Bronze return-bend coupling with two cup ends

Nibco, Inc.

Nibco, Inc. 701-D-LF 3/4 Return Bend Bronze Coupling

SKU CH-VX6W-29RS0

Bronze sweat coupling joins two 3/4 in copper tubes in potable water systems up to 466 psi and 200 Degrees F

  • Sweat-fit design enables quick copper tube installation
  • Bronze construction resists corrosion in potable water systems
  • Pressure rated to 466 psi for reliable supply lines
  • Operates up to 200 Degrees F for hot water service
  • Lead-free alloy meets safe drinking water standards

Application & Sizing

This bronze coupling is built for potable-water lines and joins two 3/4 in copper tubes with cup ends on both sides. The D-shaped return-bend profile routes the pipe back toward its source in tight mechanical rooms or retrofit runs. Rated to 466 psi and 200 Degrees F, it handles standard residential and light-commercial pressure and temperature demands. No centre stop means the tubes can slide fully through for easier alignment during assembly.

Who This Suits & Who It Does Not

Installers sweating copper for domestic hot and cold distribution will find the dimensions and pressure class a direct match. Systems that require a built-in depth stop, press-connect or threaded transitions, or pipe sizes other than 3/4 in copper must use a different fitting. The bronze body is not intended for gas, fuel-oil or high-purity process piping where material approvals differ.

Deciding Specification

The sweat cup-to-cup connection on 3/4 in copper tube outer diameter 7/8 in is the single detail that determines fit; verify the tube size and joining method before ordering.

Questions about this item

How does the 466 psi pressure rating hold up once the coupling is soldered into a copper water line?

The 466 psi maximum operating pressure applies to the installed joint, so the bronze body and sweat connections are designed to handle that pressure in service.

What does the sweat cup connection mean for the joint, and what temperature limit does it impose?

Sweat cups require soldering to 3/4 in copper tube, and the assembly is rated for a maximum operating temperature of 200 Degrees F.

What tube size and centre-stop arrangement does this return bend need to fit correctly?

It fits 3/4 in copper tube with a 7/8 in outside diameter on both ends and has no centre stop, so the tubes can slide fully through.
