a repipe.

What limit appears first when this coupling runs at sustained pressure and temperature?

The maximum operating pressure of 577 psi is the primary limit; sustained exposure near 200 Degrees F reduces the allowable pressure, so design the system to stay below the rated pressure at the actual operating temperature.
