1/8 GALV COUP

1/8" Galvanized Coupling (1/8 GALV COUP)

This is a small threaded pipe fitting used to connect two pieces of 1/8-inch pipe in a straight line.

What it is

A galvanized steel coupling:

• Has female internal NPT threads on both ends
• Designed for 1/8" male threaded pipe

What it does

• Connects two 1/8" pipe sections together
• Extends a piping run in a straight line
• Creates a sealed, leak-resistant threaded joint

Key features

• Material: galvanized steel (zinc-coated for corrosion resistance)
• Connection type: female threaded both ends (NPT)
• Design: straight coupling (same size both ends)
• Used for very small-diameter piping systems

Common applications

• Instrumentation and control lines
• Air and water control circuits
• Gauge and sensing systems
• Small mechanical or HVAC piping runs

Quick note

• COUP = same size connection (1/8 to 1/8)
• RED COUP = different size reduction
