Machined from solid brass, this fitting accepts a 3\/8 inch barb on one end and threads onto a 5\/8 inch UNF female thread on the other, creating a reliable transition between a threaded port and a flexible hose line. With a maximum working pressure of 300 psi and a temperature range of -40 degrees F to 212 degrees F, it handles demanding service conditions in both liquid and low-pressure pneumatic systems. Plumbers, HVAC technicians, and mechanical contractors install this fitting during equipment hookups and system assemblies.\u003c\/p\u003e\n\u003cp\u003eThis connector is suited for residential and light commercial plumbing, HVAC, and industrial fluid-handling systems where a threaded port must be joined to a flexible hose. The 3\/8 inch barb accommodates standard 3\/8 inch inside diameter hose, and the 5\/8 inch UNF thread provides a positive mechanical connection to compatible ported components. Its all-brass construction resists corrosion in water, oil, and many mild chemical service environments, making it a practical choice for equipment manifolds, service valves, and fluid lines that see regular pressure cycling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch barb accepts standard 3\/8 inch ID push-on or clamp hose\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch UNF female thread for positive port engagement\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance in water and oil service\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to 212 degrees F\u003c\/li\u003e\n  \u003cli\u003eCompact, single-piece design with no secondary sealing components required on the barb side\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for systems using 5\/8 inch UNF threaded ports paired with 3\/8 inch inside diameter flexible hose lines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or qualified mechanical technicians. Depressurize and drain the system fully before removing or installing any fittings. Apply thread sealant or PTFE tape to the UNF male threads of the mating port per local plumbing code requirements, and secure the hose to the barb with an appropriate clamp rated for the working pressure. Do not exceed the 300 psi maximum working pressure rating of this fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Female\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarb Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 212 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141734\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: CERROBRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 307-66\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CERROBRASS","offers":[{"title":"Default Title","offer_id":67912719761714,"sku":"307-66","price":19.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69a71fd28256f3f86db1efdfdd77cf05.jpg?v=1791238561","url":"https:\/\/voomisupply.com\/products\/cerrobrass-307-66-barbed-hose-female-connector-3-8-barb","provider":"Voomi Supply","version":"1.0","type":"link"}
