Copper Sweat Fitting Elbow

This NIBCO 606 elbow joins two 5/8-inch copper tubes at a 45-degree angle using cup-to-cup sweat connections. It is made from wrot copper and rated for air, gases and potable water systems. The fitting suits plumbers and HVAC installers who need a standard directional change in copper pipework.

Simple Sweat Installation

The cup ends slide over clean, fluxed tube and are soldered with a torch; no threading, pressing or special tools are required beyond normal sweating practice. Leaks usually come from insufficient cleaning, poor flux coverage or overheating the joint. Correct tube preparation and even heat avoid most callbacks.

Pressure And Temperature Headroom

The elbow withstands up to 631 psi at 100 °F and continuous temperatures up to 400 °F, giving ample margin for typical residential hot-water and low-pressure gas lines. It runs out of headroom in high-pressure steam or industrial process piping that exceeds either limit.
