Description
Midland Black API Line Pipe Coupling - Female NPT
Midland Black API Line Pipe Couplings provide a straight threaded connection between compatible male-threaded steel pipe sections. These black steel couplings are offered in nominal sizes from 1/8" through 8" for industrial, mechanical, and line-pipe applications.
The full-coupling design provides female threaded connections on both ends, allowing two compatible threaded pipe sections or components of the same nominal size to be joined inline.

What Is an API Line Pipe Coupling?
An API line pipe coupling is a straight threaded fitting used to connect two compatible male-threaded pipe sections of the same nominal size.
- Provides a straight inline threaded connection
- Female threads on both ends
- Joins matching nominal pipe sizes
- Available in a broad range of steel pipe sizes
- Useful for industrial and line-pipe assemblies
Full Coupling vs. Half Coupling
Full API Coupling
A full coupling connects two compatible male-threaded pipe sections inline, with female threaded connections on both ends.
Half Coupling
A half coupling provides a shorter threaded connection and is commonly incorporated into fabricated piping, vessels, tanks, and equipment assemblies.

Common Applications
Mechanical & Utility Piping
- Threaded steel pipe systems
- Mechanical rooms
- Utility piping
- Equipment connections
- Maintenance and repair
- General threaded piping
Industrial & Line Pipe
- Industrial piping systems
- Plant piping
- Line-pipe assemblies
- Production facilities

How to Select the Correct API Coupling
- Step 1: Identify the nominal pipe size.
- Step 2: Confirm both mating components use the same nominal size.
- Step 3: Confirm a full female-threaded coupling is required.
- Step 4: Select the matching Midland API part number.
- Step 5: Verify the coupling is appropriate for the piping system and application.

Installation Guidance
- Verify nominal pipe size before installation.
- Inspect the coupling and mating pipe threads for damage or contamination.
- Use thread sealant appropriate for the piping application.
- Start each connection carefully to avoid cross-threading.
- Use appropriate tools and tightening procedures.
- Avoid excessive torque that could damage the coupling or mating pipe.
- Provide adequate support for larger piping sizes.
- Test the completed system according to applicable requirements.
Our pipe, fitting, and industrial product specialists can help review your nominal pipe size, API coupling requirements, female thread connection, piping layout, mating pipe, and industrial application before you order.
