Nibco b02980l 3/4 in Drop Ear Straight Adapter Copper

Product Description

The NIBCO b02980l is a 3/4 inch cast copper drop ear straight adapter designed to transition from a sweat (solder) connection to a female threaded connection while providing a mounting ear for wall or framing attachment. Lead-free construction meets current potable water standards. The drop ear design secures the fitting to a backing plate or stud, eliminating movement at the connection point. This adapter is installed by licensed plumbers and experienced pipefitters in residential and light commercial plumbing systems.

This fitting is suited for water supply applications where a copper sweat line terminates at a fixed wall outlet, such as shower arms, tub spouts, or wall-mounted fixture supplies. The integral ear allows the fitting to be screwed directly to blocking or framing before the finished wall is closed, providing a stable, no-movement base for threaded fixture connections. It is commonly used during rough-in plumbing on new construction and remodel projects.

Key Features

• Lead-free cast copper construction meets potable water installation requirements
• Drop ear mounting flange secures fitting to wall blocking or framing to prevent rotation and stress on solder joint
• 3/4 inch sweat inlet accepts standard copper tubing for soldered connection
• Female threaded outlet accepts standard male-threaded fixture or supply connections
• Cast copper body provides durability in concealed wall applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4 inch copper sweat plumbing systems requiring a fixed female threaded wall outlet.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and all applicable local codes. Shut off the water supply and relieve system pressure before soldering. Clean and flux all sweat connections before applying heat, and allow the joint to cool completely before handling. Secure the mounting ear to solid blocking or backing before closing the wall to ensure the fitting does not shift under load.
