AHFMANG Brass Flare Tube Fittings, 1/4" Male Flare to 1/8" FNPT, 5-Piece
Product description
When a setup needs to join flare tubing to a female NPT connection, matching the fitting ends is essential. This AHFMANG coupling set provides a 1/4" male flare connection and a 1/8" FNPT end. Each fitting is brass, with a 45-degree flare connection. The five-piece set is suited to projects that call for this specific transition across HVAC, hydraulic or pneumatic systems.
Product specs
- Type: Brass flare tube fitting coupling
- Connections: 1/4" male flare x 1/8" female NPT
- Flare connection: 45-degree
- Material and finish: Brass
- Quantity: 5 pieces

The two connection styles make these couplings useful when a tube connection needs to meet a female NPT fitting. The flare end is designed for a flare connection, while the opposite end has female NPT threads. Matching those ends to the parts in your setup helps keep the connection plan straightforward, whether you are assembling a new line or replacing a fitting of the same type.
What it works with


These fittings are identified for use with copper, brass, aluminium or plastic tubing. Their application examples include air conditioning, HVAC, hydraulic and pneumatic systems, where the specified flare-to-NPT transition is needed. This gives you a focused option for connecting compatible tubing to a female NPT port, rather than choosing a coupling with two flare ends or another thread arrangement.

For example, in an HVAC or pneumatic assembly, the 1/4" male flare end can connect to the matching tubing connection while the 1/8" FNPT side joins a compatible male NPT fitting. The two ends serve different roles, so identify the connection type at each point before installation. This is not a potable-water fitting, use it for an appropriate non-potable application.
How to use it
Select the fitting when both connection sizes and types match the parts in your system: 1/4" male flare on the tubing side and 1/8" female NPT on the other. Seat the flare end against its matching flare connection and engage the threaded end with the corresponding NPT fitting. Keep the connections aligned as you assemble them and follow the requirements of the system you are working on. Using the correct end at each junction makes the adapter’s role clear and helps avoid mixing flare and pipe-thread connections.

The set of five is practical for a project that needs several matching adapters, or for keeping the same fitting type available for future work. Compared with sourcing each coupling separately, a multi-piece set keeps identical connection dimensions together for repeat installations. It is also a more targeted choice than a general-purpose connector when the system specifically calls for this flare-to-FNPT combination.


Practical questions
What are the two connection ends? One end is a 1/4" male flare connection and the other is a 1/8" female NPT thread. The flare connection is 45 degrees.

Which tubing materials are listed for use? Copper, brass, aluminium and plastic tubing are listed. Match the tubing connection to the fitting’s flare end.
Can these fittings be used for potable water? No. They are not intended for potable-water use, choose them for a suitable application such as HVAC, hydraulic or pneumatic systems.
Is it worth it?
For a job that calls for a brass 1/4" male flare-to-1/8" FNPT adapter, this five-piece set brings the specified connection combination together in one pack. Its defined ends and listed tubing materials make it a practical fit for compatible HVAC, hydraulic and pneumatic connections, especially when several matching couplings are needed.
