Molded from polypropylene, this fitting resists common chemicals and moisture, making it well-suited for low-pressure fluid transfer lines in HVAC condensate, plumbing, pool, and general pneumatic or liquid-handling applications. The 5\/16 inch barb size secures standard flexible tubing with a push-on fit, and the black color aids quick visual identification in mixed-line installations. Licensed plumbers, HVAC technicians, and pool service professionals install this type of fitting where a leak-resistant, tool-free tube connection is needed in tight or remote service locations.\u003c\/p\u003e\n\u003cp\u003eThis union connector is used in residential and light commercial systems where flexible tubing runs require a mid-line splice or a field connection between two tube ends. Typical install scenarios include condensate drain lines, chemical feed lines, irrigation sub-lines, and pool or spa equipment plumbing where polypropylene chemical compatibility is an advantage over metal fittings. The 5\/16 inch barb size matches common small-bore flexible tubing used throughout these trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUnion connector design joins two flexible tube ends in a straight-line configuration\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch barbs provide a secure push-on grip without clamps or tools in low-pressure service\u003c\/li\u003e\n  \u003cli\u003ePolypropylene construction offers chemical and moisture resistance\u003c\/li\u003e\n  \u003cli\u003eBlack color aids visual identification in multi-line installations\u003c\/li\u003e\n  \u003cli\u003eCompact form factor fits in confined equipment bays and tight plumbing chases\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or field-install fitting for 5\/16 inch inside diameter flexible tubing used in low-pressure HVAC, plumbing, pool, and fluid transfer applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is installed by HVAC technicians, plumbers, and pool service professionals working on low-pressure fluid lines. Before servicing any connected system, shut off the fluid supply and relieve line pressure. Ensure the tubing inner diameter matches the 5\/16 inch barb size for a secure, leak-free connection. For pressurized lines, verify the operating pressure does not exceed the rating of both the fitting and the tubing being used.\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: 5\/16 inches\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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-5PP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539062751538,"sku":"322HB-5PP","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bdf69b9b11ecaf61256bfab200bb9c2_c338e155-69f9-4576-b3a1-0256b0a1b959.jpg?v=1785834051","url":"https:\/\/voomisupply.com\/products\/parker-322hb-5pp-barbed-tube-union-5-16-in-polypropylene","provider":"Voomi Supply","version":"1.0","type":"link"}
