It provides a reliable, leak-resistant mechanical connection in fluid and gas line applications where a compression fitting mates directly to a threaded FNPT port. Built from brass, this connector handles a maximum working pressure of 750 psi and a temperature range of -65 degrees F to 250 degrees F. It is commonly installed by HVAC technicians, plumbers, and industrial pipefitters working on refrigerant, pneumatic, hydraulic, or fluid transfer systems that require a secure tube-to-pipe transition.\u003c\/p\u003e\n\u003cp\u003eThis connector is suited for residential and commercial applications involving copper, brass, or compatible soft tubing running into threaded pipe ports. Typical install scenarios include control line connections, instrument tubing, refrigerant accessory lines, and pneumatic control circuits. The 1\/4-18 NPTF thread standard ensures a dry-seal mechanical fit, reducing reliance on thread sealant compounds. It is sold and packaged individually, making it a practical replacement or maintenance item for field service kits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction for corrosion resistance in fluid and gas service\u003c\/li\u003e\n  \u003cli\u003eCompression x FNPT end connections for tube-to-pipe transitions\u003c\/li\u003e\n  \u003cli\u003e1\/4-18 NPTF thread standard provides a dry-seal mechanical fit\u003c\/li\u003e\n  \u003cli\u003eRated to 750 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -65 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eSold individually — no minimum multi-pack required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement compression tube connector for systems requiring a 1\/4-18 NPTF female threaded port connection with a compression tube inlet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician, plumber, or qualified pipefitter. Before servicing, isolate and depressurize the line and verify the system is de-energized where applicable. Hand-tighten the compression nut onto the tube, then use an appropriate open-end wrench to snug the fitting — do not overtighten, as this can deform the compression ferrule and cause leaks. Verify the NPTF thread engagement and inspect for leaks after restoring line pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Connector\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: 750 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\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: 66CA-8-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542493757746,"sku":"66CA-8-4","price":50.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57f91afcb41be51e92959bea68f39319_18ba126d-fe81-47db-ae06-46a716ff471b.jpg?v=1785901901","url":"https:\/\/voomisupply.com\/products\/parker-66ca-8-4-compression-tube-connector-brass-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
