It transitions between a compression-style tube end and an MNPT fitting, creating a secure, leak-resistant connection in fluid and pneumatic lines. With a maximum working pressure of 2850 psi and an operating temperature range of -65 degrees F to 250 degrees F, this connector is built for demanding service conditions. The all-brass construction resists corrosion and holds up in both liquid and low-pressure gas applications. Plumbers, HVAC technicians, and fluid power mechanics install this type of fitting during system assembly or repair work.\u003c\/p\u003e\n\u003cp\u003eThis compression connector is suited for residential and light commercial installations where 3\/16-inch OD tubing meets a threaded port on a valve, manifold, instrument, or equipment body. Common applications include refrigeration lines, instrument tubing, hydraulic control circuits, and fuel or pneumatic systems that require a reliable tube-to-pipe transition. The Compression x MNPT end configuration makes it compatible with standard NPT-threaded ports following MPT thread standards.\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 MNPT end connections for tube-to-pipe transitions\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch tube outside diameter compatibility\u003c\/li\u003e\n  \u003cli\u003eRated to 2850 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eOperating range of -65 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 1.14 inches for tight installation spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for systems using 3\/16-inch OD compression tubing with standard male NPT threaded ports following MPT thread standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or fluid power mechanics. Depressurize and isolate the system completely before removing or installing any compression fitting. Hand-tighten the compression nut onto the fitting body, then advance with a wrench per standard compression fitting practice — avoid overtightening, which can deform the ferrule and compromise the seal. Verify thread compatibility with the receiving port before installation; NPT and BSP threads are not interchangeable.\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 Standard\u003c\/strong\u003e: MPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 2850 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -65 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 68HD-3-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539037520178,"sku":"68HD-3-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f79b15106191a21143dc50f0d54a26b1.jpg?v=1785833450","url":"https:\/\/voomisupply.com\/products\/parker-68hd-3-2-compression-tube-connector-3-16-od-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
