Copper Coupling for 2-1/2" Pipe

The Legend Valve 450-509 is a C x C copper coupling designed to join two sections of 2-1/2" inner diameter pipe. It suits plumbers and maintenance crews who need a straightforward sweat fitting for water supply lines.

Fits standard copper tubing

The coupling accepts 2-1/2" ID tubing with a 2-5/8" outer dimension, allowing a direct soldered connection without adapters. Its transparent finish lets the installer verify solder flow around the full circumference.

Questions about this item

What is the maximum temperature this 2-1/2" copper coupling can withstand under continuous hot-water flow?

The copper construction handles typical residential hot-water temperatures without degradation, and the fitting meets standard plumbing code requirements for continuous service.

Does the coupling generate noise or heat when water runs through it all day?

No, the solid copper body has no moving parts, so it operates silently and does not produce heat beyond the water temperature itself.

What pipe material and tools are needed to install this C x C coupling?

You need 2-1/2" copper pipe, flux, lead-free solder, a propane or MAPP torch, and a pipe cutter or hacksaw for clean, square cuts.
