Description
Right Left Black Nipples Sch40
ASC / SCI Schedule 40 Right Left Black Nipples are welded carbon steel pipe nipples designed with a right-hand thread on one end and a left-hand thread on the opposite end.
This opposite-thread configuration allows compatible piping components to be drawn together as the nipple is turned. Right-left nipples are commonly used in gas piping and other threaded piping assemblies where a union cannot or should not be used.

Construction Details
These right-left nipples are manufactured from ASTM A53 welded steel pipe with Schedule 40 wall construction and a black finish.
Finished welded steel nipples conform to ASTM A733. Pipe threads are manufactured in accordance with ASME B1.20.1.
Unlike a conventional nipple with matching thread directions, the right-left design uses opposite thread directions on the two ends so compatible fittings can be drawn together by rotating the nipple.
Right-Left Design & Typical Applications
Right-Left Design
- Opposite thread directions
- Threaded on both ends
- Schedule 40 steel pipe
- Compact connection method
- Designed for matching fittings
Typical Applications
- Gas piping systems
- Mechanical piping
- Industrial piping
- Threaded steel assemblies
- Union-restricted installations
Installation & Selection Considerations
- Confirm the required pipe size.
- Verify the required nipple length.
- Use matching right-left fittings.
- Use compatible thread sealant.
- Confirm service compatibility.
Right-left nipple installations require the correct opposing thread configuration. Willy and the GetPipe.com Team can help confirm pipe size, nipple length, Schedule 40 requirements, and compatible right-left fittings for your piping system.
Frequently Asked Questions
What is a right-left pipe nipple?
A right-left nipple has a right-hand thread on one end and a left-hand thread on the opposite end.
What is the ASC figure for these nipples?
The black Schedule 40 right-left nipple is ASC / SCI Figure 83RL4.
What material are these nipples made from?
They are manufactured from welded carbon steel pipe conforming to ASTM A53.
What schedule are these pipe nipples?

What standards apply to the nipples and threads?
The welded steel nipples conform to ASTM A733, with pipe threads manufactured in accordance with ASME B1.20.1.
Why use a right-left nipple?
The opposite thread directions allow compatible threaded components to be drawn together as the nipple is rotated.
Where are right-left nipples commonly used?
They are commonly used in gas piping and other threaded piping applications where the piping arrangement calls for a right-left connection instead of a union.
What should I confirm before ordering?
Confirm pipe size, nipple length, Schedule 40 requirements, thread orientation, and that the mating fittings have the proper right-left thread configuration.
Important Ordering & Installation Notes
- Confirm the required pipe size.
- Verify the required nipple length.
