The multiple-barb design grips the inner wall of the tubing to create a secure, pull-resistant seal without the need for clamps or adhesives. With a tube inside diameter of 0.17 inches and a tube outside diameter of 0.25 inches, this plug is sized for small-bore tubing commonly found in HVAC, refrigeration, plumbing, and light industrial applications. Licensed tradespeople and technicians install these plugs when capping unused tubing ports or isolating a section of a fluid circuit during service.\u003c\/p\u003e\n\u003cp\u003eThis plug is suited for low-pressure fluid or air line applications where a compact, reusable end-seal is needed. It is commonly used in residential and light commercial HVAC equipment, condensate drain lines, and pneumatic control tubing. The brass construction makes it appropriate for applications where corrosion resistance and moderate pressure handling are required. Installers typically use this type of plug when decommissioning a branch line or capping a tubing run during system modifications or repairs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultiple-barb profile locks into tubing inner wall for a secure, clamp-free seal\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance in fluid and air service\u003c\/li\u003e\n  \u003cli\u003eFits tubing with 0.17 inch inside diameter and 0.25 inch outside diameter\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suits tight spaces inside equipment cabinets and panels\u003c\/li\u003e\n  \u003cli\u003eNo tools required for installation into flexible tubing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for flexible tubing with a 0.17 inch inside diameter and 0.25 inch outside diameter in fluid handling or pneumatic systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by plumbers, HVAC technicians, or pipefitters working on low-pressure tubing systems. Before installing, shut off fluid supply or depressurize the pneumatic circuit completely. Push the barbed plug firmly into the tubing end until the barbs seat fully against the inner wall. Verify the tubing is free of cuts or splits at the end before plugging, as damaged tubing will not hold the barb securely.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Inside Diameter\u003c\/strong\u003e: 0.17 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarb Style\u003c\/strong\u003e: Multiple Barbs\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: 20-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542253109554,"sku":"20-4","price":20.01,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7b4a12fc3851b7b11ffe5078d0fa44c.jpg?v=1785896454","url":"https:\/\/voomisupply.com\/products\/parker-20-4-barbed-tube-plug-brass-0-17-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
