The body is molded from acetal copolymer, a rigid engineering plastic that resists moisture, mild chemicals, and wear in fluid-handling systems. The compression end grips the tube mechanically, creating a leak-resistant seal without soldering or flaring. Rated to 150 psi maximum working pressure, this fitting handles moderate-pressure lines in water, pneumatic, and compatible fluid systems. Plumbers, HVAC technicians, and industrial maintenance trades install this type of connector when transitioning from tubing to a threaded pipe port.\u003c\/p\u003e\u003cp\u003eThe 68P-8-4 is suited for light-duty fluid and pneumatic distribution lines in residential and light commercial applications. The acetal copolymer construction makes it appropriate for clean water service and many non-aggressive fluid media. Operating temperature range runs from 0 degrees F minimum to 149 degrees F maximum, keeping it within the service window for most potable water, instrument air, and low-pressure process lines. Install locations typically include equipment panels, filtration assemblies, and instrument tubing runs where a compact straight connector is needed between a tubing line and a threaded port.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCompression x MNPT end connections allow tool-free tube insertion with standard wrench tightening on the NPT side\u003c\/li\u003e\n\u003cli\u003eAcetal copolymer body resists moisture absorption and mild chemical exposure\u003c\/li\u003e\n\u003cli\u003e150 psi maximum working pressure rating for moderate-pressure service\u003c\/li\u003e\n\u003cli\u003eStraight thread size of 11\/16-20 on the compression nut\u003c\/li\u003e\n\u003cli\u003eOperating range from 0 degrees F to 149 degrees F suits most water and instrument-air applications\u003c\/li\u003e\n\u003cli\u003eCompact straight configuration minimizes installation footprint\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style compression fitting for 1\/2-inch OD tubing connecting to 1\/4-inch male NPT threaded ports in light commercial and residential fluid or pneumatic systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed plumber or qualified mechanical technician should install this fitting in accordance with applicable plumbing codes such as the IPC. Shut off and depressurize the supply line before installation. Insert the tubing squarely and fully into the compression end before tightening the nut to avoid uneven seating and potential leaks. Do not over-torque the NPT threads into the mating port; use thread sealant tape or compound rated for the fluid service on the tapered NPT connection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Compression x MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inches NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStraight Thread Size\u003c\/strong\u003e: 11\/16-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: 0 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 149 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Acetal Copolymer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-8-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544448991538,"sku":"68P-8-4","price":35.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57d09f498970800aa7004d1da726bfe4.jpg?v=1785926850","url":"https:\/\/voomisupply.com\/products\/parker-68p-8-4-compression-tube-connector-1-2-in-od-1-4-mnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
