Brass Equal Coupling — Female x Female NPT
The Brass Equal Coupling is a solid brass straight fitting with female NPT (FNPT) threads on both ends, used to join two same-size pipes or nipples in a straight line. With matching connections on each end, it cleanly extends a run or links two male-threaded fittings, making it one of the most common building blocks in any compressed-air or pipe assembly.
Key specifications
- Material: solid brass — corrosion-resistant and durable
- Thread: female NPT (FNPT) tapered threads on both ends
- Configuration: equal (straight) coupling — same size both ends
- Available sizes: 1/8", 1/4", 3/8", 1/2", 3/4", and 1" FNPT
- Connection: joins two male-threaded pipes, nipples, or fittings
Typical applications
Ideal for compressed-air lines, air tools, and shop plumbing, as well as water, fuel, natural gas, and low-pressure hydraulic systems. The soft, ductile brass forms a tight, leak-resistant seal and installs easily with standard pipe wrenches and thread sealant.
Whether you are extending an air line or tying two nipples together, this solid brass equal coupling delivers a strong, corrosion-resistant joint in a compact FNPT x FNPT package, available in sizes from 1/8" through 1".
