Description
150# Leaded Domestic Brass Threaded Companion Flange
150# Leaded Domestic Brass Threaded Companion Flanges are designed to provide a bolted flange connection in threaded brass piping systems. 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 leaded and domestic, with 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 leaded brass fitting with NPT ASTM requirements.
Why Choose a Threaded Companion Flange?
Threaded Pipe Connection
- Threads directly onto compatible male-threaded pipe
- No flange-to-pipe welding required
- Provides a convenient transition from threaded pipe to a bolted flange joint
- Useful near valves and equipment
- Allows the bolted flange connection to be disassembled later
Domestic Brass Construction
- Domestic product
- Leaded brass construction
- Suitable for compatible industrial and commercial piping applications
- Manufacturer certification documentation available
- Dimensional reference provided for product selection
Threaded Companion Flange vs. Welded Flange
Threaded Companion Flange
- Installs onto compatible threaded pipe
- Does not require welding to the pipe
- Provides a bolted flange connection
- Useful where a threaded-to-flanged transition is required
- Requires compatible NPT threads
Welded Flange
- Attached to pipe by welding
- Requires appropriate welding procedures
- Common in permanent welded piping systems
- Different installation method from a threaded companion flange
- Does not rely on pipe threads for flange attachment
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 where flange welding is not preferred
Installation & Selection Guidance
- Confirm the required nominal flange and pipe size before ordering.
- Verify NPT thread compatibility with the mating pipe.
- Use a thread sealant suitable for the piping material, system media, pressure, and temperature.
- Apply thread sealant according to the sealant manufacturer's instructions.
- Confirm the flange bolt pattern and dimensions match the mating flange or equipment connection.
- Select an appropriate gasket for the mating flange configuration and application.
- Avoid over-tightening threaded brass components.
- Verify pressure, temperature, and media compatibility before installation.
- Confirm whether leaded brass is permitted for the intended application.
- Installation should comply with applicable piping codes and project requirements.
Important Material Notice
- This product is identified as leaded brass.
- Confirm that leaded brass is permitted for the intended application before installation.
- Do not assume this product meets lead-free potable-water requirements.
- Review the manufacturer certification documentation for applicable material and compliance information.

Frequently Asked Questions
What is a threaded companion flange?
A threaded companion flange has an internally threaded bore that connects to compatible male-threaded pipe and provides a bolted flange connection to another flange, valve, or equipment connection.
What pressure class is this flange?
This flange is identified as a 150# threaded companion flange.
Is this flange domestic?
Yes. The supplied product information identifies this flange as domestic.
Is this flange lead free?
No. The supplied product information specifically identifies this flange as leaded.
What thread type does this flange use?
The supplied product information identifies the threaded connection as NPT.
Does this flange need to be welded to the pipe?
No. The flange is designed to connect to compatible threaded pipe rather than being welded directly to the pipe.
Can the flange connection be disassembled later?
Yes. The bolted flange joint can be disassembled for maintenance or equipment access, subject to the piping system design.
Can this flange be used for potable water?
The product is identified as leaded brass. Confirm all applicable regulatory, plumbing-code, and project requirements before using it in any water system.
