Built to handle working pressures up to 400 psi and a temperature range of -65 degrees F to 250 degrees F, this fitting is suited for demanding fluid and pneumatic line applications. Manufactured from brass, it meets D.O.T. FMVSS571.106 and SAE J246 standards, making it appropriate for brake and fuel line systems as well as general hydraulic and pneumatic plumbing. Plumbers, HVAC technicians, and fleet mechanics rely on this type of connector for secure, leak-resistant tube terminations in both mobile and stationary equipment.\u003c\/p\u003e\n\u003cp\u003eThis connector is used in residential, commercial, and mobile equipment installations where a compression tube must transition to a female NPT threaded fitting. Typical applications include compressed air lines, hydraulic systems, brake line assemblies, and fuel system plumbing. The 3\/8-18 NPTF thread size is a common standard in light-duty to medium-duty fluid power and vehicle service work. Its brass construction resists corrosion in environments exposed to water, air, and many petroleum-based fluids.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompression x FNPT end connections for tube-to-pipe transitions\u003c\/li\u003e\n  \u003cli\u003e3\/8-18 NPTF thread size for a pressure-tight seal without secondary sealant\u003c\/li\u003e\n  \u003cli\u003eRated to 400 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -65 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and compatibility with common fluids\u003c\/li\u003e\n  \u003cli\u003eMeets D.O.T.

Depressurize and isolate the line completely before removing or installing any fitting. NPTF threads are designed to seal on the thread form itself, but confirm system requirements before applying thread sealant. Do not overtighten compression fittings, as excess torque can deform the ferrule and compromise the seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Connector\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Compression x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.314 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 400 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -65 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: D.O.T.
