The Steel Coupling joins two female-threaded pipes or components in a single inline fitting — either connecting two pipes of the same size or stepping one size down to another without a chain of adapters. Built from carbon steel with female NPT (FNPT) threads on both ends, it delivers a strong, leak-tight connection for compressed-air, water, oil, fuel, and gas lines in demanding shop and industrial systems.
Key specifications
- Body: carbon steel — high strength and durability for industrial-duty plumbing
- Connections: female NPT (FNPT) on both ends
- Configurations: equal (same-size) and reducing (larger-to-smaller) couplings
- Thread standard: ANSI/ASME B1.20.1 tapered pipe thread
- Size range: 1/8" through 2" NPT port combinations (select Size)
- Media: compressed air, water, oil, fuel, and gas
Typical applications
Used throughout air-compressor plumbing, pneumatic tools, water and fuel lines, and general industrial fluid systems to join pipe and fittings — whether extending a run of the same pipe size or transitioning between two sizes. A common choice for connecting nipples, manifolds, drops, regulators, and hose assemblies in compressed-air distribution.
This carbon-steel FNPT x FNPT coupling provides a rugged, leak-free connection for compressed-air and fluid-handling systems, pairing the strength of steel with standard NPT threading for a reliable, lasting fit.
