3/8 GALV COUP

3/8" Galvanized Coupling (3/8 GALV COUP)

This is a standard threaded pipe fitting used to connect two pieces of 3/8-inch pipe in a straight line.

What it is

A galvanized steel coupling:

• Has female internal NPT threads on both ends
• Designed for 3/8" male threaded pipe

What it does

• Connects two 3/8" pipes together
• Extends a pipe run in a straight line
• Creates a permanent, sealed threaded joint

Key features

• Material: galvanized steel (zinc-coated for corrosion resistance)
• Connection type: female threaded both ends (NPT)
• Design: straight coupling (no size change)
• Used for same-size pipe extension

Common applications

• Water and air piping systems
• HVAC and mechanical piping
• Industrial and utility piping runs
• General pipe extension or repair work

Quick distinction

• COUP (coupling) = same size to same size (3/8 to 3/8)
• RED COUP (reducing coupling) = different sizes (like 3/8 to 1/4)
