It features a 37-degree flare end on one side and a 3\/8-18 NPTF male thread on the other, providing a leak-resistant metal-to-metal seal at both connections. Rated for a maximum static working pressure of 6000 psi and a maximum dynamic working pressure of 3300 psi, this fitting is built for demanding service environments. The brass construction offers good corrosion resistance and machinability. Licensed HVAC technicians, plumbers, and hydraulic system technicians install this type of adapter when transitioning between flared tubing and NPT-threaded ports on valves, manifolds, or equipment housings.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for use in hydraulic lines, refrigeration and fluid transfer systems, and industrial plumbing applications where a 3\/8-inch OD flared tube must connect to a 3\/8-18 NPTF male port. The Flare x NPTF end configuration makes it a common choice when connecting copper or steel tubing to threaded equipment fittings. It complies with ISO 8434-2, SAE 070102, and SAE J514 standards, confirming dimensional and performance consistency across applications. Sold in a package quantity of five.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e37-degree flare end meets SAE J514 and ISO 8434-2 dimensional standards\u003c\/li\u003e\n  \u003cli\u003e3\/8-18 NPTF thread provides a dry-seal connection without requiring sealant tape on conforming ports\u003c\/li\u003e\n  \u003cli\u003e6000 psi maximum static working pressure for high-pressure system service\u003c\/li\u003e\n  \u003cli\u003e3300 psi maximum dynamic working pressure rating\u003c\/li\u003e\n  \u003cli\u003eBrass construction resists corrosion in fluid and refrigeration service\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1.43 inches for compact installation in tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flare-to-NPTF adapter for systems using 3\/8-inch OD flared tubing and 3\/8-18 NPTF threaded ports, conforming to ISO 8434-2, SAE 070102, and SAE J514 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician familiar with flared tube fitting assembly and NPT thread engagement. Depressurize and isolate the system fully before removing or installing any fittings. NPTF threads are designed to seal on the threads themselves; inspect threads for damage before assembly and do not over-torque, which can crack brass fittings. Verify the mating flare nut and tube are properly formed to 37 degrees before tightening to avoid leaks at the flare seat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Male Adapter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare x NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Static Working Pressure\u003c\/strong\u003e: 6000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Dynamic Working Pressure\u003c\/strong\u003e: 3300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.43 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 8434-2, SAE 070102, SAE J514\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PT-00259\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538972803378,"sku":"PT-00259","price":53.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51a6731bb056c20c7e9e862587939412.jpg?v=1785831432","url":"https:\/\/voomisupply.com\/products\/parker-pt-00259-brass-male-adapter-3-8in-37-degree-flare-nptf","provider":"Voomi Supply","version":"1.0","type":"link"}
