Description
125# Lead Free Brass Union
125# Lead Free Brass Unions are threaded fittings designed to join two compatible piping sections while providing a serviceable connection that can be separated without cutting or rotating the adjoining pipe. The union configuration makes these fittings especially useful near valves, pumps, fixtures, and equipment that may require future maintenance or replacement.
These fittings conform with the lead-content requirements for lead-free plumbing as defined by the U.S. Safe Drinking Water Act and are certified to contain ≤0.25 weighted average % lead. Manufacturer dimensional, certification, and material safety documentation is provided below.

Union Construction
A threaded union creates an in-line piping connection that can be separated at the union joint without requiring the connected pipe sections to be rotated.
This makes a union especially useful where valves, pumps, fixtures, meters, equipment, or sections of piping may need to be removed for maintenance, inspection, or replacement.
Lead free brass construction makes this fitting suitable for applications requiring compliance with applicable lead-content requirements for plumbing products.

The fittings are also identified as being certified to contain ≤0.25 weighted average % lead. Review the manufacturer certification letter in the Product Documents section for additional certification information.
Union vs. Coupling
Union
- Provides a serviceable in-line connection
- Can be separated without rotating adjoining piping
- Useful near valves and equipment requiring maintenance
- Designed for future disassembly
- More serviceable than a standard coupling
Coupling
- Joins two compatible male-threaded piping components
- Creates a straightforward in-line connection
- Does not include a separable union joint
- Commonly used for extending pipe runs
- Different service function from a union
Common Applications
Plumbing & Water Systems
- Potable-water piping where applicable
- Commercial plumbing systems
- Water distribution piping
- Fixture connections
- Serviceable threaded piping assemblies
Commercial & General Service
- Mechanical piping installations
- Utility piping systems
- Valve connections
- Pump connections
- Equipment requiring periodic removal or maintenance
Installation & Selection Guidance
- Confirm the required nominal union size before ordering.
- Verify thread compatibility with both mating piping components.
- Use an appropriate thread sealant suitable for the piping material, system media, pressure, and temperature.
- Apply thread sealant according to the sealant manufacturer's instructions.
- Install the union where sufficient access is available for future disassembly.
- Align both piping sections properly before tightening the union connection.
- Avoid over-tightening threaded brass fittings.
- Confirm that the 125# fitting class is suitable for the intended piping system.
- Verify media, pressure, and temperature compatibility before installation.
- Confirm lead-free requirements for the specific plumbing application.
- Inspect the completed connections for leaks before placing the system into service.
- Installation should comply with applicable plumbing codes and project requirements.

Frequently Asked Questions
What is a brass union used for?
A brass union is used to join two threaded piping sections while providing a connection that can be separated later for maintenance, inspection, or equipment replacement.
How is a union different from a coupling?
A union includes a separable joint that allows the piping connection to be taken apart without rotating the adjoining pipe. A standard coupling does not provide the same serviceable union joint.
What pressure class is this fitting?
This fitting is identified as a 125# lead free brass union.
Is this fitting lead free?
Yes. The supplied product information states that it conforms with lead-content requirements for lead-free plumbing as defined by the U.S. Safe Drinking Water Act.
What is the certified lead content?
The fitting is identified as containing no more than 0.25 weighted average percent lead.
Why use a union near a valve or pump?
A union provides a convenient disconnection point, allowing a valve, pump, or other component to be removed without cutting the piping or rotating long sections of connected pipe.
Can the union be disconnected after installation?
Yes. The union is specifically designed to provide a removable connection for future servicing or system access.
Can this fitting be used in potable-water systems?
The supplied product information states that the fitting conforms with U.S. Safe Drinking Water Act lead-content requirements for lead-free plumbing. Confirm all applicable local plumbing-code and system requirements before installation.
Where can I find fitting dimensions?
