Brass Poly-Flo x Female NPT Adapter\u003c\/strong\u003e is a brass Poly-Flo adapter that creates a leak-tight tube connection without flaring the tube end. A ferrule or cutting ring bites into the tube OD as the nut is tightened — forming a metal-to-metal seal rated for high pressure without any tube preparation beyond a clean, square cut. Flareless fittings are the standard in hydraulic instrumentation lines, high-pressure control systems, and OEM equipment where tube flaring is impractical.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eBrass (dezincification-resistant)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eConnection Type\u003c\/td\u003e\n\u003ctd\u003eFlareless (ferrule\/bite-type or Poly-Flo)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eShape\u003c\/td\u003e\n\u003ctd\u003eAdapter\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eEnd Connections\u003c\/td\u003e\n\u003ctd\u003eSee product title\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eInstrument tubing, hydraulic, fuel lines\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eNo tube flaring required — cut tube square and assemble\u003c\/li\u003e\n  \u003cli\u003eFerrule or cutting ring creates metal-to-metal seal rated for high-pressure service\u003c\/li\u003e\n  \u003cli\u003eBrass construction compatible with copper, brass, and compatible aluminum tubing\u003c\/li\u003e\n  \u003cli\u003eResists vibration loosening better than soft-ferrule compression fittings on rigid tubing\u003c\/li\u003e\n  \u003cli\u003eStandard in hydraulic instrumentation, fuel systems, and OEM control equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCommon Applications\u003c\/h2\u003e\n\u003cp\u003eHydraulic instrumentation and gauge lines, fuel injection system tubing, high-pressure instrument air, OEM control panel plumbing, and any high-pressure tubing connection on rigid steel or copper tube where flaring tools are not available.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Resources\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/pages\/flare-fittings-sae-45-vs-inverted\"\u003eSAE 45° vs. Inverted Flare vs. Flareless — Identification Guide\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/pages\/compression-fitting-sizing-chart\"\u003eTube OD Sizing Reference\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/pages\/brass-fitting-types-and-sizes-guide\"\u003eBrass Fitting Types and Sizes Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCross-References\u003c\/h2\u003e\u003cp\u003eThis part is an equivalent for industry part numbers \u003cstrong\u003e02666-0502\u003c\/strong\u003e, \u003cstrong\u003e1266x5\u003c\/strong\u003e, \u003cstrong\u003e266P0502\u003c\/strong\u003e, \u003cstrong\u003e266-P-05x02\u003c\/strong\u003e, \u003cstrong\u003e266P-5-2\u003c\/strong\u003e, \u003cstrong\u003e266PF-5A\u003c\/strong\u003e, \u003cstrong\u003e5053K39\u003c\/strong\u003e, \u003cstrong\u003e66P-5-2\u003c\/strong\u003e, \u003cstrong\u003e66PF-5-2\u003c\/strong\u003e, \u003cstrong\u003e9566-52\u003c\/strong\u003e, \u003cstrong\u003eAP66-P-5X2\u003c\/strong\u003e, \u003cstrong\u003eF266-5-2\u003c\/strong\u003e, \u003cstrong\u003eMP66-52\u003c\/strong\u003e, \u003cstrong\u003ePG66D\u003c\/strong\u003e.
