It features a 1\/4-18 NPTF thread on the female NPT end and accepts standard compression tube fittings on the opposing end. Rated to 200 psi maximum working pressure and a temperature range of -65 to 250 degrees F, this connector suits demanding service environments. Manufactured to SAE J-512 standards, it is installed by licensed plumbers, HVAC technicians, and fluid-system mechanics working on instrumentation, refrigeration, or general hydraulic and pneumatic lines.\u003c\/p\u003e\n\u003cp\u003eThe 66C-8-4 is suited for residential and light commercial applications where a compression tube line must transition to a female NPT port. Typical installation scenarios include refrigeration and air conditioning line sets, pneumatic control tubing, and hydraulic instrumentation connections. The compression end provides a reliable tube-to-fitting seal without soldering, while the NPTF threaded end creates a pressure-tight connection with the mating port.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance and durability in fluid and pneumatic service\u003c\/li\u003e\n  \u003cli\u003e1\/4-18 NPTF thread meets sealing requirements for pressure-tight connections\u003c\/li\u003e\n  \u003cli\u003eCompression x FNPT end configuration allows direct tube-to-port transitions without soldering\u003c\/li\u003e\n  \u003cli\u003eRated to 200 psi maximum working pressure for reliable performance under load\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range of -65 to 250 degrees F covers most field service conditions\u003c\/li\u003e\n  \u003cli\u003eManufactured to SAE J-512 standards for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression tube connector for fluid and pneumatic systems requiring a compression tube to female NPT port transition with a 1\/4-18 thread size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician. Depressurize and isolate the system completely before removing any existing fittings or installing this connector. Apply thread sealant or PTFE tape to the NPTF threads in accordance with applicable plumbing and mechanical codes. Hand-tighten first, then use a wrench to bring the connection to a firm, leak-free seat without over-torquing the brass fitting body.\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: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 200 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: SAE J-512\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 66C-8-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541303755058,"sku":"66C-8-4","price":26.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1737e4e6645110d1c1ca38293c67a88c.jpg?v=1785871818","url":"https:\/\/voomisupply.com\/products\/parker-66c-8-4-compression-tube-connector-1-4-18-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
