It uses a 45-degree SAE flare end connection and a 3\/4-16 thread to create a pressure-tight closure on open tube ends. Rated to 750 psi maximum working pressure and a maximum working temperature of 250 degrees F, this cap is built for demanding service in refrigeration, HVAC, and hydraulic tubing systems. The all-brass construction resists corrosion and withstands the mechanical stress of repeated service work. Licensed HVAC technicians and plumbers use this fitting to cap off unused ports, isolate sections of a system during service, or permanently close decommissioned lines.\u003c\/p\u003e\u003cp\u003eThis cap is suited for residential and light commercial applications where SAE 45-degree flare fittings are standard. Typical installation scenarios include capping refrigerant line sets, hydraulic tubing, or fuel and oil lines during system maintenance or when a port is taken out of service. The fitting meets SAE J512 and SAE J513 standards and carries a UL Listing, making it appropriate for systems that require documented compliance. With an overall length of 0.84 inches and a weight of 0.06 pounds, it is a compact, lightweight cap that fits easily into a technician's fitting kit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-degree SAE flare end connection for a leak-free pressure seal\u003c\/li\u003e\n\u003cli\u003e3\/4-16 thread size compatible with standard SAE flare tube fittings\u003c\/li\u003e\n\u003cli\u003eRated to 750 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eMaximum working temperature of 250 degrees F (121 degrees C)\u003c\/li\u003e\n\u003cli\u003eMeets SAE J512, SAE J513, and carries UL Listing\u003c\/li\u003e\n\u003cli\u003eAll-brass construction for corrosion resistance and durability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1\/2-inch OD tubing using 45-degree SAE flare end connections per SAE J512 and SAE J513 standards.

Depressurize and isolate the line completely before removing any existing fitting or installing this cap. Hand-tighten the cap onto the flared tube end first to ensure proper thread engagement, then tighten with an appropriately sized open-end wrench — do not overtighten, as brass threads can be damaged. Verify the flare seat is clean and undamaged before assembly to ensure a leak-free seal.\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: Cap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: 45-Degree Flare\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 750 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: 0.84 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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\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: 640F-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542215688498,"sku":"640F-8","price":34.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2dc790f18855a8cd208cac08b1626622.jpg?v=1785895372","url":"https:\/\/voomisupply.com\/products\/parker-640f-8-brass-flared-tube-cap-1-2-in-45-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
