Description
300# Leaded Domestic Brass Threaded Companion Flange
300# Leaded Domestic Brass Threaded Companion Flanges are designed to provide a heavy-duty 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 red brass and domestic, with a 300 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 leaded red brass product with a 300 lb flange pattern and NPT ASTM requirements.
Why Choose a 300# 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
300 lb Flange Pattern
- 300# pressure class
- 300 lb flange pattern
- Domestic leaded red brass construction
- Suitable for compatible higher-duty flange applications
- Manufacturer dimensional and certification documentation available
300# vs. 150# Companion Flange
300# Companion Flange
- 300 lb flange pattern
- Designed for compatible 300# flange systems
- Different flange dimensions and bolt pattern than 150# flanges
- Used where the piping design specifies a 300# flange class
- Must be matched with compatible mating flange components
150# Companion Flange
- 150 lb flange pattern
- Designed for compatible 150# flange systems
- Different dimensions and bolting from a 300# flange
- Not interchangeable solely based on nominal pipe size
- Requires a compatible 150# mating flange
Common Applications
Commercial & Industrial Piping
- Threaded brass piping systems
- Mechanical piping installations
- Industrial utility piping
- Valve connections
- Equipment connections
Serviceable Flange Connections
- Threaded pipe-to-flange transitions
- Bolted equipment connections
- Removable valve connections
- Maintenance access points
- Applications requiring a 300# flange pattern
Installation & Selection Guidance
- Confirm the required nominal flange and pipe size before ordering.
- Verify that a 300# flange pattern is required for the application.
- Do not assume 150# and 300# flange patterns are interchangeable.
- 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 whether leaded red brass is permitted for the intended application.
- Installation should comply with applicable piping codes and project requirements.

What flange pattern does this product use?
The supplied product information identifies it as a 300 lb flange pattern.
Is this flange domestic or import?
The supplied product information identifies this flange as domestic.
What material is this flange made from?
The supplied product information identifies the material as leaded red brass.
Is this flange lead free?
No. The supplied product information specifically identifies this flange as leaded red brass.
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 I use a 300# flange with a 150# mating flange?
