Nibco, Inc. 7076-LF 3/4 Union Elbow 90 Deg C x C

SKU CH-V2JR-RHATK

A bronze sweat-fitting union elbow that joins two 3/4 in copper tubes at 90 degrees for potable water systems rated to 623 psi and 200 °F, meeting ASME B16.18, NSF/ANSI 61 and 372, and ISO 9001

  • Lead-free bronze meets NSF/ANSI 61 for safe potable water
  • 90-degree union elbow enables quick directional changes in copper lines
  • Rated 623 psi at 200 °F for demanding pressure and temperature service
  • Complies with ASME B16.18 and NSF/ANSI 372 for code-approved installations
  • Sweat cup-to-cup connections fit 3/4 in copper tube without threading

Application Scope

This bronze sweat fitting creates a 90-degree turn between two 3/4-inch copper tubes in potable water systems. It is intended for installers who need a removable union joint that can be disassembled for maintenance or equipment replacement.

Upgrade Path

The union elbow replaces a fixed sweat elbow when future access to the joint is required without cutting pipe. The change is worthwhile whenever a valve, pump or meter may need removal, because the union nut allows separation while the cup ends remain soldered in place.

Standard Limits

The fitting conforms to ASME B 16.18 dimensions and carries NSF/ANSI 61 and 372 certifications for potable water contact. Its pressure rating of 623 psi and temperature rating of 200 degrees F define the maximum service conditions; systems operating beyond those limits must use a different fitting class.

Questions about this item

What copper tube size does each cup connection of the 7076-LF union elbow accept?

Each cup connection fits 3/4 in copper tube with a 7/8 in outer diameter, so both ends match the same tube size for a 90-degree turn.

How is the 7076-LF union elbow installed, and what step is often missed?

The fitting is sweat-soldered onto clean, fluxed copper tube; the common error is forgetting to disassemble the union nut and gasket before heating, which can damage the seal.
