1/2C X 3/4 FPT COP ADAPT

1/2" C x 3/4" FPT Copper Adapter (COP ADAPT)

This is a copper-to-threaded transition fitting used in plumbing to connect copper tubing to a threaded pipe or fixture.

What it is

A sweat-to-thread adapter with:

• 1/2" C (copper sweat end) — connects to 1/2" copper tubing using solder (sweat joint)
• 3/4" FPT (female pipe thread) — accepts a 3/4" male threaded fitting (NPT)

What it does

• Connects copper pipe to a larger threaded connection
• Allows transition from sweat (soldered copper) → threaded system
• Provides a removable threaded outlet connection

Key features

• Material: typically copper or copper alloy
• Connection types:
  • Sweat (C) end = solder joint
  • FPT end = female NPT threads
• Designed for pressure-rated plumbing systems

Common applications

• Water supply systems
• HVAC and mechanical piping
• Connecting copper lines to:
  • valves
  • pumps
  • fixtures
  • equipment with 3/4" male threads
