It creates a leak-resistant mechanical joint between a 37-degree flared tube end and a female NPTF port. The connector accepts a 5\/8-inch tube OD on the flare side and a 3\/8-18 NPTF thread on the port side. Rated for up to 5000 psi maximum working pressure, this fitting is suited for demanding fluid transfer applications in industrial, mobile, and stationary equipment. Plumbers, pipefitters, and hydraulic system technicians install this type of fitting where a reliable metal-to-metal flare seal is required at a threaded port connection.\u003c\/p\u003e\u003cp\u003eThis connector is used in hydraulic lines, fuel lines, refrigeration tubing connections, and other pressurized fluid circuits that require a 37-degree JIC-style flare interface terminating at an NPTF port. It is appropriate for both residential and commercial mechanical systems where a permanent or serviceable tube-to-port transition is needed. The NPTF thread provides a dry-seal connection that does not rely on a separate sealant for pressure integrity when properly torqued. This fitting ships in a package quantity of two units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e37-degree flare angle provides a metal-to-metal seal at the tube end\u003c\/li\u003e\n\u003cli\u003e3\/8-18 NPTF thread delivers a dry-seal port connection without requiring thread sealant tape\u003c\/li\u003e\n\u003cli\u003e5000 psi maximum working pressure rating for high-pressure fluid system service\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in hydraulic and fluid power applications\u003c\/li\u003e\n\u003cli\u003eCompact fitting design for use in tight installation spaces\u003c\/li\u003e\n\u003cli\u003eSold in a package quantity of two pieces per order unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for hydraulic and fluid systems requiring a 5\/8-inch tube OD flare x 3\/8-18 NPTF port connector with a 37-degree flare angle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified plumber, pipefitter, or hydraulic technician familiar with flared tube fittings and NPTF thread connections. Depressurize and isolate the fluid circuit completely before removing or installing any fittings. Inspect the tube flare for cracks, ovality, or surface defects before assembly, as a damaged flare face will not seat properly and may leak under pressure. Follow applicable system design codes and the fitting manufacturer guidelines for assembly procedure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 5\/8 inches\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\u003eFlared Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare x NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Working Pressure\u003c\/strong\u003e: 5000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 16381\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541492990258,"sku":"16381","price":125.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a1bfa23f0f5e5d776baaf9f77c4d9d4.jpg?v=1785877760","url":"https:\/\/voomisupply.com\/products\/parker-16381-steel-flared-tube-connector-5-8-in-37-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
