Built from solid brass, this fitting handles demanding fluid and gas line applications with a rated maximum working pressure of 4,300 psi. The 1\/8 inch thread size makes it well suited for small-bore instrumentation and control tubing runs. It is installed by licensed plumbers, HVAC technicians, and industrial pipefitters wherever a reliable compression-to-female-pipe connection is required.\u003c\/p\u003e\n\u003cp\u003eThis connector is used in residential and commercial HVAC systems, refrigeration lines, pneumatic control circuits, hydraulic instrumentation loops, and general plumbing applications where a compression tube must terminate at a female NPT port. Its compact 1\/8 inch size is common in control-line and sensing-line installations where space is limited and pressure integrity is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and durability in fluid and gas service\u003c\/li\u003e\n  \u003cli\u003eCompression x FNPT end connections allow tool-free tube insertion with a threaded port termination\u003c\/li\u003e\n  \u003cli\u003eMaximum working pressure rated to 4,300 psi for demanding instrumentation and control applications\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch thread size fits standard small-bore NPT female ports\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity suitable for targeted replacement or low-volume service work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement compression connector for small-bore fluid and gas line fittings using 1\/8 inch female NPT threaded ports in HVAC, plumbing, and instrumentation systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified plumber, HVAC technician, or pipefitter in accordance with applicable IPC or IFGC codes. Shut off and depressurize the line completely before removing or installing any compression fitting. Use an appropriate thread sealant on the FNPT threads and ensure the compression ferrule is properly seated before tightening the compression nut. Do not overtighten the compression nut, as over-compression can deform the ferrule and cause leaks.\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\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: FPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 4,300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 66HD-2-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540983185714,"sku":"66HD-2-2","price":17.58,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5f9d6304c17b19119d5f540d9d3c79c.jpg?v=1785866935","url":"https:\/\/voomisupply.com\/products\/parker-66hd-2-2-compression-tube-connector-1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
