Molded from white nylon, this straight union fits tubing with a 3\/16 inch inside diameter and a 0.25 inch outside diameter on each end. It carries an overall length of 1.61 inches and is rated for working pressures up to 125 psi. The fitting meets FDA compliance and NSF\/ANSI 51 certification, making it suitable for applications involving food-zone or potable-water-adjacent fluid handling. Licensed plumbers, HVAC technicians, and equipment service techs are the typical installers.\u003c\/p\u003e\u003cp\u003eThis union connector is used in residential and light commercial installations where two sections of small-bore flexible tubing must be joined inline. Common applications include condensate drain lines, refrigeration equipment, beverage dispensing equipment, ice machines, and other food-service or fluid-handling assemblies that require NSF\/ANSI 51 compliant components. The nylon construction handles a temperature range of -40 degrees F to 200 degrees F, covering most standard indoor service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle-barb design on each end locks tubing in place without clamps in low-pressure service\u003c\/li\u003e\n\u003cli\u003eNylon construction resists corrosion and is compatible with a broad range of non-aggressive fluids\u003c\/li\u003e\n\u003cli\u003eRated to 125 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eOperating temperature range from -40 degrees F to 200 degrees F (-40 degrees C to 93.3 degrees C)\u003c\/li\u003e\n\u003cli\u003eFDA compliant and NSF\/ANSI 51 certified for food-equipment fluid contact\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 1.61 inches for tight-space installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with flexible tubing having a 3\/16 inch inside diameter and a 0.25 inch outside diameter.

Push tubing fully onto each barb until it seats against the fitting body; hose clamps may be added where pressure cycling or vibration is present. This fitting is intended for use within its rated pressure and temperature limits — do not use in systems exceeding 125 psi or 200 degrees F. Installation in potable water or food-contact equipment should comply with applicable local plumbing codes and NSF\/ANSI 51 requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Union Connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarb Configuration\u003c\/strong\u003e: Single Barb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarb Size\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Inside Diameter\u003c\/strong\u003e: 3\/16 x 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 0.25 x 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.61 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 125 psi\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\u003eMaximum Working Temperature\u003c\/strong\u003e: 200 degrees F (93.3 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: FDA Compliant, NSF\/ANSI 51\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 322HB-3N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538952552754,"sku":"322HB-3N","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f0a4196c2acfcafc3132b9ce35cfec8.jpg?v=1785830712","url":"https:\/\/voomisupply.com\/products\/parker-322hb-3n-barbed-tube-union-connector-3-16-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
