2 x 1 CXC Red Copper Coupling

This Legend Valve 450-546 coupling joins 2" and 1" copper pipes in a sweat-to-sweat configuration. It suits plumbers and DIYers making a permanent size transition on water supply lines. The red colour identifies the fitting quickly among other components. The item is new and ships directly from the manufacturer.

Installation and common issues

Clean and flux both pipe ends before sliding them fully into the coupling sockets. Apply even heat with a propane torch until the solder flows around each joint. A frequent mistake is insufficient pipe insertion, which leaves a gap that leaks under pressure. Another error is overheating, which can burn the flux and prevent a sound seal.

Pre-order checks

Verify that your existing pipes measure 2" and 1" nominal size and are copper, not steel or plastic. Confirm the system is drained and depressurised before cutting. Check local code for any restrictions on lead-free solder requirements. Note the California Proposition 65 warning regarding chemicals known to cause cancer and reproductive harm.
