It uses a 45-degree flare seat and a 1\/2-20 thread to create a leak-tight mechanical closure on refrigerant, fuel, or fluid lines. Rated to 1200 psi maximum working pressure and 250 degrees F maximum working temperature, this cap is built for demanding service environments. The all-brass construction resists corrosion and stands up to the fluids and pressures common in HVAC, refrigeration, and hydraulic applications. HVAC technicians, plumbers, and fluid power mechanics install this fitting as a temporary or permanent line cap during service, repair, or system decommissioning.\u003c\/p\u003e\u003cp\u003eThis cap is suited for use on 5\/16 inch OD flared tube connections in residential and light commercial HVAC systems, refrigeration lines, and hydraulic or fuel circuits wherever a SAE 45-degree flare termination is required. It meets SAE J512 and SAE J513 standards and carries a UL Listing, making it appropriate for code-compliant installations. Typical use cases include capping off unused ports, isolating sections of a refrigerant circuit, or sealing lines during equipment changeout.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-degree flare seat conforms to SAE J512 and SAE J513 flare fitting standards\u003c\/li\u003e\n\u003cli\u003e1200 psi maximum working pressure for reliable performance in high-pressure systems\u003c\/li\u003e\n\u003cli\u003eRated to 250 degrees F, suitable for a wide range of fluid and refrigerant service temperatures\u003c\/li\u003e\n\u003cli\u003eAll-brass construction provides corrosion resistance in refrigerant, fuel, and fluid service\u003c\/li\u003e\n\u003cli\u003eUL Listed for use in code-compliant installations\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 0.62 inches for tight-space applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 5\/16 inch OD tubing terminated with a SAE 45-degree flare, conforming to SAE J512 and SAE J513 standards.

Before installing or removing any flare fitting on a refrigerant or pressurized fluid line, depressurize and recover the system per applicable codes and EPA Section 608 requirements where refrigerants are involved. Hand-tighten the cap onto the flare seat first, then snug with a flare-nut wrench to avoid distorting the brass seat. Do not overtighten, as brass flare fittings are susceptible to deformation under excessive torque.\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: 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: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1200 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: 0.62 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE J512, SAE J513, UL Listing\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-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51543047668018,"sku":"640F-5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cdd0ffbba692a6600f1a245b4d612114.jpg?v=1785914488","url":"https:\/\/voomisupply.com\/products\/parker-640f-5-brass-flared-tube-cap-5-16-in-45-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
