It features a 3\/8-18 NPTF thread on the male pipe end and a compression-style connection on the tube end, allowing a secure, leak-resistant seal without welding or flaring. Rated to 1400 psi maximum working pressure and suitable for temperatures ranging from -65 degrees F to 250 degrees F, this fitting handles demanding service conditions. It is installed by licensed plumbers, HVAC technicians, and industrial pipefitters working on compressed air, hydraulic, or process fluid lines.\u003c\/p\u003e\n\u003cp\u003eThis connector is suited for residential and light commercial applications where tubing must terminate into a threaded port on valves, manifolds, pumps, or equipment panels. The compression-to-MNPT configuration is common in HVAC refrigerant-adjacent plumbing, compressed air distribution, fuel lines, and instrumentation tubing runs. Its all-brass construction resists corrosion and is compatible with a wide range of media including water, oil, and many industrial gases.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance and durability across a wide range of media\u003c\/li\u003e\n  \u003cli\u003eCompression x MNPT end connections for tool-friendly, no-flare installation\u003c\/li\u003e\n  \u003cli\u003e3\/8-18 NPTF thread standard ensures pressure-tight engagement with matching female ports\u003c\/li\u003e\n  \u003cli\u003e1400 psi maximum working pressure rating suits high-demand fluid and pneumatic circuits\u003c\/li\u003e\n  \u003cli\u003eWide temperature range of -65 degrees F to 250 degrees F supports diverse service environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation compression connector for systems requiring a 3\/8-18 NPTF male pipe thread port with a compression tube inlet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or pipefitters. Depressurize and isolate the line completely before disassembly or fitting installation. Hand-tighten the compression nut onto the tube, then advance with a wrench to achieve a proper compression seal without over-tightening, which can deform the ferrule. Follow applicable IPC and IFGC code requirements for the specific media and service environment.\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 MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-18 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: 1400 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: 68CA-4-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540183417138,"sku":"68CA-4-6","price":18.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b434bc7ec03b51e29a345db5aef54cc_1823f177-16d2-4590-bb30-575a8079c990.jpg?v=1785848296","url":"https:\/\/voomisupply.com\/products\/parker-68ca-4-6-compression-tube-connector-3-8-18","provider":"Voomi Supply","version":"1.0","type":"link"}
