It threads onto a standard 45-degree SAE flare fitting, providing a leak-tight closure rated to 1400 psi maximum working pressure and 250 degrees F maximum working temperature. The all-brass construction resists corrosion and holds up in both liquid and gas service. HVAC technicians, refrigeration mechanics, and plumbers install this bonnet when a flare port needs to be temporarily or permanently sealed during system maintenance, pressure testing, or equipment changeover.\u003c\/p\u003e\u003cp\u003eThis seal bonnet is suited for residential and light commercial HVAC systems, refrigeration lines, hydraulic circuits, and pneumatic plumbing where a 45-degree SAE flare connection is present. It is commonly used on service valves, manifold ports, and branch-line terminations. The 1\/4-inch tube OD sizing covers the flare end directly, making it straightforward to apply on standard refrigerant or compressed-air lines without additional adapters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-inch tube OD with 45-degree flare end connection\u003c\/li\u003e\n\u003cli\u003eRated to 1400 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eRated to 250 degrees F maximum working temperature\u003c\/li\u003e\n\u003cli\u003eBrass construction for corrosion resistance in gas and liquid service\u003c\/li\u003e\n\u003cli\u003eMeets SAE J512, SAE J513, and UL Listing standards\u003c\/li\u003e\n\u003cli\u003eCompact seal bonnet design for capping unused or inactive flare ports\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement seal bonnet for any system using standard 45-degree SAE flare fittings with 1\/4-inch tube OD connections, per SAE J512 and SAE J513 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed HVAC technicians, refrigeration mechanics, or plumbers. Before installing or removing a seal bonnet on a live system, relieve system pressure and follow all applicable safety procedures. Use an appropriately sized flare wrench to avoid rounding the bonnet hex; do not overtighten. Verify the mating flare surface is clean and free of damage before seating the bonnet.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: Seal Bonnet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1400 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F (121 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE J512, SAE J513, UL Listing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\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: 3GF-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542128296242,"sku":"3GF-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2dd9b00e3e92c47ee97266ca25477ec.jpg?v=1785892940","url":"https:\/\/voomisupply.com\/products\/parker-3gf-4-brass-flared-tube-seal-bonnet-1-4-in-45-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
