1/2 X 1/8 FTG X FPT BUSHING

1/2" x 1/8" FTG x FPT Bushing (Reducing Adapter Bushing)

This is a plumbing transition fitting used to connect a copper sweat connection to a threaded connection while reducing size.

What it is

A reducing bushing/adaptor with two different ends:

• 1/2" FTG (female sweat socket) — fits over 1/2" copper tubing
• 1/8" FPT (female pipe thread) — accepts a 1/8" male threaded fitting

What it does

• Connects copper tubing to threaded piping/components
• Reduces the connection size down to 1/8" threaded outlet
• Allows transition from sweat (solder) system → threaded system

Key features

• Material: typically copper or brass (depending on manufacturer/application)
• Connection types:
  • FTG = solder/sweat connection
  • FPT = female threaded connection (NPT standard)
• Function: inline reducer + threaded adapter in one fitting

Common uses

• Water or HVAC control lines
• Instrumentation or sensor connections
• Small branch lines off copper piping
• Systems requiring transition to small threaded valves, gauges, or fittings
