💡 Why do professional plumbers prefer press fit copper couplers over standard pipe threaded fittings?

Copper press union systems simplify rough ins because the machine compression creates a permanent metal to metal bond.

- Eliminates messy thread sealing paste that often causes drips under pressure loads

- Delivers consistent torque readings so every single joint performs reliably over decades

- Keeps retrofits handy by skipping thread cutting tools that slow down installers
