{"product_id":"steel-coupling-fnpt","title":"Steel Coupling — Female NPT x Female NPT Pipe Fitting","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBody: carbon steel — high strength and durability for industrial-duty plumbing\u003c\/li\u003e\n\u003cli\u003eConnections: female NPT (FNPT) on both ends\u003c\/li\u003e\n\u003cli\u003eConfigurations: equal (same-size) and reducing (larger-to-smaller) couplings\u003c\/li\u003e\n\u003cli\u003eThread standard: ANSI\/ASME B1.20.1 tapered pipe thread\u003c\/li\u003e\n\u003cli\u003eSize range: 1\/8\" through 2\" NPT port combinations (select Size)\u003c\/li\u003e\n\u003cli\u003eMedia: compressed air, water, oil, fuel, and gas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTypical applications\u003c\/h3\u003e\n\u003cp\u003eUsed 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.
