It uses a 45-degree flare seat and a 7\/16-20 thread to create a leak-resistant termination point on refrigerant, hydraulic, or fluid lines. Rated to 1,400 psi maximum working pressure and 250 degrees F, this cap handles the demands of refrigeration and HVAC service work. At 0.53 inches overall length and 0.02 pounds, it installs quickly and fits flush in tight spaces. HVAC technicians and plumbers use it to cap unused ports, isolate line sections during service, or terminate dead-end runs permanently.\u003c\/p\u003e\n\u003cp\u003eThis flare cap is suited for residential and light commercial HVAC systems, refrigeration equipment, and fluid-handling assemblies where SAE 45-degree flare fittings are standard. It is commonly installed on suction or liquid line ports, service valve outlets, and manifold tee branches that require sealing. Applications span air conditioning systems, refrigerant piping, and hydraulic lines requiring a secure, pressure-rated termination. It meets SAE J512, SAE J513, and UL Listing standards, making it appropriate for code-compliant installations across a range of trade work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree flare seat conforms to SAE J512 and SAE J513 standards\u003c\/li\u003e\n  \u003cli\u003eBrass construction resists corrosion in refrigerant and fluid service\u003c\/li\u003e\n  \u003cli\u003eRated to 1,400 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eRated to 250 degrees F maximum working temperature\u003c\/li\u003e\n  \u003cli\u003eCompact 0.53-inch overall length for use in confined spaces\u003c\/li\u003e\n  \u003cli\u003eUL Listed for compliant installations\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 SAE 45-degree flare tube connections with 1\/4-inch OD tubing and 7\/16-20 thread size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or plumbers. Isolate and recover any refrigerant or depressurize the fluid system before removing or capping any line connection. Hand-tighten the cap onto the flare seat before applying a wrench to avoid cross-threading the soft brass threads. Do not overtighten, as brass flare fittings can deform the seat and cause leaks.\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: Cap\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\u003eTube OD\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1,400 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\u003eOverall Length\u003c\/strong\u003e: 0.53 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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\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: 640F-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51543378166066,"sku":"640F-4","price":16.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/facd2bc1f00fb08dd49deee4a4a4a56e.jpg?v=1785917465","url":"https:\/\/voomisupply.com\/products\/parker-640f-4-brass-flared-tube-cap-1-4-in-45-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
