Description
125# Lead Free Brass Coupling
125# Lead Free Brass Couplings are threaded fittings designed to join two compatible male-threaded pipe sections in a straight run. The full coupling configuration provides female threaded connections on both ends, making it a practical choice for extending pipe, joining nipples, or connecting threaded piping components.
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.

Coupling Construction
A threaded coupling is a straight fitting with female threads on both ends. It is designed to connect two compatible male-threaded pipes, nipples, or fittings along the same centerline.
The coupling configuration is commonly used to extend threaded pipe runs, repair or modify existing piping, or connect adjacent threaded components without changing pipe direction.
Lead free brass construction makes this fitting suitable for applications requiring compliance with applicable lead-content requirements for plumbing products.

Coupling vs. Reducing Coupling
Standard Coupling
- Joins matching nominal pipe sizes
- Female threaded connection on both ends
- Maintains the same pipe size through the fitting
- Used for straight pipe extensions
- Does not provide an integral size reduction
Reducing Coupling
- Connects two different nominal pipe sizes
- Provides a straight in-line size transition
- Combines coupling and reducing functions
- Useful where pipe size changes within a straight run
- Different application from a standard coupling
Common Applications
Plumbing & Water Systems
- Potable-water piping where applicable
- Commercial plumbing systems
- Water distribution piping
- Pipe extensions
- General threaded brass piping assemblies
Commercial & General Service
- Mechanical piping installations
- Utility piping systems
- Equipment connections
- Nipple-to-nipple connections
- Straight threaded piping repairs and modifications
Installation & Selection Guidance
- Confirm the required nominal fitting size before ordering.
- Verify compatibility with both mating male-threaded 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.
- Start both threaded connections carefully to avoid cross-threading.
- 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 both completed threaded connections for leaks before placing the system into service.
- Installation should comply with applicable plumbing codes and project requirements.
