It features a multiple-barb design on both ends, which provides a secure mechanical grip on the tubing without requiring clamps in light-duty applications. The fitting accepts tubing with an inside diameter of 0.17 x 0.17 inches and an outside diameter of 1\/4 inch. Fabricated from brass, it offers good corrosion resistance and compatibility with a wide range of non-aggressive media. HVAC technicians, plumbers, and refrigeration service techs install this type of fitting when making inline tubing connections in tight spaces or low-pressure secondary circuits.\u003c\/p\u003e\u003cp\u003eThis barbed tube union is suited for residential and light commercial applications where flexible tubing — such as polyethylene, vinyl, or similar soft-wall tubing — must be joined in-line. Common install scenarios include condensate drain lines, chemical feed tubing, instrumentation sampling lines, and low-pressure pneumatic control circuits. The compact brass body makes it a practical choice where space is limited and a solderless, tool-free connection is acceptable for the service conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultiple-barb profile on both ends for a secure grip on soft-wall tubing\u003c\/li\u003e\n\u003cli\u003eBrass construction provides corrosion resistance in a broad range of fluid service environments\u003c\/li\u003e\n\u003cli\u003eAccepts 0.17 x 0.17 inch inside diameter tubing with 1\/4 inch outside diameter\u003c\/li\u003e\n\u003cli\u003eSolderless, push-on installation requires no special tooling\u003c\/li\u003e\n\u003cli\u003eCompact union body suitable for tight-space inline connections\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style inline union for flexible soft-wall tubing with a 0.17 inch inside diameter and a 1\/4 inch outside diameter, typical of polyethylene, vinyl, and similar tubing used in low-pressure fluid and pneumatic service lines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis fitting is installed by licensed HVAC technicians, plumbers, or refrigeration mechanics working on low-pressure secondary circuits. Before servicing any connected line, shut off flow and depressurize the system. Push tubing firmly over each barbed end to ensure full seating past all barb ridges. Verify that the tubing wall is free of cuts or deformation before assembly, as a compromised tube wall will not seal reliably on the barbs.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Inside Diameter\u003c\/strong\u003e: 0.17 x 0.17 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePSC Code\u003c\/strong\u003e: 4720\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: 22-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540150518066,"sku":"22-4","price":21.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c90b123f8a1e7ac177018eaec355ed8.jpg?v=1785847197","url":"https:\/\/voomisupply.com\/products\/parker-22-4-barbed-tube-union-0-17-in-id-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
