One end accepts a compression tube fitting; the other end threads into a standard NPTF male port using a 1\/4-18 thread. Rated to 1000 psi maximum working pressure and capable of handling temperatures from -65 degrees F to 250 degrees F, this connector is suited for hydraulic, pneumatic, refrigeration, and fluid-transfer lines where a reliable, vibration-resistant connection is required. Plumbers, HVAC technicians, and industrial piping contractors are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and light commercial applications wherever a compression-to-MNPT transition is needed. Common install scenarios include instrument tubing connections, control-line plumbing, hydraulic equipment, and HVAC refrigerant or oil-line assemblies that terminate at a threaded male port. The brass construction makes it compatible with water, air, oil, and many common refrigerants at moderate pressures. It ships as a single piece, making it easy to order exact quantities for service calls or small-scale jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompression x MNPT end connections — no soldering or flaring required on the tube side\u003c\/li\u003e\n  \u003cli\u003e1\/4-18 NPTF thread standard for a pressure-tight threaded seal\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch tube outside diameter compression connection\u003c\/li\u003e\n  \u003cli\u003e1000 psi maximum working pressure for demanding fluid and pneumatic service\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -65 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance in water, air, and oil service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for systems that require a 3\/8 inch OD tube compression connection transitioning to a 1\/4-18 NPTF male threaded port.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or qualified industrial pipefitters. Depressurize and isolate the line completely before disassembling any existing fittings. Hand-tighten the NPTF thread first, then use a wrench for final make-up — avoid overtightening, which can crack brass fittings or distort the compression ferrule. Follow applicable codes such as ASME B31.1 or local mechanical codes for pressure-rated tubing assemblies.\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: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1000 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: 68CA-6-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540364722482,"sku":"68CA-6-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5793300430df96b81399d0c458091b3.jpg?v=1785853443","url":"https:\/\/voomisupply.com\/products\/parker-68ca-6-4-compression-tube-connector-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
