It uses a compression fitting on one end and a 1\/4-18 NPTF male threaded connection on the other, providing a reliable, leak-resistant joint without soldering or flaring. Rated to 150 psi maximum working pressure and suitable for temperatures from 0 degrees F to 150 degrees F, this connector suits refrigeration, pneumatic, and fluid-transfer lines common in HVAC and plumbing service work. Licensed technicians and journeyman plumbers are the typical installers for this type of fitting.\u003c\/p\u003e\n\u003cp\u003eThis connector is used in residential and light commercial applications where tubing must transition to a threaded pipe port. Common scenarios include connecting copper or compatible polymer tubing to valve bodies, manifolds, or equipment ports with NPT-threaded inlets. The compression end allows installation without open flame, making it appropriate for retrofits and service calls in occupied spaces where torch work is restricted or impractical. The brass construction resists corrosion in air, water, and many refrigerant-compatible fluid systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance in air, water, and compatible fluid systems\u003c\/li\u003e\n  \u003cli\u003eCompression x MNPT end connections allow flame-free installation on 5\/16-inch OD tubing\u003c\/li\u003e\n  \u003cli\u003e1\/4-18 NPTF thread standard ensures a pressure-tight, mechanically engaged connection\u003c\/li\u003e\n  \u003cli\u003eRated to 150 psi maximum working pressure for reliable service in low- to medium-pressure lines\u003c\/li\u003e\n  \u003cli\u003eOperating range of 0 degrees F to 150 degrees F covers most residential and light commercial service conditions\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 5\/16-inch outside diameter tubing and equipment or valve bodies with a 1\/4-18 NPTF male NPT threaded port.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or HVAC technicians following applicable IPC or IFGC guidelines for the service fluid involved. Shut off and depressurize the line before disassembly or fitting installation. Hand-tighten the compression nut, then advance with a wrench only to the degree needed to seat the ferrule without over-compression, which can crack the ferrule or deform the tubing. Verify the connection is leak-free under system pressure before returning the system to service.\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: 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\u003eTube Outside Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 150 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: 0 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: 68P-5-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541970911538,"sku":"68P-5-4","price":17.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/179f365008700f0cbd5475eb91078667.jpg?v=1785888667","url":"https:\/\/voomisupply.com\/products\/parker-68p-5-4-compression-tube-connector-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
