It features a 7\/16-20 SAE straight thread on one end and a beaded hose barb on the other, accepting 3\/8 inch inside diameter hose. The beaded barb profile improves hose retention under pressure and vibration. Rated for service from -40 degrees F to 160 degrees F, this fitting suits a wide range of industrial and mobile equipment fluid transfer applications. Licensed plumbers, HVAC technicians, and equipment mechanics routinely specify this type of fitting for low-pressure fluid and refrigerant-compatible line connections.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial applications where a threaded port must transition to a flexible hose run. It is commonly installed in HVAC equipment condensate and refrigerant line assemblies, hydraulic power units, and general-purpose fluid transfer systems that use 3\/8 inch ID hose terminated at an SAE straight-thread port. The 7\/16-20 thread size is a standard SAE designation found on OEM equipment ports across multiple industries.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBeaded hose barb profile improves grip and reduces hose blowoff risk\u003c\/li\u003e\n  \u003cli\u003e7\/16-20 SAE straight thread for positive, non-tapered port engagement\u003c\/li\u003e\n  \u003cli\u003eAccepts 3\/8 inch inside diameter hose\u003c\/li\u003e\n  \u003cli\u003eBrass construction resists corrosion in fluid transfer service\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -40 degrees F to 160 degrees F\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 1.39 inches fits tight installation spaces\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 equipped with 7\/16-20 SAE straight-thread ports and 3\/8 inch ID flexible hose connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or qualified mechanics. Depressurize and drain the system fully before removing or installing any hose fitting. Apply a suitable thread sealant or O-ring to the SAE straight thread port as required by the equipment manufacturer; SAE straight threads are not self-sealing by thread form alone. Ensure the hose is fully seated past the bead before applying a clamp to maintain a secure, leak-free connection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Male Connector\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: SAE Straight Thread\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Hose Barb x SAE Straight Thread\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHose Inside Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarb Size\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Head Size\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 160 degrees F (71.1 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F (-40 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecial Feature\u003c\/strong\u003e: Beaded Hose Barb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: 685HB-6-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539179602226,"sku":"685HB-6-4","price":18.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d5da51af90981bb17f58d7ef3e8fcee.jpg?v=1785836062","url":"https:\/\/voomisupply.com\/products\/parker-685hb-6-4-barbed-hose-fitting-3-8-id-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
