It features a compression inlet on one end and a 1\/4-18 NPTF female thread on the other, providing a leak-resistant mechanical connection without the need for soldering or flaring. Rated to 1900 psi maximum working pressure, this fitting handles demanding service conditions. The brass construction offers good corrosion resistance across a wide temperature range, from -65 degrees F to 250 degrees F. Plumbers, HVAC technicians, and instrumentation mechanics install this fitting in refrigeration, hydraulic, and fluid-transfer lines.\u003c\/p\u003e\n\u003cp\u003eThis connector is suited for residential and light commercial applications where tubing must terminate at a threaded port on valves, manifolds, or equipment housings. It is commonly used in HVAC refrigerant line sets, compressed air systems, hydraulic circuits, and instrumentation tubing where a reliable compression-to-female-NPT transition is required. The NPTF thread standard ensures a pressure-tight seal when properly torqued into a compatible female port.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-18 NPTF female thread for a pressure-tight connection at the port end\u003c\/li\u003e\n  \u003cli\u003eCompression inlet allows tubing connection without soldering or flaring\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003e1900 psi maximum working pressure for demanding fluid and pneumatic service\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -65 degrees F to 250 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression fitting for use with tubing and female NPT-threaded ports in fluid power, HVAC, and instrumentation systems where a compression-to-FNPT transition connector is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers, HVAC technicians, or pipefitters following applicable IPC and system-specific codes. Shut off and depressurize the line before disassembly or installation. Hand-tighten the compression nut onto the tubing, then wrench-tighten according to standard compression fitting practice; do not overtighten, as this can damage the ferrule and tubing. Apply an appropriate thread sealant to the NPTF threads as required by the system fluid and local code.\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 inches\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: 1900 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\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: 66CA-3-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539576717618,"sku":"66CA-3-4","price":37.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbb89a3e8801046dfc41968306540bf1.jpg?v=1785843360","url":"https:\/\/voomisupply.com\/products\/parker-66ca-3-4-compression-tube-connector-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
