The tee configuration features two 3\/8-inch OD connections and one 1\/4-inch OD connection, all with male flare ends. Flare fittings create a leak-resistant mechanical seal without solder, making them a common choice in systems where field serviceability and reusability matter. Licensed HVAC technicians and plumbers install this type of fitting when branching a line set or routing flow to multiple components in a system.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for residential and light commercial refrigerant line applications, as well as gas and fuel line assemblies where flare connections are specified. The tee configuration allows a single supply line to feed two branch lines, or two lines to merge into one, depending on system layout. It is appropriate for use in new installations and service replacements where existing flare connections are present.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMale flare ends on all three ports for secure mechanical seals without solder\u003c\/li\u003e\n\u003cli\u003eTee configuration supports line branching or combining in refrigerant and gas systems\u003c\/li\u003e\n\u003cli\u003eTwo 3\/8-inch OD ports and one 1\/4-inch OD port for multi-size line connections\u003c\/li\u003e\n\u003cli\u003eReusable connection type suited for field service and system modifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation flare tee for HVAC, refrigeration, and gas line systems using standard male flare connections at 3\/8-inch and 1\/4-inch OD tubing sizes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber in accordance with applicable local codes and ASHRAE or IFGC guidelines. Recover and isolate refrigerant or shut off gas supply before disconnecting or installing any fitting. Use a calibrated flaring tool to ensure proper flare geometry on field-cut tubing, and inspect all flare seats for burrs or damage before assembly. Do not overtighten flare nuts, as this can crack the flare seat and cause leaks.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Tee\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Male Flare\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort 1 OD Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort 2 OD Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort 3 OD Size\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HOLYOKE FITTINGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 44R-664\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLYOKE FITTINGS","offers":[{"title":"Default Title","offer_id":51383689412914,"sku":"44R-664","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670778.png?v=1782604475","url":"https:\/\/voomisupply.com\/products\/holyoke-fittings-44r-664-male-flare-tee-3-8x3-8x1-4-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
