It provides a secure, leak-resistant connection between soft or semi-rigid tubing and a male NPT fitting without requiring soldering or flaring. The connector is rated for a maximum working pressure of 150 psi and handles temperatures from 0 degrees F to 150 degrees F, making it suitable for low-pressure fluid and pneumatic lines in HVAC, plumbing, and refrigeration applications. Licensed trades and experienced technicians install this fitting where a compression-to-threaded transition is required.\u003c\/p\u003e\n\u003cp\u003eThis connector is used in residential and light commercial applications where 1\/4-inch OD tubing must terminate at a male NPT threaded port. Common install scenarios include refrigerant sensing lines, instrument tubing, and low-pressure fluid transfer lines. The NPTF thread standard ensures a pressure-tight seal at the threaded connection. The compression end grips the tubing mechanically, eliminating the need for solder or adhesive. This fitting is well suited for copper, brass, or compatible soft-metal tubing in confined service areas.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction for corrosion resistance in fluid and pneumatic service\u003c\/li\u003e\n  \u003cli\u003eCompression x MNPT end connections for tool-free tubing attachment on the compression end\u003c\/li\u003e\n  \u003cli\u003e1\/4-18 NPTF thread standard provides a pressure-tight threaded seal\u003c\/li\u003e\n  \u003cli\u003eRated to 150 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eTemperature range of 0 degrees F to 150 degrees F\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch OD tube fitting for common small-diameter tubing used in HVAC and refrigeration lines\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 1\/4-inch OD tubing with 1\/4-18 NPTF male threaded ports in low-pressure fluid or pneumatic service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber, HVAC technician, or refrigeration mechanic. Shut off and depressurize the system fully before removing or installing compression fittings. Hand-tighten the compression nut onto the tubing, then advance with a wrench per standard compression fitting practice — do not overtighten, as brass fittings can crack. Ensure the tubing end is cut cleanly and deburred before inserting into the compression seat to achieve a proper seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\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\u003eThread Size\u003c\/strong\u003e: 1\/4-18\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: 1\/4 inch\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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\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-4-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542374613298,"sku":"68P-4-4","price":34.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff7c14d6d617791000c758b70ad50c05.jpg?v=1785898925","url":"https:\/\/voomisupply.com\/products\/parker-68p-4-4-compression-tube-connector-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
