It uses Parker's Vibra-Lok compression style, which provides a secure, vibration-resistant bite-style grip on the tube without the need for flaring or soldering. The connector is rated to a maximum working pressure of 600 psi and is suitable for service across a temperature range of -30 degrees F to 275 degrees F. It is installed by licensed plumbers, HVAC technicians, and pipefitters working on hydraulic, pneumatic, refrigeration, or fluid transfer lines where a reliable tube-to-thread transition is required.\u003c\/p\u003e\n\u003cp\u003eThe 68VL-4-4 is suited for residential and light commercial applications involving tubing connections to threaded ports on valves, manifolds, and instrumentation. The Compression x MNPT end configuration allows direct connection from soft copper, aluminum, or plastic tubing on one end to a 1\/4-18 male NPT threaded fitting or port on the other. It is a single-piece connector appropriate for tight-space installations where a straight inline fitting is needed. It meets ISO 6149 and SAE J1926 standards, making it appropriate for use in systems that require compliance with those specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVibra-Lok compression style — no flaring or soldering required for tube end\u003c\/li\u003e\n  \u003cli\u003eRated to 600 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance in fluid and pneumatic service\u003c\/li\u003e\n  \u003cli\u003e1\/4-18 thread size with MPT thread standard for direct port connection\u003c\/li\u003e\n  \u003cli\u003eMeets ISO 6149 and SAE J1926 standards\u003c\/li\u003e\n  \u003cli\u003eOperating range of -30 degrees F to 275 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression tube connector for use in fluid, pneumatic, and instrumentation systems requiring a Compression x MNPT straight inline fitting with a 1\/4-18 MPT thread size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber, HVAC technician, or pipefitter. De-pressurize and isolate the system completely before disconnecting or installing any fitting. Ensure tubing is cut squarely and deburred before inserting into the compression end to achieve a proper seal. Hand-tighten first, then use a wrench to complete the connection — do not overtighten, as brass fittings can crack or distort under excessive torque.\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: MPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompression Style\u003c\/strong\u003e: Vibra-Lok\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 600 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -30 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 275 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 6149, SAE J1926\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: 68VL-4-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539189104946,"sku":"68VL-4-4","price":23.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2a4731be41f736ae41bfb7d0e2d6f41.jpg?v=1785836250","url":"https:\/\/voomisupply.com\/products\/parker-68vl-4-4-compression-tube-connector-brass-1-4-18","provider":"Voomi Supply","version":"1.0","type":"link"}
