Molded from polypropylene, this fitting accepts 3\/16-inch barb connections on both ends and accommodates tubing with a 3\/16-inch inside diameter and a 0.25-inch outside diameter. It is rated for working pressures up to 125 psi and a maximum working temperature of 212 degrees F, making it suitable for a range of fluid-transfer and low-pressure line applications. The connector meets FDA compliance and NSF\/ANSI 51 certification requirements, qualifying it for food-equipment and potable-water-contact environments. Licensed plumbers, HVAC technicians, and fluid-systems installers are the typical end users for this fitting type.\u003c\/p\u003e\n\u003cp\u003eThis union connector is commonly used in low-pressure fluid-handling systems including food-service equipment, water-purification assemblies, beverage dispensing lines, and HVAC condensate or drain tubing. Its barbed design provides a friction-retention fit on compatible flexible tubing, and the straight union configuration allows inline splicing or repair of existing tubing runs. The compact overall length of 1.61 inches makes it practical in tight equipment enclosures or panel-mounted assemblies. It is suited for both residential and light commercial applications where a clean, chemical-resistant polypropylene fitting is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-barb union connector joins two 3\/16-inch ID flexible tube segments inline\u003c\/li\u003e\n  \u003cli\u003ePolypropylene construction provides chemical resistance and lightweight durability\u003c\/li\u003e\n  \u003cli\u003eRated to 125 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range from 0 degrees F to 212 degrees F\u003c\/li\u003e\n  \u003cli\u003eFDA compliant and NSF\/ANSI 51 certified for food-equipment and potable-water contact\u003c\/li\u003e\n  \u003cli\u003eCompact 1.61-inch overall length suits restricted installation spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit barbed union connector for flexible tubing with a 3\/16-inch inside diameter and 0.25-inch outside diameter.

Shut off and depressurize the fluid line before removing or replacing any fitting in the assembly. Ensure tubing is cut cleanly and squarely to achieve a full barb engagement and minimize leak risk. This fitting is not intended for high-pressure, steam, or gas service outside its rated working conditions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 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\u003eNumber of Barbs\u003c\/strong\u003e: Single\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\u003eMaximum Working Temperature\u003c\/strong\u003e: 212 degrees F (100 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: 0 degrees F (-12.2 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\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  \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\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: 322HB-3PP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542310060338,"sku":"322HB-3PP","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1930513671440f085ac0a258d84867e_f32cf08d-fe78-4a83-ae41-b547fafdb6a3.jpg?v=1785897703","url":"https:\/\/voomisupply.com\/products\/parker-322hb-3pp-barbed-tube-union-connector-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
