It features a compression end for 5\/16-inch outside diameter tubing and a 1\/4-18 FNPT threaded end, allowing a secure, leak-resistant connection without welding or brazing. Rated to 500 psi maximum working pressure, this fitting handles a temperature range from -30 degrees F to 275 degrees F. It meets ISO 6149 and SAE J1926 standards and is suited for installation by licensed plumbers, HVAC technicians, and hydraulic system mechanics working on instrumentation, refrigeration, or fluid transfer lines.\u003c\/p\u003e\n\u003cp\u003eThis connector is used in residential and light commercial applications where tubing must transition to an FNPT-threaded port on valves, manifolds, gauges, or equipment housings. The brass construction makes it appropriate for use with water, air, oil, and many compatible refrigerants or hydraulic fluids. Its compact single-piece body fits in tight spaces and requires only standard compression fitting tools for installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass body construction for corrosion resistance and durability in fluid systems\u003c\/li\u003e\n  \u003cli\u003eCompression x FNPT end connections for tool-accessible, no-weld installation\u003c\/li\u003e\n  \u003cli\u003eFits 5\/16-inch outside diameter tubing with a 1\/4-18 female NPT thread\u003c\/li\u003e\n  \u003cli\u003eRated to 500 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eMeets ISO 6149 and SAE J1926 standards\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range from -30 degrees F to 275 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression-to-FNPT fitting for fluid and pneumatic systems requiring a 5\/16-inch OD tube connection to a 1\/4-18 female NPT port.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or hydraulic mechanics. Depressurize and drain the system fully before removing or installing any compression fittings. Hand-tighten the compression nut onto the fitting body, then advance with a wrench per standard compression fitting practice — do not overtighten, as brass fittings can deform the ferrule. Verify the system is leak-free under pressure before returning it 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 FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: FPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 500 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -30 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 275 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 6149, SAE J1926\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\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: 66VL-5-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539479953714,"sku":"66VL-5-4","price":28.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21a5dec51830b57541a54424f8527637.jpg?v=1785841206","url":"https:\/\/voomisupply.com\/products\/parker-66vl-5-4-compression-tube-connector-1-4-18","provider":"Voomi Supply","version":"1.0","type":"link"}
