Molded from white nylon, this straight union accepts 3\/8-inch inside diameter tubing on both ends with a 0.43-inch outside diameter profile. It carries FDA compliance and NSF\/ANSI 51 certification, making it appropriate for food equipment and potable water applications. The connector handles working pressures up to 125 psi and operates across a temperature range of -40 degrees F to 200 degrees F. Plumbers, HVAC technicians, and food-service equipment installers commonly use this fitting during new installations and service calls.\u003c\/p\u003e\u003cp\u003eThe PARKER 322HB-6N suits residential and light commercial applications where flexible tubing must be spliced or connected within tight spaces. Typical installations include ice makers, water filtration systems, beverage dispensing equipment, and HVAC condensate drain lines where NSF or FDA compliance is required. Its nylon construction resists corrosion and keeps weight minimal in low-pressure fluid circuits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle-barb design on both ends secures 3\/8-inch ID flexible tubing without additional fittings\u003c\/li\u003e\n\u003cli\u003eNylon construction provides corrosion resistance across a wide temperature range\u003c\/li\u003e\n\u003cli\u003eRated to 125 psi working pressure for reliable performance in low-to-medium pressure circuits\u003c\/li\u003e\n\u003cli\u003eFDA compliant and NSF\/ANSI 51 certified for food equipment and potable water contact applications\u003c\/li\u003e\n\u003cli\u003eOperating range of -40 degrees F to 200 degrees F suits both cold and hot fluid service\u003c\/li\u003e\n\u003cli\u003eOverall length of 1.61 inches allows installation in confined plumbing and equipment spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with flexible tubing having a 3\/8-inch inside diameter and a 0.43-inch outside diameter in low-pressure fluid handling systems requiring FDA or NSF\/ANSI 51 compliance.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed plumbers or qualified HVAC or equipment service technicians. Shut off the water supply and relieve system pressure before disconnecting or installing any tubing fitting. Ensure tubing is cut cleanly and squarely, and push tubing fully onto each barb until it seats against the fitting body for a secure, leak-free connection. Verify that all materials and system pressures remain within the rated specifications for this fitting before returning the system to service.\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\u003eMaterial\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Barbs\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarb Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Inside Diameter\u003c\/strong\u003e: 3\/8 x 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 0.43 x 0.43 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\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-6N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540802863410,"sku":"322HB-6N","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f0a4196c2acfcafc3132b9ce35cfec8_153762bd-9011-4b3c-9bbd-79d8cf649a90.jpg?v=1785864164","url":"https:\/\/voomisupply.com\/products\/parker-322hb-6n-barbed-tube-union-connector-3-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
