It features a 7\/16-20 SAE straight thread on one end and a beaded hose barb sized for 1\/4 inch inside diameter hose on the other. The beaded barb profile grips the hose wall to resist pull-off under pressure and vibration. Rated for a working temperature range of -40 degrees F to 160 degrees F, this fitting is suited for hydraulic, pneumatic, and fluid transfer lines found in HVAC, refrigeration, and light industrial plumbing applications. Plumbers, HVAC technicians, and fluid system assemblers install this type of fitting as a standard service or OEM replacement component.\u003c\/p\u003e\n\u003cp\u003eThis fitting is appropriate for low-pressure fluid or gas lines where a flexible hose must terminate at a straight-threaded port. Typical applications include refrigerant oil lines, condensate and coolant hoses, and hydraulic control circuits in both residential and light commercial equipment. The straight thread engagement requires a sealing method at the port face, such as an O-ring boss seat, rather than relying on thread taper for the seal. The compact overall length of 1.4 inches makes it practical in confined equipment cabinets and control compartments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBeaded hose barb for 1\/4 inch ID hose provides enhanced grip and pull-off resistance\u003c\/li\u003e\n  \u003cli\u003e7\/16-20 SAE straight thread for use with O-ring boss or similar straight-thread ports\u003c\/li\u003e\n  \u003cli\u003eBrass construction resists corrosion in water, oil, and refrigerant-adjacent service\u003c\/li\u003e\n  \u003cli\u003eWorking temperature range: -40 degrees F to 160 degrees F (-40 degrees C to 71.1 degrees C)\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1.4 inches suits tight installation spaces\u003c\/li\u003e\n  \u003cli\u003e0.5625 inch hex head allows standard wrench engagement for controlled installation torque\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/4 inch inside diameter flexible hose and SAE 7\/16-20 straight-thread ports in fluid transfer, hydraulic, and HVAC control line applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or hydraulic system technicians. De-pressurize and drain the line completely before removing or installing any hose fitting. SAE straight threads do not self-seal on the thread form — confirm the mating port has a functional O-ring boss or face seal arrangement before assembly. Use a wrench on the hex head only; do not grip the barb shank to avoid distorting the sealing geometry.\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 Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: SAE Straight Thread\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: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarb Size\u003c\/strong\u003e: 0.2500 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: 1.4 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\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: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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-4-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541449474354,"sku":"685HB-4-4","price":17.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d5da51af90981bb17f58d7ef3e8fcee_9d27a219-b154-4704-92e2-8729b6c6aa0a.jpg?v=1785876509","url":"https:\/\/voomisupply.com\/products\/parker-685hb-4-4-brass-male-hose-barb-fitting-7-16-20","provider":"Voomi Supply","version":"1.0","type":"link"}
