It features a 3\/8-18 NPTF thread and a compression-by-MNPT end connection configuration. With a maximum working pressure of 400 psi and a rated temperature range of -65 to 250 degrees F, this fitting is built for demanding service conditions. It meets D.O.T. FMVSS571.106 and SAE J246 standards, making it appropriate for regulated mobile and hydraulic brake line applications. Licensed plumbers, HVAC technicians, and fleet maintenance technicians install this fitting in both stationary and mobile equipment contexts.\u003c\/p\u003e\n\u003cp\u003eThis connector is used in hydraulic, pneumatic, and fluid transfer lines where a compression tube end must transition to a threaded male NPT port. Typical applications include brake line assemblies, fuel system plumbing, and air line installations on commercial vehicles and industrial equipment. The 0.408-inch inside diameter accommodates standard tubing sizes for these system types. It is equally suited to shop-fabricated assemblies and field repair work where a reliable, pressure-rated compression fitting is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompression x MNPT end connections for tube-to-pipe-thread transitions\u003c\/li\u003e\n  \u003cli\u003e3\/8-18 NPTF thread for leak-resistant dryseal engagement\u003c\/li\u003e\n  \u003cli\u003e400 psi maximum working pressure for hydraulic and pneumatic service\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -65 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and machinability\u003c\/li\u003e\n  \u003cli\u003eMeets D.O.T.

Shut off and fully depressurize the system before removing or installing any fittings. Hand-tighten the NPTF thread first, then apply wrench turns per standard dryseal thread practice — do not overtighten, as brass threads can be damaged. Verify all connections are leak-free before returning the system to service.\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 MNPT\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: 0.408 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.
