The fitting features a beaded hose barb end for secure hose retention and a threaded male end for connection to hydraulic or fluid system ports. Rated for service from -40 degrees F to 160 degrees F, this fitting suits a wide range of fluid transfer applications in HVAC, plumbing, and light hydraulic systems. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this type of fitting where a reliable hose-to-port transition is required.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and commercial fluid system installations where a 3\/4 inch ID hose must terminate at a straight-thread SAE port. Typical applications include coolant lines, water supply connections, and low-pressure hydraulic circuits. The beaded barb design provides mechanical hose retention, reducing the risk of blowoff under normal working pressures. It is sold individually and is appropriate for use wherever a male SAE straight thread to hose barb transition is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBeaded hose barb end provides positive hose retention and reduces blowoff risk\u003c\/li\u003e\n  \u003cli\u003e3\/4-16 SAE straight thread male end for compatibility with standard port fittings\u003c\/li\u003e\n  \u003cli\u003eAccepts 3\/4 inch inside diameter hose\u003c\/li\u003e\n  \u003cli\u003eBrass construction resists corrosion in water and fluid service\u003c\/li\u003e\n  \u003cli\u003eRated from -40 degrees F to 160 degrees F for a broad service temperature range\u003c\/li\u003e\n  \u003cli\u003eHex head size of 0.875 inches allows use with standard open-end or box wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install male connector fitting for systems using 3\/4 inch ID hose with a 3\/4-16 SAE straight thread port connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or qualified mechanical technicians. Shut off and depressurize the fluid system completely before removing or installing any hose fitting. Use the 0.875 inch hex head with an appropriately sized wrench and apply thread sealant or an SAE-approved O-ring if required by the port design. Do not overtighten; follow the system manufacturer or applicable code guidelines for straight-thread port connections.\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: 3\/4-16\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\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarb Size\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Head Size\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecial Feature\u003c\/strong\u003e: Beaded Hose Barb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 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\u003eWeight\u003c\/strong\u003e: 0.13 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-12-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540546584882,"sku":"685HB-12-8","price":39.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d5da51af90981bb17f58d7ef3e8fcee_031b9e2d-f259-4d4c-ad17-b3515f453abd.jpg?v=1785858138","url":"https:\/\/voomisupply.com\/products\/parker-685hb-12-8-barbed-hose-fitting-male-connector","provider":"Voomi Supply","version":"1.0","type":"link"}
