With a 37-degree flare angle and flare-by-flare end connections, this union provides a leak-resistant metal-to-metal seal rated for working pressures up to 4500 psi. It accepts 3\/4 inch tube OD and is built from steel for durability in demanding service conditions. Licensed HVAC technicians, plumbers, and hydraulic system installers use this type of fitting when connecting or repairing tube runs that require a reliable, removable union joint in tight spaces or service points.\u003c\/p\u003e\n\u003cp\u003eThis flared tube union suits residential and commercial applications where tube lines must be joined or disconnected for service. Common installations include refrigerant line sets, hydraulic circuits, and high-pressure pneumatic plumbing. The 37-degree flare angle conforms to SAE J514 and SAE J1453 standards, making it compatible with standard SAE 37-degree flared fittings used throughout HVAC, fluid power, and industrial plumbing trades. The fitting tolerates operating temperatures up to 500 degrees F, extending its usefulness across a wide range of system environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e37-degree flare angle meets SAE J514, SAE J1453, and ISO 8434-1 standards\u003c\/li\u003e\n  \u003cli\u003eMaximum working pressure of 4500 psi for high-pressure service\u003c\/li\u003e\n  \u003cli\u003eMaximum working temperature of 500 degrees F (260 degrees C)\u003c\/li\u003e\n  \u003cli\u003eFlare x Flare end connections for a secure metal-to-metal seal\u003c\/li\u003e\n  \u003cli\u003eSteel construction for strength and resistance in hydraulic and pneumatic service\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 2\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 37-degree flared tube connections with 3\/4 inch tube OD.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber, HVAC technician, or hydraulic systems mechanic. Always depressurize and isolate the line before disassembling or installing flared tube fittings. Ensure mating flare seats are clean and free of burrs or debris before assembly to achieve a proper metal-to-metal seal. Follow applicable system codes and the fitting manufacturer torque guidelines for the specific tube material and wall thickness in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare x Flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 4500 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 500 degrees F (260 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 8434-1, SAE J1453, SAE J514\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2\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: PT-00137\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539472023858,"sku":"PT-00137","price":198.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2df85a2b7ac8f36783860e1fbfae6f81.jpg?v=1785840932","url":"https:\/\/voomisupply.com\/products\/parker-pt-00137-steel-flared-tube-union-3-4-in-37-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
