It mates with compression-style fittings and provides a leak-resistant mechanical connection without the need for flaring the tube end. Manufactured from brass, this nut accepts tubing with a 3\/16-inch outside diameter and uses a 7\/16-24 straight thread. It meets ISO 6149 and SAE J1926 standards, making it suitable for applications where thread-form compliance is required. Plumbers, hydraulic system technicians, and fluid-systems mechanics are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis compression tube nut is used in residential and light commercial fluid-handling systems, hydraulic lines, refrigeration tubing runs, and instrumentation plumbing where NPTF-compatible or straight-thread compression connections are specified. It is well suited to tight-space installations where tube flaring is impractical. The rated temperature range spans -30 degrees F to 135 degrees C, allowing use across a wide range of operating environments from cold ambient conditions to elevated-temperature process lines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction resists corrosion in fluid-handling and refrigeration environments\u003c\/li\u003e\n  \u003cli\u003eAccepts 3\/16-inch outside diameter tubing for precise, secure compression connection\u003c\/li\u003e\n  \u003cli\u003e7\/16-24 straight thread compatible with NPTF port standards\u003c\/li\u003e\n  \u003cli\u003eMeets ISO 6149 and SAE J1926 standards for thread form and sealing performance\u003c\/li\u003e\n  \u003cli\u003eOperating range of -30 degrees F minimum to 135 degrees C maximum\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-piece replacement or repair\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement compression tube nut for fluid system assemblies requiring a 3\/16-inch OD tube connection with a 7\/16-24 straight thread meeting ISO 6149 and SAE J1926 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified hydraulic, plumbing, or refrigeration technician. De-pressurize and isolate the fluid line completely before removing or installing any compression fitting components. Hand-tighten the nut onto the fitting body before applying a wrench to avoid cross-threading the brass threads. Do not overtighten — brass fittings are susceptible to thread damage and ferrule deformation if excess torque is applied beyond snug-plus-standard-turn guidance from the fitting system manufacturer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Compression Tube Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection Type\u003c\/strong\u003e: Compression\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\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStraight Thread Size\u003c\/strong\u003e: 7\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -30 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 135 degrees C\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: 0.01 pounds\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: 61VL-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540275921202,"sku":"61VL-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8e46793b4eba6b7e08c1584a1e8885cd.jpg?v=1785850985","url":"https:\/\/voomisupply.com\/products\/parker-61vl-3-compression-tube-nut-brass-nptf-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
