Description
150# Black Malleable Right and Left Coupling
ASC 150# Black Malleable Right and Left Couplings are threaded fittings designed to join compatible right-and-left threaded pipe or nipples without rotating the connected piping.
The coupling uses opposing female thread directions, allowing both mating pipe ends to be drawn together as the coupling is turned. This makes it especially useful for repairs, replacements, and threaded piping installations where surrounding pipe cannot be rotated.

Construction Details
The coupling is manufactured from malleable iron conforming to ASTM A197 and uses Class 150 threaded fitting construction.
Fitting dimensions conform to ASME B16.3, with threaded connections manufactured in accordance with ASME B1.20.1.
One end uses a conventional right-hand female thread while the opposite end uses a left-hand female thread. When paired with the proper right-left nipple or pipe ends, rotating the coupling draws both connections together.
Right-Left Design & Typical Applications
Coupling Design
- Opposing internal threads
- Joins stationary piping
- Compact threaded connection
- Class 150 construction
- Requires compatible threads
Typical Applications
- Gas piping systems
- Mechanical piping
- Industrial piping
- Repair applications
- Confined installations
Installation & Selection Considerations
- Confirm the required pipe size.
- Verify both thread directions.
- Use a compatible right-left nipple.
- Use suitable thread sealant.
- Confirm service compatibility.
Right-left connections require the proper opposing thread directions. Willy and the GetPipe.com Team can help confirm pipe size, fitting class, thread orientation, and the compatible right-left nipple for your piping assembly.
Frequently Asked Questions
What is a right and left coupling?
It is a threaded coupling with a right-hand female thread on one end and a left-hand female thread on the opposite end.
What is the purpose of the opposite threads?
The opposing threads allow compatible pipe ends to be drawn together as the coupling is rotated without requiring the surrounding piping to turn.
What material is this coupling made from?
The coupling is manufactured from black malleable iron conforming to ASTM A197.
What pressure class is this fitting?
This right and left coupling is manufactured as a Class 150 threaded malleable iron fitting.
Can I use a standard pipe nipple with this coupling?
A proper right-left connection requires compatible opposing thread directions. A standard nipple with conventional right-hand threads on both ends will not provide the intended right-left connection.
How is this different from a standard coupling?
A standard coupling normally uses conventional right-hand female threads on both ends. This fitting uses right-hand and left-hand threads on opposite ends.
Where are right and left couplings commonly used?
They are useful in gas, mechanical, industrial, repair, and other compatible threaded piping systems where connected pipe cannot easily be rotated.
What should I confirm before ordering?
Confirm pipe size, fitting class, mating thread directions, compatible right-left nipple, and suitability for the intended piping service.
Important Ordering & Installation Notes
- Confirm the required pipe size.
- Verify mating thread directions.
- Use compatible right-left components.
- Apply suitable thread sealant.
- Confirm intended system service.
