Coupling Configuration
Female NPT Connection
One end features a precision-machined female NPT connection for installation with a compatible male-threaded pipe, nipple, fitting, valve, or equipment connection.
Straight Coupling Body
The center body provides a direct in-line connection while maintaining the selected nominal pipe size through the coupling.
Female NPT Connection
The opposite end also features a female NPT connection for joining another compatible male-threaded piping component.
Construction Details
Midland Aluminum Threaded Couplings are manufactured from quality aluminum to provide a dependable balance of mechanical strength, low weight, and corrosion resistance.
Precision-machined female NPT threads on both ends help provide consistent engagement with compatible threaded piping components when installed using accepted piping practices.
The lightweight straight-body design provides a simple method for extending, joining, or repairing threaded pipe runs where aluminum fittings are appropriate for the intended service.
Why Choose an Aluminum Threaded Coupling?
Simple In-Line Connection
- Joins two male-threaded components
- Maintains the same nominal pipe size
- Useful for extending threaded pipe runs
- Suitable for repairs and modifications
- Compact one-piece fitting design
Lightweight Aluminum Construction
- Reduces overall system weight
- Provides corrosion resistance in compatible environments
- Easier handling than heavier metal fittings
- Suitable for pneumatic and utility systems
- Useful where aluminum fittings are specified
NPT Threaded Connections
Female NPT x Female NPT
Both ends use female NPT threads for connection to compatible male NPT pipe, nipples, fittings, valves, or equipment components.
Thread Sealing
Use an approved thread sealant or PTFE tape on mating male NPT threads according to the piping material, system media, and installation requirements.
Typical Applications
Pneumatic & Utility
- Compressed air systems
- Pneumatic piping
- Utility piping
- Equipment connections
- General threaded piping systems
Industrial & Marine
- Industrial piping systems

What material are these couplings made from?
They are manufactured from aluminum.
What type of connections do they use?
They use female NPT threaded connections on both ends.
What is an aluminum threaded coupling used for?
It is used to join two compatible male-threaded pipe, nipple, fitting, valve, or equipment connections in a straight line.
Does the coupling change pipe size?
No. These are straight couplings intended to connect compatible components of the same nominal pipe size.
Why choose aluminum?
Aluminum provides a lightweight, corrosion-resistant alternative to heavier metal fittings when it is compatible with the intended media and piping system.
Can these be used in compressed air systems?
The supplied product information identifies compressed air and pneumatic systems among the intended applications.
Should thread sealant be used?
Use an approved thread sealant or PTFE tape on mating male NPT connections according to the application requirements.
Can these couplings be used with water?
The supplied product information identifies water and other compatible fluid transfer systems as possible applications where aluminum is suitable.
What should I know about galvanic corrosion?
When aluminum contacts certain dissimilar metals in the presence of an electrolyte, galvanic corrosion may occur. Confirm material compatibility and use appropriate system protection where required.
What should I verify before ordering?
Confirm nominal pipe size, both mating male NPT connections, pressure, temperature, media compatibility, installation environment, and material compatibility.
