Description
150# Lead-Free Domestic Brass Threaded Companion Flange
150# Lead-Free Domestic Brass Threaded Companion Flanges are designed to provide a bolted flange connection in threaded brass piping systems where lead-free material is required. The threaded bore allows compatible male-threaded pipe to connect directly to the flange, while the companion flange configuration provides a serviceable connection to valves, equipment, and mating flanges.
These flanges are identified as lead-free and domestic, with a 150 lb flange pattern and NPT ASTM requirements noted in the supplied product information. Manufacturer dimensional and certification documentation is provided below.

Threaded Companion Flange Construction
A threaded companion flange incorporates an internally threaded bore that accepts compatible male-threaded pipe. This allows the flange to be installed without welding it directly to the pipe.
Once installed, the flange can be bolted to a compatible mating flange, valve, or equipment connection to create a serviceable piping joint.
The supplied product information identifies this flange as a domestic lead-free brass product with a 150 lb flange pattern and NPT ASTM requirements.
Why Choose a Lead-Free Threaded Companion Flange?
Threaded Pipe Connection
- Threads directly onto compatible male-threaded pipe
- No flange-to-pipe welding required
- Provides a transition from threaded pipe to a bolted flange joint
- Useful near valves and equipment
- Allows the flange joint to be disassembled for future service
Lead-Free Domestic Brass
- Lead-free brass construction
- Domestic product
- 150 lb flange pattern
- Suitable for compatible applications requiring lead-free brass
- Manufacturer dimensional and certification documentation available
Threaded Companion Flange vs. Blind Flange
Threaded Companion Flange
- Includes a threaded center bore
- Connects threaded pipe to a flanged component
- Allows flow through the flange
- Provides a bolted serviceable connection
- Requires compatible NPT threads
Blind Flange
- Solid flange with no center bore
- Used to close a flanged connection
- Stops flow through the flange
- Common for line termination and isolation
- Different function from a threaded companion flange
Common Applications
Commercial & General Piping
- Threaded brass piping systems
- Mechanical piping installations
- Utility piping systems
- Valve connections
- Equipment connections
Serviceable Flange Connections
- Threaded pipe-to-flange transitions
- Bolted equipment connections
- Removable valve connections
- Maintenance access points
- Applications requiring a 150# flange pattern
Installation & Selection Guidance
- Confirm the required nominal flange and pipe size before ordering.
- Verify that a 150# flange pattern is required for the application.
- Verify NPT thread compatibility with the mating pipe.
- Confirm flange dimensions and bolt pattern compatibility with the mating flange or equipment connection.
- Select an appropriate gasket for the mating flange configuration and service conditions.
- Use a thread sealant suitable for the piping material, system media, pressure, and temperature.
- Apply thread sealant according to the sealant manufacturer's instructions.
- Avoid over-tightening threaded brass components.
- Verify pressure, temperature, and media compatibility before installation.
- Confirm that the lead-free material specification meets the requirements of the intended application.
- Installation should comply with applicable piping codes and project requirements.
