Constructed from nylon, this fitting offers lightweight corrosion resistance suitable for low-pressure plumbing, irrigation, and general fluid-handling systems. The stepped barb configuration accepts a 1\/2-inch barb on one end and a 3\/8-inch barb on the other, allowing technicians to transition between two different tubing inside diameters within a single inline connection. The white nylon body makes it easy to visually identify in bundled line assemblies. Licensed plumbers, HVAC technicians, and irrigation specialists are the typical installers for this type of fitting.\u003c\/p\u003e\u003cp\u003eThis union connector is suited for residential and light commercial applications where flexible tubing runs require an inline splice or a barb-size transition. Common installation scenarios include potable water dispensing lines, condensate drain connections, irrigation distribution tubing, and low-pressure pneumatic circuits. The 1\/2 x 3\/8-inch barb sizing makes it a practical solution wherever a line reduces or steps down between two common small-diameter tubing sizes within the same run.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStepped barb design transitions between 1\/2-inch and 3\/8-inch tubing inside diameters in a single fitting\u003c\/li\u003e\n\u003cli\u003eNylon construction provides corrosion resistance and chemical compatibility with common water-based and low-pressure fluid media\u003c\/li\u003e\n\u003cli\u003eUnion connector style enables inline joining of two tubing sections without tools or clamps on the barb itself\u003c\/li\u003e\n\u003cli\u003eWhite color aids visual identification in multi-line installations\u003c\/li\u003e\n\u003cli\u003eCompact, lightweight form at 0.01 pounds adds negligible weight to any assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for flexible tubing systems requiring a barbed union connection between 1\/2-inch and 3\/8-inch inside-diameter tubing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis fitting is typically installed by licensed plumbers or qualified HVAC and irrigation technicians. Shut off the fluid supply and relieve any line pressure before removing existing fittings or cutting into a tubing run. Push tubing firmly over each barb to the full depth of the barb retention ribs; hose clamps or crimp rings are recommended for pressurized applications to prevent pull-off. Follow all applicable IPC or local plumbing code requirements for the specific fluid media and pressure rating of the system.\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 Size\u003c\/strong\u003e: 1\/2 x 3\/8 inches\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\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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-8-6N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542233514290,"sku":"322HB-8-6N","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f0a4196c2acfcafc3132b9ce35cfec8_de8907c0-a7df-4da9-97df-2de3937b2611.jpg?v=1785895866","url":"https:\/\/voomisupply.com\/products\/parker-322hb-8-6n-barbed-tube-union-connector","provider":"Voomi Supply","version":"1.0","type":"link"}
