"This 1-1/2"" x 1-1/4"" black steel reducing coupling joins two different pipe sizes, connecting 1-1/2"" x 1-1/4"" threaded black pipe on a gas, steam, or black-iron run. Standard tapered (NPT) threads make a strong, pressure-tight transition between sizes.
Key Features:
- Reduces Between Sizes -- Connects 1-1/2"" x 1-1/4"" threaded black pipe ends of different sizes.
- Black Steel -- Carbon steel for gas, steam, and black-iron service (non-potable).
- NPT Threads -- Standard tapered threads for a pressure-tight joint.
- Size Transition -- Steps a run down to the next pipe size in one fitting.
- Durable -- Strong threaded connection for demanding service.
Where to Use:
- Building maintenance -- Joining threaded black-iron runs for gas and steam service
- Rough plumbing -- Connecting threaded pipe on new gas, steam, and black-iron runs
- Code compliance -- Black steel couplings for approved gas and steam connections
